Enabling IPv6 VRRP-Ev3

Before assigning a virtual IPv6 address to an IPv6 VRRPv3 group, you must configure IPv6 VRRP-Ev3 on a virtual ethernet interface and assign a VRRPv3 group to the device. The IPv6 VRRP-Ev3 session is enabled after the configuration of an IPv6 virtual IP address. The configuration example following after the individual steps represents all the steps together in order.

Enter the configure command to access the global configuration mode.
```
device# configure
```
To globally enable VRRP-Ev3, enter the ipv6 protocol vrrp-extended command.
```
device(config)# ipv6 protocol vrrp-extended
```
Enter the interface ve command with an associated virtual Ethernet (VE) interface number.
```
device(config)# interface ve 2019
```
In this example, virtual Ethernet (ve) configuration mode is entered and the interface is assigned with a VE number of 2019.
Enter an IPv6 address for the interface using the ipv6 address command.
```
device(config-if-ve-2019)# ipv6 address 2001:2019:8192::122/64
```
Enter the ipv6 vrrp-extended-group command with a number to assign a VRRP-E group to the device.
```
device(config-if-ve-2018)# ipv6 vrrp-extended-group 19
```
In this example, VRRP-Ev3 group configuration mode is entered.
Enter the virtual-ip command to assign a link-local virtual IPv6 address to a VRRPv3 group.
```
device(config-vrrp-extended-group-19)# virtual-ip fe80::2019:1
```
In this example, the IPv6 address of the virtual router is assigned to VRRP-Ev3 group 19 and the VRRP-Ev3 session is enabled.
Note
A maximum of two virtual IPv6 addresses can be configured on VRRP-Ev3 group. For VRRPv3, Extreme recommends using two IPv6 addresses; one link local address and one global address.
Enter the virtual-ip command to assign a virtual IPv6 address to a VRRPv3 group.
```
device(config-vrrp-extended-group-19)# virtual-ip 2001:2019:8192::1
```
In this example, a global IPv6 address is configured for the virtual router.

The following example shows how to enable a VRRP-E-v3 session by assigning a virtual IP address to an extended VRRP-E-v3 virtual group.

device# configure
device(config)# ipv6 protocol vrrp-extended
device(config)# interface ve 2019
device(config-if-ve-2019)# ipv6 address 2001:2019:8192::122/64
device(config-if-ve-2019)# ipv6 vrrp-extended-group 19
device(config-vrrp-extended-group-19)# virtual-ip fe80::2019:1
device(config-vrrp-extended-group-19)# virtual-ip 2001:2019:8192::1

After enabling a VRRP-Ev3 session, you may need to configure some optional parameters such as short-path forwarding for load-balancing or tracking an interface.
