Configuring IPv6 VRRP-E Load-balancing using Short-path Forwarding

VRRP-E traffic can be load-balanced using short-path forwarding on the backup devices.

Before configuring VRRP-E load-balancing, VRRP-E must be configured on all devices in the VRRP-E session.

Perform this task on all backup VRRP-E Layer 3 devices to allow load sharing within a VRRP extended group.
  1. Use the configure terminal command to enter global configuration mode.
    device# configure terminal
  2. Globally enable VRRP-E.
    device(config)# ipv6 router vrrp-extended
  3. Enter the interface ve command with an associated VLAN number.
    device(config)# interface ve 10
    In this example, virtual Ethernet (ve) configuration mode is entered and the interface is assigned a VLAN number of 10.
  4. Enter the ipv6 vrrp-extended vrid command with a number to assign a VRRP-E virtual router ID to the device.
    device(config-vif-10)# ipv6 vrrp-extended vrid 100
    In this example, VRRP-E group configuration mode is entered.
  5. Enter the backup command to configure the device as a VRRP-E backup device.
    device(config-vif-10-vrid-100)# backup
  6. Enter the short-path-forwarding command to configure the backup VRRP-E device as an alternate path with a specified priority.
    device(config-vif-10-vrid-100)# short-path-forwarding

In the following example, short-path forwarding is configured on a backup IPv6 VRRP-E device.

device# configure terminal
device(config)# ipv6 router vrrp-extended
device(config)# interface ve 10
device(config-vif-10)# ipv6 vrrp-extended vrid 100
device(config-vif-10-vrid-100)# backup
device(config-vif-10-vrid-100)# short-path-forwarding
