Re: multicast works even if interface is out of route table

Hi Brian,

but from R3 or R2 I 'm not able to reach 1.1.1.1 (R1's l 0 )
you mean that that router can join a group from every interface despite
that interface is not on routing table?
You mean that the join gets to the RP using the reachable interface instead?
Actually this makes a bit more sense to me now..
