Configuring Ip Multicasting Routing; Configuration For Ir1 - Extreme Networks ExtremeWare 7.2e Installation And User Manual

IP Multicast Routing
If a router does not support the mtrace functionality, it will silently drop the request packet and no
information will be returned. For this situation, you could send the trace with a small number of
maximum hops allowed, increasing the number of hops as the stream is traced.
The group IP address must be in the class-D multicast address space, but should not be in the multicast
control subnet range (224.0.0.x/24).
Use the following command to trace a multicast stream:
mtrace source <ip address> {destination <ip address>} {group <ip address>} {from <ip
address>} {gateway <ip address >} {timeout <seconds>} {maximum-hops <number>}

Configuring IP Multicasting Routing

To configure IP multicast routing, you must do the following:
1 Configure the system for IP unicast routing.
2 Enable multicast routing on the interface using the following command:
enable ipmcforwarding {vlan <vlan name>}
3 Enable PIM on all IP multicast routing interfaces using the following command:
configure pim add {vlan} [<vlan name>]
4 Enable PIM on the router using one of the following commands:
enable pim

Configuration for IR1

The router labeled IR1 has the following configuration:
configure vlan HQ_10_0_1 ipaddress 10.0.1.2 255.255.255.0
configure vlan HQ_10_0_2 ipaddress 10.0.2.2 255.255.255.0
configure ospf add vlan all
enable ipforwarding
enable ospf
enable ipmcforwarding
configure pim add vlan HQ_10_0_1
enable pim
The following example configures PIM-SM.
