Hi Folks,
There is issue with pim NBMA mode.
R5 is the hub Router and sending traffic to group 232.2.2.2, The problem
here is that despite of putting ip pim NBMA command on R5 Serial
interface, i am getting three replies; means R5 is still sending traffic
to all DLCIs configured under R5 serial interface.
R5#ping 232.2.2.2
Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 232.2.2.2, timeout is 2 seconds:
