The above configure will only label switch packets at the LSR, you do not have
anything configure to add labels or remove labels from the packets at the
ingress and egress:

Ingress:

-terminate LSP 16
mplsadm -v -L eth1:0
mplsadm -A -I gen:16:0

-orginate LSP 16
route add -net 192.168.200.0/24 gw 192.168.100.1
mplsadm -A -B -O gen:16:eth1:ipv4:192.168.100.1 -f 192.168.200.0/24

Egress:

-terminate LSP 16
mplsadm -v -L eth1:0
mplsadm -A -I gen:16:0

-orginate LSP 16
route add -net 192.168.100.0/24 gw 192.168.200.1
mplsadm -A -B -O gen:16:eth1:ipv4:192.168.200.1 -f 192.168.100.0/24
