directly connected links

If I have 2 routers both connected via serial, if 1 router is on a different network, will this appear as a directly connected network, or would that particular network need a route pointing to it ?

Re: directly connected links

hi carl

if one serial interface IP is on another subnet.then also you can see interface & Protocol status as UP UP .

regarding the routing i didnt get u, can you just explain the last sentence?

Re: directly connected links

Hi

In routers,particularly cisco routers, u will not be able to use same networks across serial interfaces(until and unless u are bridging).In ur case,u will notice that while doing ip routing, u will not able to ping the next router,if they are in same network.

Below is the example of 3 router's connectivity:------

Router1---router2---router3

Router1:----

e0:192.168.1.1/255.255.255.0

s0:10.0.0.1/255.255.255.252

Router2:

e0:192.168.2.1/255.255.255.0

s0:10.0.0.2/255.255.255.252

s1:10.0.0.5/255.255.255.252

Router3:

e0:192.168.3.1/255.255.255.0

s0:10.0.0.6/255.255.255.252

Start RIP on all 3 of them.

U will be able to communicate withh all the 3 networks

Hope this solves ur prob.

Regards

JD
