Is there a BSR equivalent to “ip pim rp-announce-filter”?
Hobbs,
This is a different concept than with AutoRP. With BSR, the BSR does not decide which is the best RP for each group (as the MA in AutoRP does), he just sends out all group to rp-mapping information via bootstrap messages to the other routers (224.0.0.13). Then, the other PIM routers choose the best RP for each group. So you have to filter in the rp candidate messages for which group the related rp is responsible ip pim rp-candidate interface-type interface-number [group-list access-list] [interval seconds] [priority value]
With AutoRP, the Mapping Agent decides, after he got all the rp-announce, which rp is responsible for which group (based on the higher ip address if two rp announce the same group). So if we have multiple Auto-RP domains crossing, or different mapping agents, we may want to specify for which RP’s the Mapping agent is in charge of. We can do that with a rp-announce filter.
I hope my explanation is not too confusing

Hello,
Is there a BSR equivalent to “ip pim rp-announce-filter” ? If you had to restrict which groups a router was RP for, at the BSR - how could you do it?
thanks,
