Subject: RE: RPF lookup failed stuff with auto rp
Hi,
I'm still struggling with the multicasting topics, doesn't seems to have
much practise in bootcamp ot fatkid lab (normally dense mode), is there any
good documents that I can find in order to have good understanding on pim
spase mode (static rp or auto-rp) besides the Multicast Tech Tips on Cisco
sites which I've read thru, it provides me quite a good start but more on a
quick start instead of understanding it. Whereras the "developing IP
multicast network" of CiscoPress seems to be complicated to me as they are
quite lengthy. Is it important that for me to still go for this book ? or I
can supplement it from other sources ?
Appreciate your input.
Thanks in advance.
Yonger
