This makes sense. Its just that I have been advised to route all 3000 subnets to a procurve 4200, and put any necessary routes to specific devices all in the 4200.   As long as its not going to hurt anything, I can re-arrange things as and when....
I just got a whole bunch of these msgs that I had never seen before..

thanks,
jp



This is typical when the gateway passes the packet onto another router on the same network interface. This is called ICMP redirects. When this condition happens the first router sends an ICMP redirect to the host (HP3000) telling it to update it's routing tables and passes it the ip address of the router to which "it" routes the packets to.

So your route for 192.168.53.0 really looks as though it being told to go to the router on .1 by the router on .250.

With some routers you can tell them to disabled the ICMP redirects.

Subject: [HP3000-L] gateway redirects severe

I have looked this up on the web, and what I found doesn't help much.
Doesn't seem to be causing a problem, but...

We have moved some subnets from one data link to another. We have also implemented routings in a Procurve 4200 to simplify things.

Hence the moved subnets have been pointed at the 4200, which then does the routing.

When I look at the routings I see stuff like below - is the difference between the subnet and a specific addr the issue?
