VLAGs with VRRP
Task 1: Configure VLAG Peer 1
1. Configure VLAG tier ID
2. Configure appropriate routing.
3. Configure a server‐facing interface.

G8264 Application Guide for ENOS 8.4
Note: In a multi‐layer environment, configure VRRP separately for each layer. We
recommend that you configure VRRP only on the tier with uplinks. See
"Configuring VLAGs in Multiple Layers" on page
VRRP (see Chapter
39, "Virtual Router Redundancy Protocol") can be used in
conjunction with VLAGs and LACP‐capable devices to provide seamless
redundancy.

Note: Before enabling VLAG, you must configure the VLAG tier ID and ISL
portchannel.
RS G8264(config)# vlag tierid 10
RS G8264(config)# router ospf
RS G8264(configrouterospf)# area 1 areaid 0.0.0.1
RS G8264(configrouterospf)# enable
RS G8264(configrouterospf)# exit
Although OSPF is used in this example, static routing could also be deployed. For
more information, see Chapter 35, "Open Shortest Path First" or Chapter 26,
"Basic IP Routing."
RS G8264(config)# interface ip 3
RS G8264(configipif)# ip address 10.0.1.10 255.255.255.0
RS G8264(configipif)# vlan 100
RS G8264(configipif)# exit
