Configuring Multicast Vrfs; Configuring A Vpn Routing Session - Cisco Catalyst 3560-X Software Configuration Manual

Chapter 1 Configuring IP Unicast Routing

Configuring Multicast VRFs

Beginning in privileged EXEC mode, follow these steps to configure a multicast within a VRF table. For
complete syntax and usage information for the commands, see the switch command reference for this
release and the Cisco IOS Switching Services Command Reference, Release 12.4.

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.
To configure an EIGRP routing process to run within a VRF instance, you must configure an
Note
autonomous-system number by entering the autonomous-system autonomous-system-number
address-family configuration mode command.
OL-25303-03
Purpose
Enter global configuration mode.
Enable IP routing mode.
Name the VRF, and enter VRF configuration mode.
Create a VRF table by specifying a route distinguisher. Enter either an
AS number and an arbitrary number (xxx:y) or an IP address and an
arbitrary number (A.B.C.D:y)
Create a list of import, export, or import and export route target
communities for the specified VRF. Enter either an AS system number
and an arbitrary number (xxx: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.
(Optional) Associate a route map with the VRF.
(Optional) Enable global multicast routing for VRF table.
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.
Associate the VRF with the Layer 3 interface.
Configure IP address for the Layer 3 interface.
Enable PIM on the VRF-associated Layer 3 interface.
Return to privileged EXEC mode.
Verify the configuration. Display information about the configured
VRFs.
(Optional) Save your entries in the configuration file.
