Re: [mpls-linux-devel] [mpls-linux-general] IGP with LDP support

[Maic G. <ma...@ha...>]

Hallo,

I put some trace to this posting. I marked the interesting part of the trace.

I have got an OSPF adjacency between the quagga PC and a router.
I turn on trace all on the quagga PC in the ldp section.
Than I enable ldp on the interface to the router.
The ldp adjacency comes up and both systems exchange their local label
binding. The result is, the router puts this labels as an remote binding in
its forwarding table an the quagga PC does the same.

If I use ISIS I do the same. The result was the router puts this labels as an
remote binding in its forwarding table again. But the quagga PC did this not:


2007/08/09 18:10:10 LDP: ENTER: ldp_nexthop_for_fec_session
2007/08/09 18:10:10 LDP: EXIT: ldp_nexthop_for_fec_session: NULL
2007/08/09 18:10:10 LDP: OUT: Session 10.205.0.1:0 is not a valid nexthop for
0adb0001/32


Does anybody know why this happen?


The first point in my question down is not so interesting any more.
But the third one is interesting.



Thanks.
