When executing ipv6 ping from DCGW to VM and vice versa, ping is not working. Routes are showing up in quagga side, but quagga to Controller communication is not happening is what we suspect. Discussed with Karthikeyan and Sivakumar Perumalla regarding this. We need some help from VPN development team. Can any one from vpn team help us in this.?
Following investigations are done:
For DCGW side config: I have attached the configurations.
Below are the 2 loopback for ipv6 we configured in SER side:
interface lo2 loopback
ipv6 address 2001:db5::3:f816:3eff:fedb:1b40/128
!
interface lo3 loopback
ipv6 address 2001:db5:4:f816:3eff:fedb:1b40::/128
no logging console
these entries are showing up in quagga:
bgpd# show bgp ipv6 vpn all hidden

When we saw quagga logs, Vrf entry is getting deleted in the middle.
I request vpn team to look into this on high priority.
