Ospf And Bgp Route Distribution; Configuration - Avaya 8000 Technical Configuration Manual

redistribute all "direct" (i.e. locally connected) routes but do not wish to advertise the IP prefixes of certain
interfaces.
Also, the BGP "metric" attribute associated with each prefix, also known as MED, may also be set. Note
that if the metric is also set via a route-policy, the route-policy specified metric takes precedence.
When the prefix originated by the "redistribute" command is advertised via BGP its Route Origin attribute
is set to "INC", or incomplete. When BGP selects the best path to a given destination a route with origin
"IGP" takes priority over a route with origin "INC". The following is an example of routes imported on an
ERS 8000 after BGP direct redistribute has been enable on a peer ERS 8000. Notice the Route Origin is
"INC".

6.2 OSPF and BGP Route Distribution

This section describes commands you use to create OSPF and BGP route distribution. The commands
used are in reference to Figure 1 used in Section 3.1 above using 8008.
6.2.1

Configuration

To create OSPF and BGP route distribution policies, complete the following steps:
6.2.1.1 Configure OSPF on 8008
Configure 8008 as an OSPF ASBR and enable OSPF
8008:1(config)#router ospf
8008:5(config-ospf)#as-boundary-router enable
8008:5(config-ospf)#exit
8008:5(config)#router ospf enable

The ERS 8000 must be configured as an OSPF Autonomous System Border Router
(ASBR) in order to support other routing protocols other than OSPF.
