Figure 92: Configuring Static Routes
In Figure 92 on page 436, PE 2 has external BGP connections to CE 3 and CE 4. PE
1 has an EBGP connection to CE 2. However, no BGP (or IGP) connection exists
between PE 1 and CE 1. The following example shows how to configure static routes
on VRF A for both prefixes in CE 1.
host1(config)# virtual-router pe1
host1:pe1(config)# ip vrf vpnA
host1:pe1(config-vrf)# ip route vrf vrfA 10.3.0.0 255.255.0.0 10.1.1.1
host1:pe1(config-vrf)# ip route vrf vrfA 10.12.0.0 255.255.0.0 10.1.1.1
ip route vrf
■
Use to add a static route to a VRF.
■
Example
host1:pe1(config-router-af)# ip route vrf vrfA 10.0.0.0 255.0.0.0 192.168.1.1
■
Use the no version to remove a static route from a VRF.
■
See ip route.
Configuring IGPs on the VRF
If you do not configure static routes on the VRF for each prefix in the associated
customer site, then you must configure an IGP on the VRF so that the VRF can learn
routes from customer sites.
Configuring the IGP in the VRF Context
After creating a VRF, you can access it as if it were a virtual router for the purpose
of configuring the IGP.
If you are in the context of the virtual router that has the VRF, you access the VRF
as follows:
host1(config)# virtual-router :vrfa
host1:default:vrfa(config)#
