Connection issue

Unanswered Question
Sep 8th, 2008

Hi..I seem to be having a strange issue. I have routers A and B. B is connected to the network through A. I can ping router B through A but not from outside. When I do a tracert also the trace gets stuck at Router A's serial interface (the interface connected to the outside network). Router B is connected through the Ethernet interface of the Router.

I have checked and added default routes but its not working. There are also no access-lists in question on both of these routers. Does anyone have any suggestions?

I have this problem too.

Hello Uzma,

it looks like that the rest of internetwork is not aware of RB's subnets.

On Ra you may need to redistribute static routes in the routing protocol you are using

Hope to help

I'm not using any Routing protocol. All I have is static routes everywhere..

Hello Uzma,

in this case you need to add everywhere specific static routes for the RB's subnets pointing to the correct outgoing interface/IP next hop up to reach RA.

Using multiple default routes does not provide the desired result.

Hope to help

I am aware of that. I have added static routes for each subnet I need it to connect with. Their is only one default route on each router.
