To configure an mroute, use this command; ip mroute <ip addr netmask> <
next-hop rpf ip-addr | next-hop interface> where the 1st ip addr is the ip
addr of the mcast source i.e. a regular ip addr - not an mcast addr.

Hi Lee,
let's say the layout looks like that:
Src
|
R1----------------R2
| |
| |
R3---------------R4
| (RP) |
|___________R5(mapping)
the RPF faillure happens on R4 (it sees R5 as the rpf nbr instead of R2)
My mroute looks like: ip mroute src-IP mask R2'sIPaddress
Any idea?
Cheers,
JP

RE: RPF failure
It's sounds like your ip mroute statement is wrong, what's your config?
This static route will override any other dynamically learnt routes.

Hi All,
I'm currently working on a multicast routing scenario on which I'd
appreciate your comments.
One of my routers is dropping the multicast feed because of a multicast
faillure : Its rpf nbr is the mapping agent (I'm using auto-rp) instead of
being the correct rpf (to the source).
I tried to add a multicast static route (even played with the admin
distances, ...) but I doesn't seem to change anything: the static route is
added to the config but when I type sh ip mroute <group> , the rpf nbr is
still the mapping agent.
I really don't get it... Does anyone have an idea?
Thank you
JP
