Subject: ip multicast helper-map
Hi,
I'm having trouble with this, can anyone help me please.
I have 2 routers separated by a ppp link, I'm not saying it definitely
doesn't work but to be honest I just don't know. Can any suggest a good
way to troubleshoot this? Is it worth adding TCP to the access-lists
and telnetting to port 5575?
Here are the configs...
I've added show ip mroute output at the bottom though again is this even
any use in this scenario (Incoming interface: Null)?
As always, thank you in advance
Alex
