Hey Raul,
In option 3 you only need the "rp-announce-filter" if you are required to do
the filtering on the mapping agent.
If you used the "send-rp-announce" with a group-list already on the RP
itself then the RP is only advertising itself for a finite set of groups and
the mapping agent filtering would be unnecessary.
Cheers,

Hi All,
My question is regarding filtering of groups for RP. We have following
options according to mode of RP advertisment,
1) ip pim rp-address 1.1.1.1 [ *access-list* ] ( On RP )
2) ip pim rp-candidate loopback0 *group-list yy* ( On RP )
**
3) ip pim send-rp-announce loopback0 *group-list yy* ( On RP )
ip pim rp-announce-filter *group-list yy* *rp-list xx * ( On Mapping
Agent )
In option 3 , rp-announce-filter is mandatory on MA ? I observerd that
without using this we can get the same result untill and unless it is
specific requirement in the task that we should filter on RP and MA as well.
Need you comments on this.
HTH,
Raul
