You can't do that. If you know the mac of the other router, do domething
like:
#ip ro add 172.20.20.20/32 dev eth1 scope link
#arp -s 172.20.20.20 <mac>
#ip ro add 192.168.1.0/24 via 172.20.20.20.20
So .. this just show why you can't just route throught an ethernet
device, unless you "want" to do some multicast flood.
