VRRP master-master state replication

VRRP master-master state replication

Control packets are not being exchanged between master and backup because of faulty status. This article describes how to replicate a master/master state in VRRP.

Control packets are not exchanging between master and backup because the current state is master/master, probably due to a mistaken firewall filter or packet loss among service providers, or WEDGE condition in PFE.

Here is how to replicate the master/master problem state. This KB articles uses a firewall filter instead of WEDGE condition for the example.

Topology

Normal state

Configuration

Firewall activation to make WEDGE

Change priority on backup router

Create master/master state

When a master/master state is encountered, check to see if the control packets are being correctly exchanged.
