[mpls-linux-general] LDP with Cisco router

[Mattias P. <mat...@op...>]

I=92m trying to set up a pc running zebra/ldp to establish a LDP session =
with
a Cisco router. I haven=92t had any luck in completing this. So far, =
they are
exchanging Hello messages and the Cisco router is trying to establish a =
TCP
connection (LDP session, port 646) with the pc. But this is where =
nothing
more happens; mplsd is not responding to the TCP SYN packets.

I=92ve noticed a few things but have little knowledge of what it means: =
The
Hello messages from mplsd have the CSN TLV and not the Transport Address =
TLV
while the Hello messages from the Cisco router do not have the CSN TLV =
and
has the Transport Address TLV.

When executing "show ldp neighbour" on mplsd the following is returned:

Peer LDP Ident: 192.168.200.6:0; Local LDP Ident: 10.2.1.98:0
        TCP connection: n/a
        State: discovery; Msgs sent/recv: -/-;
        Up time: -
        LDP discovery sources:
          eth1


Can any one tell me why no LDP session is established? If nobody knows,
perhaps someone could direct me to what I should look for in the
configurations?

Thanks!!
