Problem:
Containerlab returns a similar error:
Error: eth0 interface name is not allowed for R2 node when network mode is not set to none
Solution:
In the .yml file in the node section indicating the topology error specify:
network-mode: none
Example:
topology:
kinds:
linux:
image: quay.io/frrouting/frr:8.4.1
nodes:
R1:
kind: linux
image: quay.io/frrouting/frr:8.4.1
network-mode: none
Rerun the topology with clab dep -t file.yml and that's it!
Luck.
Step 1: Install Canonical Multipass your MAC
$brew install multipass
Step 2: Install the VM called docker
$multipass launch docker --name mydocker
Step 3: Connect to the new VM
$multipass shell mydocker
Step 4: Inside the VM install ContainerLab
$sudo su
#bash -c "$(curl -sL https://get.containerlab.dev)"
Let's try this simple back2back topology of two Linux computers with FRR
-- 2-frr-back2back.yml --
name: ipv6-ws
topology:
kinds:
linux:
image: ghcr.io/hellt/network-multitool
do not give:
ROUTERS ###
A1:
kind: linux
image: quay.io/frrouting/frr:8.4.1
exec:
- "sysctl -w net.ipv6.conf.all.forwarding=1"
- "ip address add dev eth1 2001:db8:ffab::1/64"
A2:
kind: linux
image: quay.io/frrouting/frr:8.4.1
exec:
- "ip address add dev eth1 2001:db8:ffab::2/64"
- "sysctl -w net.ipv6.conf.all.forwarding=1"
links:
- endpoints: ["R1:eth1", "R2:eth1"]
--- yml --
Step 5: Let's build the topology with clab:
clab dep -t 2-frr-back2back.yml
Step 6: finally we are going to connect to one of the VMs inside ContainerLAB
docker exec -i -t clab-ipv6-ws-R2 bash
