Re: [mpls-linux-general] Problem with ip route + lsp

[James R. L. <jl...@mi...>]

Where did you read this example?  The exmaple your using specifies the
old syntax.  The new syntax is:

ip route add 1.1.1.1/32 via 2.2.2.2 spec_nh 0x8847 0x2

where 0x8847 tells the special next hop system you want to use MPLS
and the 0x2 tells it to used NHLFE with index 0x2
