Configuring IP Multicast Routing
Configuring IP Multicast Routing
BEFORE YOU BEGIN
Enable PIM on the interface using the ip pim command as described in the
page 689.
DETAILED STEPS
Command
1. configure terminal
2. ip pim rp-candidate interface-id
[group-list access-list-number]
3. access-list access-list-number
{deny | permit} source
[source-wildcard]
4. end
5. show running-config
6. copy running-config
startup-config
To remove this device as a candidate RP, use the no ip pim rp-candidate interface-id global configuration command.
EXAMPLE
This example shows how to configure the switch to advertise itself as a candidate RP to the BSR in its PIM domain.
Standard access list number 4 specifies the group prefix associated with the RP that has the address identified by a port.
That RP is responsible for the groups with the prefix 239.
Switch(config)# ip pim rp-candidate gigabitethernet0/2 group-list 4
Switch(config)# access-list 4 permit 239.0.0.0 0.255.255.255
Purpose
Enter global configuration mode.
Configure your switch to be a candidate RP.

For interface-id, specify the interface whose associated IP
address is advertised as a candidate RP address. Valid
interfaces include physical ports, port channels, and
VLANs.

(Optional) For group-list access-list-number, enter an IP
standard access list number from 1 to 99. If no group-list
is specified, the switch is a candidate RP for all groups.
Create a standard access list, repeating the command as many
times as necessary.

For access-list-number, enter the access list number
specified in Step 2.

The deny keyword denies access if the conditions are
matched. The permit keyword permits access if the
conditions are matched.

For source, enter the number of the network or host from
which the packet is being sent.

(Optional) For source-wildcard, enter the wildcard bits in
dotted decimal notation to be applied to the source. Place
ones in the bit positions that you want to ignore.
Recall that the access list is always terminated by an implicit
deny statement for everything.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
