4.12.4 Example for Configuring a VRRP Backup Group on VLANIF
Interfaces
In this example, user packets are sent to a UPE that is dual-homed to two directly connected
NPEs. The three devices form a ring network. A VRRP backup group is configured on VLANIF
interfaces of these NPEs to implement device backup. Broadcasting VRRP packets on the ring
network causes broadcast storms. A ring network protocol needs to be configured to prevent this
problem. In this example, the Multiple Spanning Tree Protocol (MSTP) is used.
Networking Requirements
On the network shown in
forming a ring network. VRRP backup group 1 is configured on VLANIF 10 of NPE1.
NPE1 is the master device and periodically broadcasts VRRP packets through VLAN 10's
member interfaces to inform NPE2 that NPE1 is working properly. VLAN 10's member
interfaces include GE1/0/1 and Eth-Trunk1 members GE 2/0/0 and GE 2/0/1. The deployment
causes broadcast storms on the ring network.
A ring network protocol can be configured to break loops and prevent broadcast storms.
