HI Everyone,

I have a problem about multicast on N5672.The unicast routing operating by OSPF,there are two ports connect to other two N5672 in this device,one port is E1/10,the other port is E1/11,we only issue "ip pim sparse-mode" on E1/10,but we can see E1/11 in incoming interface.Just as this:

---------------------------------------------

N5672UP (config)# sh ip mroute

(192.168.6.4/32, 239.2.1.1/32), uptime: 00:33:04, static ip pim mrib
  Incoming interface: Ethernet1/11, RPF nbr: 172.16.1.100  <<<<<E1/11 not config "ip pim sparse-mode"
  Outgoing interface list: (count: 1)
    Ethernet1/20, uptime: 00:33:04, static, pim

---------------------------------------------

system:    version 7.1(5)N1(1)

---------------------------------------------

So,i feel it's abnomal.Do you have the same issue?Is there any explain?

BR&Thanks
