[c-nsp] XR 12000/GSR - 4.2.3 VRRP IPv6 Global virtual address.

[Danny Pinto]

Thanks I able to get VRRP working on v6 between two  XR 12K boxes.

But when I try to get VRRP working between a XR12K and  JunOS on MX . v4 VRRP works fine.

VRRP v6 does not come up , getting some checksum errors on the debug for v6 and both the boxes are becoming masters ! Any clue ?

Anything needs to be done to get VRRP v6 working between XR and JunOS. ? below is configuration & logs .
