16.1.11 Configuring IPv4 PIM-SM in VRF [SL-L3A]

Points to note

To use IPv4 PIM-SM in a VRF, configure the IPv4 multicast routing functionality for the VRF, and configure IPv4 PIM-SM (sparse mode) on the interface of the VRF.

The settings for IPv4 PIM-SM (sparse mode) are specified in interface configuration mode. The following figure shows an example of a IPv4 PIM-SM configuration in which VRF 10 is associated with VPN 2 and IP of VLAN 20 interfaces of VRF 10 is 192.168.20.1/24.
