hi,
i have some doubts about when we implement L2 VPN over MPLS we SHOULD keep loop
free. See draft-lasserre-tls-mpls-00.txt. why?
why not just use such a simple algorithm described below?
1. if the L2 frames are received from a interface connecting to a CE, forward the
frames to all other local interfaces in the same VPN, and also to all other remote PEs
which sites within the same VPN are connecting to.
2. if the L2 frames are received from other PE, just forward the frames to all
local interfaces in the same VPN with the frame.
is it like the full mesh topology for the IBGP peers?
and what will happen, if protocol operations in this way?
thanks.
