If you use the newest kernel and iptables I've posted (1.938)
you can use iptables to sent specific traffic down a LSP.

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

Where 0x8847 tells the spec_nh system your setting a MPLS nexthop
and 0x2 is the key of the NHLFE created via mplsadm2.

(you can use other iptables 'filters', see you an iptables howto
for more info on selecting traffic)  The key to this working is the
-A OUTPUT and the -j spec_nh --spec_nh 0x8847:0x2, in between there you
can use whatever iptables 'filters' you want.
