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
  1. Set the IPv6 address of the dp0p1p1 interface for R2.
    vyatta@R2# set interfaces dataplane dp0p1p1 address 3003::300:3/64
  2. 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
  3. Assign the VRRP group and protocol version.
    vyatta@R2# set interfaces dataplane dp0p1p1 vrrp vrrp-group 41 version 3
    
  4. Specify the virtual address of the VRRP group
    vyatta@R2# set interfaces dataplane dp0p1p1 vrrp vrrp-group 41 virtual-address 3003::300:2
  5. Enable RFC 3768-compliant MAC address handling and create the VRRP interface.
    vyatta@R2# set interfaces dataplane dp0p1p1 vrrp vrrp-group 41 rfc-compatibility
  6. Commit the configuration.
    vyatta@R2# commit
  7. 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.
