Hi Guys,
I am new in the group and some quick info on the filtering process
of the candidates using a dynamic RPs. I configure r2 (loopback ip address
22.22.22.22) and r3 (loopback ip address 33.33.33.33) as poosible RP
candidates with the 'ip pim send-rp-announce loopback 0 scope 16 ' also
configured r1, r2 and r3 with as Map Agents (for the RP election purposes)
with the 'ip pim send-rp-discovery scope 16' command. The election works
fine and r3 becomes the RP because he has the higest loopback address, but
when I use the 'ip pim rp-announce-filter rp-list 1 group-list 2', trying to
filter out r3 from becoming the RP, r3 still becomes RP anyway. Was
wondering if anyone any suggestions.
