From: Joel Reymont on
I have a 877W with advanced IP services.

C870 Software (C870-ADVIPSERVICESK9-M), Version 12.4(15)T4, RELEASE
SOFTWARE (fc2)

I'm trying to make sure mDNS works on my wireless LAN but when I ping
from one Apple Mac, I get replies only from that Mac, whereas when I
ping from the router, I get replies from both Macs.

I have multicast routing enabled as well as pim sparse-dense-mode on
BVI1 (LAN-facing interface).

What do I need to do to make things work?

More importantly, how do I debug this problem?

When I enable packet debugging I don't even see the pings.

Thanks in advance, Joel
