routing Table

rob misz — Thu, 16 Jul 2009 16:39:16 GMT

We have 3 hp 5300 series routers directly connected to each other. 2 of the tree routers have class A networks. Switch A has 10.10.0.0 and switch C has 10.3.0.0. Switch B has a static route to each network (10.10.0.0 255.255.255.0 172.16.16.1, 10.3.0.0 255.255.255.0 172.16.16.2). My question is when I do a “show ip route” command I see the two static routes however I also see 10.0.0.0/8 with Rip as its type and its gateway as one of the switches. I checked all three switches and I really don’t know where this route is coming from. Is there anyway that this route can be removed?

Hello,

can you provide us and "show running-config" of all three switches?

Best regards,
Patrick

rip stems from the classfull ip-adress scheme.
10.0.0.0 is a class-A subnet and as such /8! rip treats it as such, it doesn't understand the /24 mask.
you'll have problems with a "segmented subnet" (two parts of the same subnet separated by another)

Looking over the Switch A I noticed that someone enabled rip on the 10.10.72.0 network while i was on vacation. Thanks for all the responses
