Direct connected links are not labeled. LDPd does a local binding (for 10.0.0.0/24 in yout case), but this isn't distributed. From=20PE1 there should only be a label to the 13.0.0.0/xx net. Would be unnecessary for direct neighbours to send labeled packets... Strange that you are able to send packets to those dummy interfaces. They neither show up via ifconfig nor via ip route show. The routes are not distributed on my systems. You did not use dummy interfaces before, did you? All I know is that they have to be there ;-) Regards, Marco > Hi: > For you, Marco this is the config I made for the following simple scenari= o: > eth0 eth1 eth1 eth0 > 12.0.0.1-------PE1---------------------PE2-------13.0.0.1 > .1 10.0.0.0/24 .2 > I keep the config files for zebra, ospfd and ldpd empty (only log > file and hostname) and I configure everything via vtysh: > PE1 > -------------------------------------------------------------------------- > router ospf > network 10.0.0.0/24 area 0 > network 12.0.0.0/24 area 0 > mpls ldp > int eth1 > mpls labelspace 0 > mpls ip > PE2 > -------------------------------------------------------------------------- > router ospf > network 10.0.0.0/24 area 0 > network 13.0.0.0/24 area 0 > mpls ldp > int eth1 > mpls labelspace 0 > mpls ip=20 > At first I only type in the ospf commands and wait until new routes > are learned to configure LDP.
