Sparse Mode With A Single Static Rp Example - Cisco Catalyst 4500 Series Configuration Manual

Chapter 35 Configuring IP Multicast
interfaces are used to allow this configuration and the addresses of these interfaces must be routed
throughout the PIM domain so that the other routers in the PIM domain can receive Auto-RP
announcements and communicate with the RP:
ip multicast-routing !Enable IP multicast routing
ip pim bidir-enable
!
interface loopback 0
description One Loopback address for this routers Bidir Mode RP function
ip address 10.0.1.1 255.255.255.0
ip pim sparse-dense-mode
!
interface loopback 1
description One Loopback address for this routers Sparse Mode RP function
ip address 10.0.2.1 255.255.255.0
ip pim sparse-dense-mode
ip pim send-rp-announce Loopback0 scope 10 group-list 45 bidir
ip pim send-rp-announce Loopback1 scope 10 group-list 46
ip pim send-rp-discovery scope 10
access-list 45 permit 224.0.0.0 0.255.255.255
access-list 45 permit 227.0.0.0 0.255.255.255
access-list 45 deny
access-list 46 permit 226.0.0.0 0.255.255.255

Sparse Mode with a Single Static RP Example

The following example sets the PIM RP address to 192.168.1.1 for all multicast groups and defines all
groups to operate in sparse mode:
ip multicast-routing
interface ethernet 1
ip pim sparse-mode
ip pim rp-address 192.168.1.1
no ip pim dm-fallback
The same RP cannot be used for both bidirectional and sparse mode groups.
Note
The following example sets the PIM RP address to 172.16.1.1 for the multicast group 225.2.2.2 only:
access list 1 225.2.2.2 0.0.0.0
ip pim rp-address 172.17.1.1
Sparse Mode with Auto-RP: Example
The following example configures sparse mode with Auto-RP:
ip multicast-routing
ip pim autorp listener
ip pim send-rp-announce Loopback0 scope 16 group-list 1
ip pim send-rp-discovery Loopback1 scope 16
no ip pim dm-fallback
access-list 1 permit 239.254.2.0 0.0.0.255
access-list 1 permit 239.254.3.0 0.0.0.255
.
.
access-list 10 permit 224.0.1.39
access-list 10 permit 224.0.1.40
access-list 10 permit 239.254.2.0 0.0.0.255
access-list 10 permit 239.254.3.0 0.0.0.255
