Phantom Router - Part 2

The animated TECHTip Tutorial is available here.

Phantom routers can exist throughout a network. The MAC [Media Access Control] address and the IP [Internet Protocol] addresses are passed among routers. This creates a virtual router called a Phantom router. It works like this:

One router is designated as the Active router and the other as the Phantom/Standby router. The Active router routes packets for the Phantom/Standby router.

Route Table/List updates are sent via HSRP [Hot Standby Routing Protocol] via Hello messages.

If the Phantom/Standby router does not receive Hello packets, it assumes that the Active router has failed and begins routing packets.

MHSRP is for multi-group (router) HSRP.
