Configuring IP Multicast Routing
Configuring IP Multicast Routing
DETAILED STEPS
Command Purpose
1. show running-config Verify that a default RP is already configured on all PIM devices
and the RP in the sparse-mode network. It was previously
configured with the ip pim rp-address global configuration
command.
This step is not required for spare-dense-mode environments.
The selected RP should have good connectivity and be available
across the network. Use this RP for the global groups (for
example 224.x.x.x and other global groups). Do not reconfigure
the group address range that this RP serves. RPs dynamically
discovered through Auto-RP take precedence over statically
configured RPs. Assume that it is desirable to use a second RP
for the local groups.
2. configure terminal Enter global configuration mode.
3. ip pim send-rp-announce
interface-id scope ttl group-list
access-list-number interval
seconds
Configure another PIM device to be the candidate RP for local
groups.
 For interface-id, enter the interface type and number that
identifies the RP address. Valid interfaces include physical
ports, port channels, and VLANs.
 For scope ttl, specify the time-to-live value in hops. Enter a
hop count that is high enough so that the RP-announce
messages reach all mapping agents in the network. There
is no default setting. The range is 1 to 255.
 For group-list access-list-number, enter an IP standard
access list number from 1 to 99. If no access list is
configured, the RP is used for all groups.
 For interval seconds, specify how often the announcement
messages must be sent. The default is 60 seconds. The
range is 1 to 16383.
4. access-list access-list-number
{deny | permit} source
[source-wildcard]
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 3.
 The deny keyword denies access if the conditions are
matched. The permit keyword permits access if the
conditions are matched.
 For source, enter the multicast group address range for
which the RP should be used.
 (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.
