I will do a debug and let you know the results, for the PIM SSM related
issues.
With respect to the PIM register issue, i had this topology
if1------x1,x2---------if2
I mentioned if2 as the RP on XORP router(x1 and x2 represent the XORP
interfaces and if1 and if2 are interfaces on my machine), the register_vif
takes IP address of interface x1.
I am sending a UDP data packet from if1 to 225.1.1.1, and I am capturing
packets on if2 using ethereal, but no PIM Register packets are arriving on
if2.
I am receiving PIM hello on both if1 and if2.
Also, I dont need to send PIM hello from if1 and if2 as it is not required
since PIM Registers are unicast.
Am i missing something.
Regards,
Neeraj.
