F1 — IP Interfaces
Goals
Build a lab network to learn the commands needed to add IP interfaces to SAOS 10x nodes. By the end of this lab you will be able to:
- Create loopback and IP interfaces using the SAOS 10x CLI
- Configure classifiers, forwarding domains, and flow points to support IP services
- Assign IPv4 and IPv6 addresses to interfaces
- Verify connectivity between directly-connected nodes
Prerequisites
- Complete F0 — SAOS Fundamentals
- ContainerLab installed and accessible
- SAOS 10x image
vrnetlab/ciena_saos:10-12-00-0228(release 10.12.00.0228) available in the container registry - Activate the built-in trial license after deployment
Topology
The physical topology already matches S2. PE_1 and PE_2 use the active foundation link; CE_1, CE_2, PE_3, and the future service/underlay links are shown in gray because F1 does not configure or test them.
Resource note: If you do not plan to continue into the Services track and your host is resource constrained, you may comment out CE_1, CE_2, PE_3, and every link except
[ "PE_1:1", "PE_2:1" ]in your localtopo.clab.yml.
The topology diagrams are topo.clab.svg (physical connectivity) and
topo.detail.svg (annotated view with addressing).
IP Address Table
| Node | Interface | IPv4 Address | IPv6 Address |
|---|---|---|---|
| PE_1 | lb1 | 172.16.0.1/32 | FC00::1/128 |
| PE_1 | PE_1-PE_2-if | 172.16.1.1/30 | FC00::600/127 |
| PE_2 | lb1 | 172.16.0.2/32 | FC00::2/128 |
| PE_2 | PE_1-PE_2-if | 172.16.1.2/30 | FC00::601/127 |
SAOS display note:
show ip interfacesreports IPv4 address and prefix-length as separate fields — not CIDR notation (you will see172.16.1.1and30on separate columns, not172.16.1.1/30). IPv6 addresses are shown fully expanded. Keep this in mind when reading verification output.

Instructions
- Task 1: Verify the deployed topology
- Task 2: Configure IP address on port 1 of PE_1
- Task 3: Configure IP address on port 1 of PE_2
- Task 4: Confirm the IP configuration
- Task 5: Apply IPv6 addresses
- Task 6: Confirm the IPv6 configuration
Task 1: Verify the deployed topology
Summary — Every lab in this series deploys the same six-node
topology — three PEs, each with its own customer edge — but only PE_1
and PE_2 are in play here — they connect
back-to-back on port 1. Before configuring anything, confirm the wiring
matches the diagram: verifying physical adjacency first means any later
reachability problem is a configuration problem, not a cabling one.
Implementation — Nothing to configure yet. SAOS 10x runs LLDP out of the box, so a fresh router already advertises its hostname to its neighbors — inspect each PE's neighbor table for its peer.
Each PE's neighbor table should show its peer on interface 1, keyed by
system-name. Note what LLDP hands you for free — the far-end chassis
MAC, port id, even max-frame-size — worth a glance now, since MTU
becomes a theme in the next task.

Task 2: Configure IP address on port 1 of PE_1
Summary — This task builds PE_1's entire L3 identity from
scratch, and in doing so introduces the SAOS 10x layering model: a
loopback for the router's stable identity and a routed interface for
the point-to-point link, plus the L2 plumbing underneath them.
Background — Unlike platforms where you type an address directly
onto a port, SAOS 10x separates frame selection from forwarding
from routing: a classifier describes which frames to match (here,
untagged ones), a flow-point binds a logical port plus that
classifier into a forwarding-domain (an L2 switching context,
vpls mode), and the IP interface — an oc-if:interfaces object
in the openconfig style — attaches to that FD via an
underlay-binding. The names encode the relationships: everything
scoped to this link shares the PE_1-PE_2 prefix (-FD, -FP,
-if), so cross-references are readable at a glance.
Implementation — In plain steps:
- Create the forwarding-domain
PE_1-PE_2-FDin vpls mode — the L2 context the routed interface will ride on. - Create loopback
lb1and give it172.16.0.1/32— the router's stable identity, independent of any physical port. - Create IP interface
PE_1-PE_2-ifwith MTU 1500, bind it to the FD, and address it172.16.1.1/30for the point-to-point link. - Create
CLASSIFIER-UNTAGGEDto match untagged frames, then flow-pointPE_1-PE_2-FPtying port 1 plus that classifier into the FD.
Note the two MTUs: the flow-point's frame-level ceiling of 2000 must
leave headroom above the IP interface's mtu of 1500 — the flow-point
carries the whole Ethernet frame, the IP interface only the packet.
Configure (config mode) on PE_1:
fds fd PE_1-PE_2-FD mode vpls
oc-if:interfaces interface lb1 config name lb1 type loopback
oc-if:interfaces interface lb1 ipv4 addresses address 172.16.0.1 config ip 172.16.0.1 prefix-length 32
oc-if:interfaces interface PE_1-PE_2-if config mtu 1500 name PE_1-PE_2-if type ip
oc-if:interfaces interface PE_1-PE_2-if config underlay-binding config fd PE_1-PE_2-FD
oc-if:interfaces interface PE_1-PE_2-if ipv4 addresses address 172.16.1.1 config ip 172.16.1.1 prefix-length 30
classifiers classifier CLASSIFIER-UNTAGGED filter-entry vtag-stack untagged-exclude-priority-tagged false
fps fp PE_1-PE_2-FP classifier-list-precedence 7 fd-name PE_1-PE_2-FD logical-port 1 mtu-size 2000 stats-collection on classifier-list CLASSIFIER-UNTAGGED
Walk the chain in the same order you built it: the FD should exist in
vpls mode, and the flow-point should show it sits on logical port 1,
references PE_1-PE_2-FD, and carries CLASSIFIER-UNTAGGED — that
three-way binding is what connects the wire to the routed interface.
Then in the IP interface state, both lb1 (172.16.0.1/32) and
PE_1-PE_2-if (172.16.1.1/30) should appear. Keep in mind PE_2 is
still an empty box: the /30 has no live peer yet, so don't expect
anything to answer a ping — that comes after the next task.
Verify (show mode) on PE_1:
show ip interfaces
Pass: Output contains lb1 and 172.16.0.1 and 32

