Enable VRRP for the backup system (IPv6)

An example of how to enable VRRP version 3 on the backup system for IPv6.

This task shows you how to enable VRRP version 3 on the dp0p1p1 interface of R2 and assigns dp0p1p1 to VRRP group 41.

The virtual address is the same as that for R1: 3003::300:2/64
R2 has the default priority (100), which is lower than the priority of R1 (150) — so R1 is the master and R2 is the backup under ordinary circumstances

Set the IPv6 address of the dp0p1p1 interface for R2.

vyatta@R2# set interfaces dataplane dp0p1p1 address 3003::300:3/64

Create the VRRP configuration node for dp0p1p1 of R2. This command enables VRRP on that interface.
```
vyatta@R2# set interfaces dataplane dp0p1p1 vrrp vrrp-group 41
```

Assign the VRRP group and protocol version.

vyatta@R2# set interfaces dataplane dp0p1p1 vrrp vrrp-group 41 version 3

Specify the virtual address of the VRRP group

vyatta@R2# set interfaces dataplane dp0p1p1 vrrp vrrp-group 41 virtual-address 3003::300:2

Enable RFC 3768-compliant MAC address handling and create the VRRP interface.

vyatta@R2# set interfaces dataplane dp0p1p1 vrrp vrrp-group 41 rfc-compatibility

Optional: Display the configuration.

vyatta@R2# show interfaces dataplane dp0p1p1 vrrp

vrrp {
     vrrp-group 41 {
         rfc-compatibility
         version 3
         virtual-address 3003::300:2
     }
 }

VRRP version 3 is enabled on the backup system for IPv6.
