  • The VRRP packet is the same for IPv6 as for IPv4, except that it is encapsulated in IPv6 instead of IPv4. – Ron Maupin Mar 14 at 17:11
  • Look what I found with 2 seconds of Google searching: support.huawei.com/enterprise/it/doc/EDOC1000178318/6e22bde4/… – Ron Trunk Mar 14 at 17:13
  • Thanks, but i am in need of a packet capture for IPv6 VRRP, to test .Can you help. – Abhishek parikshya Mar 14 at 17:19
  • If you need something like that, then, unfortunately, your question is off-topic here. You will need to mirror on the switch between the routers for the VLAN(s) for which you want to capture. – Ron Maupin Mar 14 at 17:45

The VRRPv3 packet format is exactly the same for IPv4 and IPv6. The VRRP packet is encapsulated in either IPv4 or IPv6, so the IP header will vary per version, but the rest of the packet is the same.

5.1. VRRP Packet Format

This section defines the format of the VRRP packet and the relevant fields in the IP header.
