multicast routing don't work 1

[summerdike]

Want to have multicast routing on Vlan23. Here's some troubleshooting command printouts:

demoswitch1#mrinfo

Why would you want to enable multicasting on a single VLAN? The whole point of multicast routing is to ROUTE multicast traffic between IP networks. This isn't applicable to a multicasting on a single VLAN/Network.

Can you explain a little more about your topology and what you are trying to achieve?

I have Ip phone (Ericsson) that registers to Gatekeeper (PBX, MD110) automatically using multicast discovery request through address 224.0.1.41.

What VLAN is the MD110 on, what is its IP address? You should see a source of this group being the MD110 IP Address (the Gatekeeper interface).

You ar nothing but right.
I misconfigured some parameters that have nothing to do with multicasting (in phone & pbx) as a result of which the regsitration failed.

Indeed registration is done automatically within the Vlan without any multicast routing.

TY.
