I'm running Dense mode between 2 routers and have the following config
on each
Ip multicast routing
Int fa0/0
Ip pim dense
Int fa1/0
Ip pim dense
(HOSTA's address is 63.240.45.33)
HOSTA--------------R1-------------------------R2-------------------HOSTB
host a is sending traffic to 223.22.22.25 and .27 but I'm not seeing it
on r2 when I do a show ip mroute.
On r1, I'm seeing the following when I do a show ip mroute:
(*, 230.22.22.27), 00:24:20/00:02:38, RP 0.0.0.0, flags: DC
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list:
FastEthernet1/0, Forward/Dense, 00:24:20/00:00:00
FastEthernet0/0, Forward/Dense, 00:24:20/00:00:00
(*, 230.22.22.25), 00:24:17/00:02:36, RP 0.0.0.0, flags: DC
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list:
FastEthernet1/0, Forward/Dense, 00:24:17/00:00:00
FastEthernet0/0, Forward/Dense, 00:24:17/00:00:00
R1 obviously knows about the two multicast destinations, shouldn't I be
seeing an entry in the mroute table if HOSTA is indeed sending to
230.22.22.25 and .27?
Also, why is the incoming interface marked as NULL?
I thought I should be seeing something more like:
(63.240.45.33,230.22.22.25) ), 00:24:20/00:02:38, RP 0.0.0.0, flags: DC
Incoming interface: FastEthernet0/0, RPF nbr 0.0.0.0
Outgoing interface list:
FastEthernet1/0, Forward/Dense, 00:24:20/00:00:00
FastEthernet0/0, Forward/Dense, 00:24:20/00:00:00
