Hi All,

Kindly clarify expected behavior of PIM-BIDIR DF election. 

I have two RP with same group address  but different group  mask length. like below.

ip pim rp-address 6.6.6.6 group-list 226.0.0.0 /8 bidir
ip pim rp-address 5.5.5.5 group-list 226.0.0.0 /16 bidir

My understand is, During DF election only one RP will be elected not both 6.6.6.6 and 5.5.5.5.

Cisco # show ip pim interface df

Interface           RP Address      DF Winner       Metric    Uptime
Vlan 5              6.6.6.6         5.5.5.48        0         00:00:09
Vlan 9              6.6.6.6         9.9.9.14        0         00:00:09
Vlan 10            6.6.6.6         10.10.10.14     0         00:00:09

 

thanks in advance. please share some information. any information is really helpful for me.

 

thanks
