route syntax

there are two computers, arrakis and caladan.  I'm trying to ping from
arrakis eth1, which is a D-Link NIC, to caladan, ignoring arrakis
eth0.

I believe that the problem is in the last line of route, so would like
to remove that line.  I might remove all mention of eth0, too.

I'm looking into the man page, but the syntax escapes me at the moment :(
