we're currently planning to redesign our datacenter network with cumulus enabled switches in a leaf-spine architecture.
At the moment we're having a test-setup with cumulus vx vms (2 spines, 2 leafs) and two guest-vms that should communicate through a custom vxlan.
For this setup I grabbed the quagga deamon in version 1.0.0+cl3u11 and deployed it to the guest-vms.
I configured an unnumbered eBGP setup and as far as I can see the BGP sessions are properly established for ipv4, ipv6 and evpn.
I created two vxlan interfaces, one on each guest, and assigned them to a bridge br0. I assigned an ip address on both systems and expected to be able to ping each other host.
Unfortunately the pings are not successful. I see the requests arrive on the other host and also the replies going out but they do not reach the first host.
I created a github repository with configs and cl-support files. You can find it here:
Could you give me some markers what am I missing here?
