Chapter 38 Configuring IP Unicast Routing
Configuring Multi-VRF CE
For more information about configuring a multicast within a Multi-VRF CE, see the Cisco IOS IP
Multicast Configuration Guide, Release 12.4.
Configuring a VPN Routing Session
Routing within the VPN can be configured with any supported routing protocol (RIP, OSPF, EIGRP, or
BGP) or with static routing. The configuration shown here is for OSPF, but the process is the same for
other protocols.
Note To configure an EIGRP routing process to run within a VRF instance, you must configure an
autonomous-system number by entering the autonomous-system autonomous-system-number
address-family configuration mode command.
Beginning in privileged EXEC mode, follow these steps to configure OSPF in the VPN:
Step 5 route-target {export | import | both}
route-target-ext-community Create a list of import, export, or import and export route target
communities for the specified VRF. Enter either an autonomous-system
number and an arbitrary number (nnn:y) or an IP address and an
arbitrary number (A.B.C.D:y). The route-target-ext-community should
be the same as the route-distinguisher entered in Step 4.
Step 6 import map route-map (Optional) Associate a route map with the VRF.
Step 7 ip multicast-routing vrf vrf-name
distributed (Optional) Enable global multicast routing for VRF table.
Step 8 interface interface-id Specify the Layer 3 interface to be associated with the VRF, and enter
interface configuration mode. The interface can be a routed port or an
SVI.
Step 9 ip vrf forwarding vrf-name Associate the VRF with the Layer 3 interface.
Step 10 ip address ip-address mask Configure the IP address for the Layer 3 interface.
Step 11 ip pim sparse-dense mode Enable PIM on the VRF-associated Layer 3 interface.
Step 12 end Return to privileged EXEC mode.
Step 13 show ip vrf [brief | detail | interfaces]
[vrf-name] Verify the configuration. Display information about the configured
VRFs.
Step 14 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 router ospf process-id vrf vrf-name Enable OSPF routing, specify a VPN forwarding table,
and enter router configuration mode.
Step 3 log-adjacency-changes (Optional) Log changes in the adjacency state. This is the
default state.
Step 4 redistribute bgp
autonomous-system-number subnets Set the switch to redistribute information from the BGP
network to the OSPF network.
