Re: [mpls-linux-general] How do I map traffic to an LSP?

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

The LDP part of quagga-mpls is not ready for users, it is still in
development.  You can use the static LSP configuration though.
See the examples on http://mpls-linux.sf.net for more info.

You can use iptables to map traffic to a LSP.  You can also use iproute2
to map traffic to a LSP.  For iptables you can use all of the normal
iptables commands (google for a iptables howto) with the addition
of the spec_nh target (-j spec_nh --spec_nh 0x8847:0x2).  Here is a simple
iptables examples (you will want to google for a iptables howto to
learn more about iptables syntax):

    iptables -A OUTPUT -d 1.1.1.1/32 -j spec_nh --spec_nh 0x8847:0x2

0x2 is the key of a NHLFE
