Export Default Metric; Configuring Vrrp - Avaya G250 Administration

Configuring the router
The G250/G350 scheme for metric translation in route redistribution is as follows:
Static to RIP metric configurable (default 1)
●
OSPF internal metric N to RIP metric (default 1)
●
OSPF external type 1 metric N to RIP metric (default 1)
●
OSPF external type 2 metric N to RIP metric (default 1)
●
Static to OSPF external type 2, metric configurable (default 20)
●
RIP metric N to OSPF external type 2, metric (default 20)
●
Direct to OSPF external type 2, metric (default 20)
●
By default, the G250/G350 does not redistribute routes between OSPF and RIP. Redistribution
from one protocol to the other can be configured. Static routes are, by default, redistributed to
RIP and OSPF. The G250/G350 allows the user to globally disable redistribution of static routes
to RIP, and separately to globally disable redistribution of static routes to OSPF. In addition you
can configure, on a per static route basis, whether the route is to be redistributed to RIP and
OSPF, and what metric to use (in the range of 1-15). The default state is to allow the route to be
redistributed at metric 1. When static routes are redistributed to OSPF, they are always
redistributed as external type 2.
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.

Configuring 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.
