1. Single virtual MAC floats between cluster members, depending on which is Master; By Default.
2. Doesn't care about CoreXL or other physical differences between cluster members. But why would you have differently sized cluster members you cheap bast**d? :)
1. Decision is per interface.. Am I master or backup, one interface at a time; potential for split brain.
2. No Health checking of the cluster peer(s).
3. If same VRRP ID is used on all interfaces, potential to confuse switch when multiple firewall interfaces connected to same switch; multiple VLANs using same VRRP MAC.
4. Default VRRP MAC is still effected by IGMP, same as ClusterXL CCP multicast mode. VRRP hello packets are transmited using the VRRP MAC as the destination.
5. Only the Master node transmits Hello packets. No status of backup cluster member, VRRP interfaces must be monitored individually to discern if layer 2 connectivity problem exists on one or more interfaces.
