Route added automaticly ??

Hello,

I have a strange issue regarding a ip route for a single host on my netapp.

A route for a single host is added automaticliy with " Link# " as gateway. But it's not a good route. This host is not in the same subnet as the netapp.

Normaly, to join this host, the default gateway should work. Instead of this, this strange route appear automaticly.

If I delete it and then ping the remote host, this route appear another time. If I delete it and then add manually a good route to send packet to the default gateway, it's work.

Someone now why this route come automaticly

The router separate the both subnet is a server free BSD based with two NICs

Thanks

Does it still happen if you try to disable option ip.fastpath?

Is the system on any networks that utilize RIPv* and is routed on? Per the manpage for routed:

"Routed is a daemon invoked at boot time to manage the network routing tables. It uses Routing Information Protocol, RIPv1 (RFC 1058), RIPv2 (RFC 1723), and Internet Router Discovery Protocol (RFC 1256) to maintain the kernel routing table. The RIPv1 protocol is based on the reference BSD 4.3 daemon.

It listens on the udp socket for the route service for Routing Information Protocol packets. It also solicits multicast Router Discovery ICMP messages.

When started (or when a network interface is later turned on), routed uses an AF_ROUTE address family facility to find those directly connected interfaces configured into the system and marked "up". It adds necessary routes for the interfaces to the kernel routing table. Soon after being first started, and provided there is at least one interface on which RIP has not been disabled, routed deletes all pre-existing non-static routes in kernel table. Static routes in the kernel table are preserved."

Could be a long shot but worth looking into real quick...