Task 3: Configure IP address on port 1 of PE_2
Mirror Task 2 on PE_2 — the same object chain (forwarding domain,
loopback, IP interface, classifier, flow-point) with the addresses
shifted one:
lb1gets172.16.0.2/32- the link interface gets
172.16.1.2/30, the other usable host of the same /30
Configure (config mode) on PE_2:
fds fd PE_1-PE_2-FD mode vpls
oc-if:interfaces interface lb1 config name lb1 type loopback
oc-if:interfaces interface lb1 ipv4 addresses address 172.16.0.2 config ip 172.16.0.2 prefix-length 32
oc-if:interfaces interface PE_1-PE_2-if config mtu 1500 name PE_1-PE_2-if type ip
oc-if:interfaces interface PE_1-PE_2-if config underlay-binding config fd PE_1-PE_2-FD
oc-if:interfaces interface PE_1-PE_2-if ipv4 addresses address 172.16.1.2 config ip 172.16.1.2 prefix-length 30

Same checks as on PE_1, from PE_2's side: FD in vpls mode,
PE_1-PE_2-FP bound to the FD with CLASSIFIER-UNTAGGED, and IP
interfaces showing lb1 at 172.16.0.2/32 and PE_1-PE_2-if at
172.16.1.2/30. One naming detail worth internalizing as you read the
output: the link-scoped names (PE_1-PE_2-FD, PE_1-PE_2-FP,
PE_1-PE_2-if) are identical on both routers, because the scope is
the link, not the local node. Names are locally significant — nothing
on the wire carries them — but keeping them symmetric makes every later
lab's configs diffable side by side. Only lb1's address and the link
address differ. Once this passes, both ends of the /30 are configured
for the first time — the link is now a routable segment, which the next
task puts to the test.

Task 4: Confirm the IP configuration
Summary — No configuration here — this task is about reading state and understanding what routing exists without a routing protocol. Each router's table is populated only by virtue of its own interfaces.
Implementation — Nothing to build: inspect each PE's route table,
then ping across the /30. Expect a local route for the lb1 /32 and a
connected route for the /30 out PE_1-PE_2-if — that is enough for the
two routers to reach each other across the link, and nothing more.
In show ip routes on each PE, expect exactly the self-derived
entries: the router's own loopback via lb1 and the 172.16.1.0/30
subnet via PE_1-PE_2-if. The pings across the /30 should then succeed
at 100.00 percent — end-to-end proof that the classifier →
flow-point → forwarding-domain → IP interface chain forwards on both
ends. The remote loopback address is deliberately absent from these
checks: this lab configures no static or dynamic routes between
172.16.0.1/32 and 172.16.0.2/32, and testing them could follow the
management default route instead of the lab data path and produce a
misleading result. Making the loopbacks mutually reachable is exactly
what an IGP will do in a later lab.

