VRRP Master IP is not pingable by default. Some platforms allow you to configure ICMP reply for VIP.As soon as ARP cache shows VIP to VMAC mapping you are good to go.The hosts go through the VIP, not to the VIP.

CRS1000v works, but currently, I am using XRv9000 as spines to be able to filter MAC address routes.I think I had duplicated OSPF RID due to VTEPs or mismatching OSPF link subnets.

I have found the answers to my issues. Rule1: Always use a dedicated VMware vSwitch which allows all VLANs (4095) -> Peer-link can pass VLANs, Vlanif backup works with automatic VXLAN encapsulation. No extra command is needed, just enable PIM and IGP...

Hello, Actually I solved the problem that OSPF did not come up on SVI and upgraded to NX-OSv 9.3.1.I have just realized that the peer-link must be a vSW with all VLANs enabled and finally were able to test if traffic can be rerouted over the peer-lin...
