=======> coz the destination network is there..... its still a viable config isnt it..incase of assymetric uplinks and downlinks? ......wht stops u from "not having a route to the source" as routing is destination IP based... some particular network may be covered with 0.0.0.0/0 for example and you may have no routing entry for it... or you could be having a customer who uplinks a particular network segment via your ISP, but doesnt advertise his network to you as he actually downlinks that network from somewhere else...nothing to stop that topology either.........right?
And if the destination network isn't there, you send the ICMP Net Unreachable to where? -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech
