Configuring the router
Use the redistribute command in the Router RIP context to configure route redistribution
into RIP. Use the redistribute command in the Router OSPF context to configure route
redistribution into OSPF.

Export default metric

The Avaya G250/G350 Media Gateway enables you to configure the metric to be used in
updates that are redistributed from one routing protocol to another.
In RIP, the default is 1 and the maximum value is 16. In OSPF, the default is 20.
Set this value before redistribution using the default-metric command from within the
Router RIP or Router OSPF contexts. This value is used for all types of redistributed routes,
regardless of the protocol from which the route was learned.

Overview of VRRP
Virtual Router Redundancy Protocol (VRRP) is an IETF protocol designed to support
redundancy of routers on the LAN and load balancing of traffic. VRRP is open to host stations,
making it an ideal option when redundancy, load balancing, and ease of configuration are
required.
The concept underlying VRRP is that a router can backup other routers, in addition to
performing its primary routing functions. This redundancy is achieved by introducing the
concept of a virtual router. A virtual router is a routing entity associated with multiple physical
routers. One of the physical routers with which the virtual router is associated performs the
routing functions. This router is known as the master router. For each virtual router, VRRP
selects a master router. If the selected master router fails, another router is selected as master
router.
