It looks like you've got a working MPLS kernel. Try building a LSP
via the quagga interface, in vtysh try:
monkey1(config)# mpls static 0
monkey1(config-ls)# label-map gen 160 swap gen 170 nexthop eth2 192.168.4.2
monkey1(config-ls)# end
monkey1# show mpls forwarding
Insegments:
Lbl Spc Label Owner
0 160 static (inactive)
Total 1
Outsegments:
Interface Label Next Hop Owner
eth2 170 192.168.4.2 static (inactive)
Total 1
Cross Connects:
Lbl Spc In Label Out Label Interface Next Hop Owner
0 160 170 eth2 192.168.4.2 static (inac=
tive)Total 1
monkey1#
Make sure you're seeing the MPLS debug in 'dmesg'
BTW your should update your quagga-mpls and ldp-portable tree, I have submi=
tted
lots of changes since you built your RPM.
