Thanks guys. This means I need "ip pim rp-address" on all the routers
involved when autoRP and BSR are not used, just to be on the safe side?
thanks

R2 would not "tell" R1 that it is RP. You need to manually "tell" R1
that it
is RP with command:
ip pim rp-address 150.1.14.1
If you want to automatically exchange RP info between routers, you
should
use AutoRP or BSR.

Hi Group
I have
R1------------R2
|
|
150.1.14.1
And on R2:
Rack1R2(config)#do sh ip pim rp
Group: 239.1.1.1, RP: 150.1.14.1, uptime 00:02:28, expires never
Group: 224.0.1.40, RP: 150.1.14.1, uptime 00:06:28, expires never
Rack1R2(config)#do sh run | in pim
ip pim sparse-mode
ip pim sparse-mode
ip pim rp-address 150.1.14.1
Rack1R2(config)#do ping 150.1.14.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 150.1.14.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/60/104 ms
Rack1R2(config)#
And on R1:
Rack1R1(config)#do sh run int e0/1
Building configuration...
Current configuration : 149 bytes
!
interface Ethernet0/1
ip address 150.1.14.1 255.255.255.0
ip pim sparse-mode
ip igmp join-group 239.1.1.1
no ip mroute-cache
half-duplex
end
Rack1R1(config)#do sh ip pim rp
Group: 239.1.1.1, RP: 0.0.0.0
Rack1R1(config)#
My understanding is that if R2 tells R1 that R1 is the RP, R1 should
automatically behave like a RP. I don't understand why my R1 is not
considering itself as the RP?
Thanks a lot....
