Not to steal your thread, but it's funny you mention all this. I just
configured multicast end-to-end on my Multi-VRF CE setup. First time ever
and what a nightmare, took me about a week. I downloaded a few Cisco Docs,
but they seem old. One specifically on multi-vrf multicast.
For some reason I couldn't get SSM working in my CORE, so I switched to PIM
Sparse and everything worked beautifully. I found this puzzling considering
all I thought you had to do was configure ip pim ssm on all the Core routers
with PIM sparse on the interconnections of course. According to the DOCs I
read I thought that was about all you had to do. My mdt default was
232.1.1.1.
I wouldn't mind getting my hand on some better DOCs or book recommendations
out there if there are any. I've checked out some Cisco Press Books and man
some of them bad boys are way overkill and a bit too technical at this point
for me. It would be nice to just get some nice explanations on the
mechanics of how this stuff is working in the background.
In any case, I feel your pain and look forward to doing SP after my R&S.
regards,
Dale
