NOTE
It is recommended that you configure the same device as both the BSR and the RP.
IPv6 PIM-Sparse mode
To configure a device for IPv6 PIM Sparse, perform the following tasks:
• Identify the Layer 3 switch as a candidate sparse Rendezvous Point (RP), if applicable.
• Specify the IPv6 address of the RP (to configure statically).
The following example enables IPv6 PIM-SM routing. Enter the following command at the
configuration level to enable IPv6 PIM-SM globally.
device(config)# ipv6 router pim
device(config-ipv6-pim-router)#
To enable IPv6 PIM Sparse mode on an interface, enter commands such as the following.
device(config)# interface ethernet 2/2
device(config-if-e10000-2/2)# ipv6 address a000:1111::1/64
device(config-if-e10000-2/2)# ipv6 pim-sparse
Syntax: [no] ipv6 pim-sparse
Use the no option to remove IPv6 PIM sparse configuration from the interface.
The commands in this example add an IPv6 interface to port 2/2, then enable IPv6 PIM Sparse on the
interface.
Configuring IPv6 PIM-SM on a virtual routing interface
You can enable IPv6 PIM-SM on a virtual routing interface by entering commands such as the
following.
device(config)# interface ve 15
device(config-vif-15)# ipv6 address a000:1111::1/64
device(config-vif-15)# ipv6 pim-sparse
Enabling IPv6 PIM-SM for a specified VRF
To enable IPv6 PIM-SM for the VRF named "blue", create the VRF named "blue", enable it for IPv6
routing, and then enable IPv6 PIM-SM for the VRF, as shown in the following example.
device(config)# vrf blue
device(config-vrf-blue)# rd 11:1
device(config-vrf-blue)# address-family ipv6
device(config-vrf-blue-ipv6)# router pim
device(config-pim-router)# ipv6 router pim vrf blue
device(config-ipv6-pim-router-vrf-blue)
Syntax: [no] ipv6 router pim [ vrf vrf-name ]
The vrf parameter allows you to configure IPv6 PIM-SM on the virtual routing instance (VRF) specified
by the vrf-name variable. All PIM parameters available for the default router instance are configurable
for a VRF-based PIM instance.
Use the no option to remove all configuration for PIM multicast on the specified VRF.
