I'm trying to do a basic config for multicast. I'm configuring this on a Catalyst 4507. I'm going with a shared tree, sparse-dense on the vlan interfaces, and configuring a single static RP. There will be other layer 3 switches involved at some point, all on the same physical network, just with different vlans.
I'm looking at the software config guide for 12.2(44)SG and there is a command for setting a static rp-address(ip pim rp-address xxx.xxx.xxx.xxx). My question is, I have no idea what that RP address is. Since that core switch is the RP, do I config it as:
ip pim rp-address 127.0.0.1
If so, what about the other layer 3 switches that are routing traffic? Do I point the RP command towards the management vlan ip for the main core switch? The documentation isn't very clear about this.
Thanks in advance!
