Configuring IP Multicast Routing

IP Multicast Configuration Examples

PIM Dense Mode State Refresh Example

The following example shows a PIM router that is originating, processing, and forwarding PIM Dense Mode State Refresh control messages on Fast Ethernet interface 0/1 every 60 seconds:

ip multicast-routing

interface FastEthernet0/1

ip address 172.16.8.1 255.255.255.0

ip pim state-refresh origination-interval 60 ip pim dense-mode

The following example shows a PIM router that is processing and forwarding PIM Dense Mode State Refresh control messages and not originating messages on Fast Ethernet interface 1/1:

ip multicast-routing

interface FastEthernet1/1

ip address 172.16.7.3 255.255.255.0 ip pim dense-mode

Functional Address for IP Multicast over Token Ring LAN Example

In the following example, any IP multicast packets going out Token Ring interface 0 are mapped to MAC address 0xc000.0004.0000:

interface token 0

ip address 1.1.1.1 255.255.255.0 ip pim dense-mode

ip multicast use-functional
