VLT Proxy Gateway Peering Issues S4048-ON OS9.10
Hello,
I am trying to learn how to configure VLT and I am unable to get the Proxy to peer successfully via OSPF dynamically across the 2 VLT domains. I have read the whitepapers but it looks like I have configured everything correctly. What am I doing wrong? I am also unable to ping vlans going from VLT domain 1 to 2. The proxy port channel peer (in this case Port Channel 30) shows its local status as up but the peer status as down. Here are the running configs from 2 of the 4 since they are similar. Thank You
