• 12.22.2025 - SR Linux
• 12.13.2025 - Playing with evpn and vxlan on ceos in ceos_lab/lab4
  • In the lab built out three flavors
    • static vxlan
    • ospf/bgp evpn
    • bgp/bgp evpn
  • Configs for these solutions can be found in the lab4/scripts/conf_bkup
• This repo will store store some labs as I mess around with this tool.
• Apple silicon has required me to go down this path.
• So far using srlinux, cEOS and FRR, (all freely available)
• With in couple of hours I've figured out how to use FRR in the way I was hoping to use cEOS.
• After some digging I found I was making too difficult to ssh into cEOS containerlab has that working out of the gates
• FRR is a much lighter performant image with my Mac M1.
• FRR/first_lab - basically just tested the routing and got ssh working
  • How to run multiple commands on frr router from shell
    • docker exec sh -c "vtysh -c '<>' -c '<>'"
    • docker exec clab-frr_lab-router1 sh -c "vtysh -c 'show version' -c 'show interface eth0' -c 'show ip route'"
  • Got ansible connected to FRR hosts can run show/config commands in ssh and non_ssh
• ceos_labs/lab1 - first functional arista lab on this platform
• ceos_labs/lab2 - More devices and eats more resources - if I reboot orbstack before running I have better success with it
• srlinux - work-in-progress
