Strange Problem

Hi ppl

i am facing a strange problem please see the pic attached

i have a 3620 and a 2501 at location A

router a loc B(2501) is connected to rouetr a Loc A (2501). placing two routers at a location makes no sense so i thought to pick 2501 placed at location A. to do this i just configured a serial port s0/5 may be on the same network as is router 2501 at loc B

its strange that only 2501 at loc A communicates with that at Loc B

3620 at loc A cannot communicate with 2501 at Loc B

can somebody gimme advice to get out of this?

Regards

Re: Strange Problem

The reason the 2501 in location A can communicate with the 2501 in location B is that they are directly connected. You need to have either a routing protocol or static routes configured in order to provide full connectivity between all routers?

Hope this helps,

Re: Strange Problem

i think i could not clarify my question

2501 is connected to 2501

when i connect 2510 of locb to 3620 of loc A through serial port(E1) and bring both the ports on same netwrok i.e 192.1.26.0/24 they should be able to ping each other

rotuing is next step when i nedd to access these machine from any third machine

they both dont speak to each other even when physically connected
