BIRD - Config Support for RFC 3107 - Carrying Label Information in BGP

[Thiruvazhiyan Lakshmanan]

Thanks for your reply.

When I tried to add " ip route add 192.168.1.0/24 encap mpls 100 via inet 10.10.101.1" I get "Error: either "to" is duplicate, or "encap" is a garbage."

root at ubuntu4-4-VM1:/proc/sys/net# ip route add 192.168.1.0/24 encap mpls 100 via inet 10.10.101.1
Error: either "to" is duplicate, or "encap" is a garbage.

and "ip route show" command do not show any labels to the route's output,

root at ubuntu4-4-VM1:/proc/sys/net# ip route show

Hi

You could also check if you have proper kernel and tools.

If you add the route manually:

  ip route add 192.168.1.0/24 encap mpls 100 via inet 10.10.101.1

You should check if yuo see it with label using 'ip route show'.
