i've set up a mpls-routing net ... each edge router
is a gateway for one of the 192.168*** net ... now i wan't to
"tunnel" the mpls-net to connect to the net of the
second ler. this doesn't work without forwarding-entrys, 'cause
otherwise the arp request isn't labled and cannot be routed
correctly through the network !

e.g. i have a computer with the ip 192.168.0.1 connected on ler1
this one should connect to 192.168.1.1 on ler2. To set up the
connection the 0.1 send a packet with the arp who-has request to ler1 ...
without any forwarding entry this router sends the packet unlabled into
the network and because he doesn't have a direct connection to
1.1 he returned no arp-reply. If i entered an iptables-entry as described
earlier he labled simply each incoming packet from 0.1 and route it through
the net, so it can be recieved by 1.1 ...
