I have a p4200 with version 8.0 software and two ethernet
connection. The configuration info in question is ....
-------------------------------------
IP config>list prot
ARP Subnet routing: disabled
RIP: enabled
Originate default off
Per-interface address flags:
intf 0 128.116.64.1 Send net routes
intf 1 128.117.64.1 Send no routes
Received RIP packets are ignored.
EGP: disabled
Routing information interchange: off
Advertised EGP metric: 0
-------------------------------------
All I want is to advertise with RIP on one side the nets connected
on the other side. That is, send a RIP packet out to 128.116
with network 128.117 at 1 hop.
Instead, with this RIP configuration I get 3 packets full of routes
being sent that include a hop count of 16 for all routes except
for 128.117 which has hop count of 1.
This has the effect that I want, but is a rather poor way of doing it
I would say. All known routes seem to be put in all RIP packets!
Is there a way to get rid of this unneccessary burden in the RIP
broadcasts?

You're seeing the effect of split horizon with poisoned return. This behavior actually helps to prevent routing loops in most configurations, though it may overkill for your particular situation... Thanks, Milo

>Is there a way to get rid of this unneccessary burden in the RIP >broadcasts? I think this will work: Configure the p4200 to only send information about directly attached networks out the 128.116 interface. The commands to do so are: enable send direct disable send net Jeff

However, "static" really means directly connected networks in addition to statically configured networks. Proteon treats them as the same and calls them "static". Trivial point, but I stumbled over it in the beginning. I think this will do what you want, unless you have some statically configured nets in there. Good advice. Kent England, Boston U
