I am configuring PIM-SM on an Extreme 460. One vlan on the 460 will have the multicast sources, a seoncd vlan is the connection to the rest of the network and the RP. ipforwarding is enabled OSPF is used for the routing protocol. My question is if I configure a static RP do I still need to configure a CBSR (candidate bootstrap router) ? If so should it be my 460 or the the RP?

Thanks Much!

I think, all you need is the following:

1st of all, create a policy with the following content:

entry mcast {

if {

} then {

nlri *your_mcast_address*;



Then configure mcast:

enable ipmcforwarding

conf pim add vlan *your mcast-sender vlan* sparse

conf pim add vlan *your transfer vlan* sparse

configure pim crp vlan " your transfer vlan " "your policy file" 0

configure pim cbsr vlan " your transfer vlan " *priority*

enable pim

Now - check the configuration with *sh pim rp-set* - the mcast-address entered in you policy-file must be in list.

best regards
