If you established static routes on a PE router for each prefix in a particular customer site, you can configure BGP on the PE router to advertise these static routes to customer sites within the VPN with network commands.
- host1:vr1(config-router)#network 10.3.0.0
- host1:vr1(config-router)#network 10.12.0.0
In this example, both networks end on a classful boundary, eliminating the need to configure a network mask.
Alternatively, you can use the redistribute command to advertise the static routes as follows:
- host1:vr1(config-router)#redistribute static
See Configuring BGP Routing , for more information about advertising static routes.
