hiya guys,

i have a full mesh ceph setup on 200gb nics

but i would like to create a second full mesh setup for my cluster to seperate cluster traffic
i have another 2x 100gb nics spare in each node interfaces enp4s0f0np0 and enp4s0f1np1
id like this to be the second seperate routed full mesh

but i cannot get it working for the life of me, and it keeps showing up as connected over the same first network ie.10.15.15.50
i know i must be doing something silly or wrong

Hello!

Curious if you ever were able to get this to work and if so, how you did it. If you were not able to get it to work, did you happen try to update the config for Ceph to make sure the public and cluster networks were the two different IPs as you had set them up in frr?
