Prerequisites for PIM-SM configuration

Before you can configure PIM-SM, you must prepare the switch as follows:
Step Action
1

Install the Advanced Routing software license.


Attention

If your Ethernet Routing Switch is running an Advanced License for a release prior to Release 6.0, to enable PIM-SM you must regenerate your license file from the Nortel web site and install the new license file on the switch.

2

Configure IP addresses on the VLAN interfaces on which you want to configure PIM-SM.
3

Enable a unicast protocol, either RIP or OSPF, globally and on the interfaces on which you want to configure PIM-SM.


Attention

PIM-SM requires a unicast protocol to multicast traffic within the network when performing the Reverse Path Forwarding (RPF) check. PIM-SM also uses the information from the unicast routing table to create and maintain the shared and shortest multicast tree. The unicast routing table must contain a route to every multicast source in the network, as well as routes to PIM entities such as the rendezvous points (RP) and bootstrap router (BSR).
