ASR1000 Multicast issue

[DaveJ006]

Having an issue getting Multicast through the Cisco ASR1000.

Simple setup: VM Linux PC 1 & 2, Cisco ASR100 router in the middle (Router on a stick).

Can ping from PC 1&2 to CSR, can ping to/from PC1 & PC2. So generally, looks good.

Have enabled Multicast, and Dense mode on the 2 sub Interfaces, interval query 125 also on interfaces (I have tried with interval Quarry on and off.

Have placed multicast static route on each PC.

When I look at the debug it looks like 1 side is not joining the group.

I suspect its something in the VM setup. Have gone over and over this – now hitting a wall :(

Any ideas appreciated please?

Thank you

I found the issues.

2 issues with test tool - Iperf….

1) needed to add a TTL to the Multicast else it was dropping/not crossing the router with a default TTL of 1...

2) Iperf required the Server (listening side) to have -B 225.0.0.x so it knows to listen to/join group.
