Hi All

I am working on Anycast config . I straight forward referred the DocCD
as i think that this is very well explained using exmple there .

R4
ip msdp peer 150.1.5.5 connect-source Loopback0
ip msdp originator-id Loopback0
!
R5
ip msdp peer 150.1.4.4 connect-source Loopback0
ip msdp originator-id Loopback0
!

On R6 as well as SW2 ; I had defined " ip pim rp-address <common
loopback of R4 amd R5> "

All the configs was fine .. But I was getting error message on R4 as
well as R5 :

*Jul 18 14:12:39.829: %PIM-6-INVALID_RP_JOIN: Received (*, 224.0.1.40)
Join from 129.1.58.8 for invalid RP 150.1.0.255
etc

Now ; when I specify the static RP on R4 as well as R5 also .. this
message disappeared and I got everything working.

Since this is not mentioned in DocCD to define the static RP on
routers where I have done the msdp configs also ; I wanted someone to
clearify that is that the only solution or am i missing something

Thnx
Gaurav Madan.