Task 5: Apply IPv6 addresses
Summary — Dual-stack costs almost nothing in this model. The classifier, flow-point, and forwarding-domain are address-family-agnostic, so adding IPv6 is just more addresses on the existing interfaces — no new underlay objects.
Background — The plan mirrors IPv4's shape at IPv6 scale: a /128 on
the loopback plays the /32's role, and a /127 on the point-to-point
link is the IPv6 idiom for a two-host link, analogous to the /30. One
display behavior to expect: whatever case and compression you type
(FC00::600), SAOS 10x show output renders addresses lowercase and
fully expanded (fc00:0000:0000:0000:0000:0000:0000:0600) — the same
address in canonical form.
Implementation — On each PE, lb1 gets a /128 (FC00::1 on
PE_1, FC00::2 on PE_2) and PE_1-PE_2-if gets one host of the
/127 (FC00::600 and FC00::601).
Configure (config mode) on PE_1:
oc-if:interfaces interface lb1 ipv6 addresses address FC00::1 config ip FC00::1 prefix-length 128
oc-if:interfaces interface PE_1-PE_2-if ipv6 addresses address FC00::600 config ip FC00::600 prefix-length 127
Configure (config mode) on PE_2:
oc-if:interfaces interface lb1 ipv6 addresses address FC00::2 config ip FC00::2 prefix-length 128
oc-if:interfaces interface PE_1-PE_2-if ipv6 addresses address FC00::601 config ip FC00::601 prefix-length 127
show ipv6 interfaces on each PE should list lb1 with its fully
expanded /128 and PE_1-PE_2-if with its /127 — and this is where the
expansion rule bites: search the output for the expanded lowercase form,
not the FC00:: shorthand you typed. You will also see autoconfigured
link-local (fe80::) addresses alongside your global ones; those came
free with IPv6 enablement, not from your config.
Verify (show mode) on PE_1:
show ipv6 interfaces
Pass: Output contains lb1 and fc00:0000:0000:0000:0000:0000:0000:0001 and 128

Task 6: Confirm the IPv6 configuration
The IPv6 counterpart to Task 4 — prove the /127 forwards using the same
ping command (it accepts an IPv6 destination directly), under the
same routing reality: each router knows only its own /128 and the
connected /127.
Pinging the far side of the /127 (FC00::601 from PE_1, FC00::600
from PE_2) should return 100.00 percent success. As with IPv4, the
remote /128 loopbacks are deliberately absent from the checks — nothing
advertises them across the link without a routing protocol. When both
stacks ping cleanly, you have a verified dual-stack point-to-point
underlay and stable /32 + /128 router identities — the foundation the
rest of the series builds on.
Verify (show mode) on PE_1:
ping ip destination FC00::601 source FC00::600 repeat-count 3
Pass: Output contains 100.00 percent
Example output
Sending 3 ICMP Echos to FC00::601, timeout is 1 second
Codes:
'!' - Success, 'Q' - Request not sent, '.' - Timeout
Type 'Ctrl+C' to abort
! seq_num = 1 RTT = 2.37 ms TTL = 255
! seq_num = 2 RTT = 3.24 ms TTL = 255
! seq_num = 3 RTT = 3.85 ms TTL = 255
Success Rate is 100.00 percent (3/3)
Round-trip min/avg/max = 2.37/3.15/3.85
Verify (show mode) on PE_2:
ping ip destination FC00::600 source FC00::601 repeat-count 3
Pass: Output contains 100.00 percent
Example output
Sending 3 ICMP Echos to FC00::600, timeout is 1 second
Codes:
'!' - Success, 'Q' - Request not sent, '.' - Timeout
Type 'Ctrl+C' to abort
! seq_num = 1 RTT = 2.05 ms TTL = 255
! seq_num = 2 RTT = 4.05 ms TTL = 255
! seq_num = 3 RTT = 2.81 ms TTL = 255
Success Rate is 100.00 percent (3/3)
Round-trip min/avg/max = 2.05/2.97/4.05

G6: Task 6 — Confirm the IPv6 configuration
On PE_1, run:
ping ip destination FC00::601 source FC00::600 repeat-count 3
Pass: Output contains 100.00 percent
Example output
Sending 3 ICMP Echos to FC00::601, timeout is 1 second
Codes:
'!' - Success, 'Q' - Request not sent, '.' - Timeout
Type 'Ctrl+C' to abort
! seq_num = 1 RTT = 2.37 ms TTL = 255
! seq_num = 2 RTT = 3.24 ms TTL = 255
! seq_num = 3 RTT = 3.85 ms TTL = 255
Success Rate is 100.00 percent (3/3)
Round-trip min/avg/max = 2.37/3.15/3.85
On PE_2, run:
ping ip destination FC00::600 source FC00::601 repeat-count 3
Pass: Output contains 100.00 percent

Codes:
'!' - Success, 'Q' - Request not sent, '.' - Timeout
Type 'Ctrl+C' to abort
! seq_num = 1 RTT = 2.05 ms TTL = 255
! seq_num = 2 RTT = 4.05 ms TTL = 255
! seq_num = 3 RTT = 2.81 ms TTL = 255
Success Rate is 100.00 percent (3/3)
Round-trip min/avg/max = 2.05/2.97/4.05
