Remeber LSPs are uni-directional. TO have trafffic sent and recieved
on an LSP you need to build two.  In your case LSP "16" will be used
to send from from A to C.  LSP "17" will be used to sent traffic from C t=
o A.

LSP from A -> C
---------------

A: route add -host 192.168.3.2 gw 192.168.2.2
A: mplsadm -A -B -O gen:16:eth0:ipv4:192.168.2.2 -f 192.168.3.2/32

B: mplsadm -L eth1:0
B: mplsadm -A -B -I gen:16:0 -O gen:16:eth0:ipv4:192.168.3.2

C: mplsadm -L eth1:0
C: mplsadm -A -I gen:16:0

LSP from C -> A
---------------

C: route add -host 192.168.2.1 gw 192.168.3.1
C: mplsadm -A -B -O gen:17:eth1:ipv4:192.168.3.1 -f 192.168.2.1/32

B: mplsadm -L eth0:0
B: mplsadm -A -B -I gen:17:0 -O gen:17:eth1:ipv4:192.168.2.1

A: mplsadm -L eth0:0
A: mplsadm -A -I gen:17:0

NOTE: Ethereal and tcpdump will show "weird" packet when running ON the
LER (A or C in this setup).  This is due to where (in the Linux net stack=
)
tcpdump and ethereal snag a copy of the packet.  Right now they get a ver=
sion
of the packet that has been partially modified.

For LDP, make sure to grab ldp-portable from CVS to get the latest versio=
n.
