Networking:multicast source--NE40--S6506--Switchmulticast user
select PIM
SM to do multicast protocol. Select the interface connecting NE40 and S6506to do bsr and rp
the relative configuration on NE40:

[NE40] pim
[NE40-pim] c-bsr ethernet 3/0/0 30 2
[NE40-pim] c-rp ethernet 3/0/0 
after doing the relative configuration,detect the multicast route cannot be established.

Handling Process

1.display pim bsr-info and not see the information of bsr,but bsr has already configured.
2.check carefully and detect the slot 3 line card of NE40 is the layer 2 board,which means ethernet3/0/0 is layer 2 interface.
3.For the interface acting as bsr and rp, at least it is layer 3 interface,this is the key of the problem,change the interface of c-bsr and c-rp to the vlanif10 where ethernet3/0/0 locates,the problem is solved. The configuration is:
[NE40] pim
[NE40-pim] c-bsr vlanif 10 30 2
[NE40-pim] c-rp vlanif  10

Root Cause

For the interface acting as bsr and rp,at least it is layer 3 interface.
while NE40 supports layer 2 board and layer 3,so as configuring c-bsr and c-rp
on NE40,we can configure ethernetParameter after the Command of c-bsr.
for S8016,
S6506 etc layer 3 LSW,on Command,we cannot configure ethernet directly,only vlanif.
so as testing PIM-SM
,select layer 3 interface as configuring c-bsr and c-rp.
