Alcatel-Lucent OmniSwitch AOS Release 7 - Vrrpv3 Tracking Example

Configuring VRRP VRRPv3 Application Example
OmniSwitch AOS Release 7 Network Configuration Guide March 2011 page 18-31
Note. The same VRRPv3 configuration must be set up on each switch. The VRRPv3 router that contains,
or owns, the IPv6 address will automatically become the master for that virtual router. If the IPv6 address
is a virtual address, the virtual router with the highest priority will become the master router.
In this scenario, the master of VRID 1 will respond to neighbor solicitation with a neighbor advertisement
for IPv6 address A using the virtual router MAC address for VRID 1 (00:00:5E:00:02:01). OmniSwitch
10K 1 is the master for VRID 1 since it contains the physical interface to which
213:100:1::56s
assigned. If OmniSwitch 10K A should become unavailable, OmniSwitch 10K B will become master for
VRID 1.
In the same way, the master of VRID 2 will respond to neighbor solicitation for IPv6 address B using the
virtual router MAC address for VRID 2 (00:00:5E:00:02:02). OmniSwitch 10K B is the master for VRID
2 since it contains the physical interface to which
213:100:1::57 is assigned. If OmniSwitch 10K B
should become unavailable, OmniSwitch 10K A will become master for
213:100:1::57. This configura-
tion provides uninterrupted service for the end hosts.
VRRPv3 Tracking Example
The figure below shows two VRRPv3 routers with two virtual routers backing up one IPv6 address on
each VRRPv3 router respectively. Virtual router 1 serves as the default gateway on OmniSwitch 10K A
for clients 1 and 2 through IPv6 address
213:100:1::56. For example, if the port that provides access to
the Internet on OmniSwitch 10K A fails, virtual router 1 will continue to be the default router for clients 1
and 2, but clients 1 and 2 will not be able to access the Internet.
