RE: MA on spoke router !! Rp on another spoke !! sender/receier

I believe that tunneling would have to be used in a situation like this.

The Auto-RP mapping agent on a spoke device in a Frame hub and spoke environment has issues, and as such, the R&S Lab Exam would not have us configure this, unless they permitted some very big "workarounds".

Subject: MA on spoke router !! Rp on another spoke !! sender/receier on another spoke ...

 hi experts ,

if in a lab environment the task ask to configure MA on a spoke router which dont have direct l2 circuits with others except the Hub , the other spokes will not get mappings due to lack of l2 connectivity . what are different work around we can have ???

i m getting a lot of frustration after trying hard to get a successful ping from a spoke routers.

R1 is a hub R2 , R3 , R4 are spokes . R2 is RP and R3 is MA , the
receivers are behind R4 . All running pim sparse mode , no rpf issues as
topology is very simple running single igp and pim on all interface (each
router has only one s0/0 int connected to cloud )

however R4 is not getting MA messages and ping fails . i have given ip pim nbma mode / auto rp listener command on the hub router as well.

has any one tried multi casting heavily on dynamips and spotted any issues ?
