+
+This lab demonstrates a simple iBGP peering scenario between Nokia SR Linux and Arista cEOS.
+
+#### Configuration
+Once the lab is deployed with containerlab, use the following configuration instructions to make interfaces configuration and enable BGP on both nodes.
+
+=== "srl"
+    Get into SR Linux CLI with `docker exec -it clab-srlceos01-srl sr_cli` and start configuration
+    ```bash
+    # enter candidate datastore
+    enter candidate
+
+    # configure loopback and data interfaces
+    set / interface ethernet-1/1 admin-state enable
+    set / interface ethernet-1/1 subinterface 0 admin-state enable
+    set / interface ethernet-1/1 subinterface 0 ipv4 address 192.168.1.1/24
+
+    set / interface lo0 subinterface 0 admin-state enable
+    set / interface lo0 subinterface 0 ipv4 address 10.10.10.1/32
+
+    # configure BGP
+    set / network-instance default router-id 10.10.10.1
+    set / network-instance default interface ethernet-1/1.0
+    set / network-instance default interface lo0.0
+
+    set / network-instance default protocols ospf instance main admin-state enable
+    set / network-instance default protocols ospf instance main version ospf-v2
+    set / network-instance default protocols ospf instance main area 0.0.0.0 interface ethernet-1/1.0 interface-type point-to-point
+    set / network-instance default protocols ospf instance main area 0.0.0.0 interface ethernet-1/1.0
+
+    # commit config
+    commit now
+    ```
+=== "ceos"
+    cRPD configuration needs to be done both from the container process, as well as within the CLI.  
+    First attach to the container process `bash` shell and configure interfaces: `docker exec -it clab-srlceos01-crpd bash`
+    ```bash
+    # configure linux interfaces
+    ip addr add 192.168.1.2/24 dev eth1
+    ip addr add 10.10.10.2/32 dev lo
+    ```
+    Then launch the CLI and continue configuration `docker exec -it clab-srlceos01-crpd cli`:
+    ```bash
+    # enter configuration mode
+    configure
+    set routing-options router-id 10.10.10.2
+
+    set protocols ospf area 0.0.0.0 interface eth1 interface-type p2p
+    set protocols ospf area 0.0.0.0 interface lo.0 interface-type nbma
+
+    # commit configuration
+    commit
+    ```
