routing problem

[Stefan Harrington-Palme]

Hi guys and girls(maybe)....

I have a question.

We have a pile of switches around out side with two 5304's in the middle (192.168.99.1 and 99.2).

We also have a BT MPLS box(192.168.99.218) joining our country offices together.

From the CORE switches I am able to ping the MPLS box.

From the non-core switches I am unable to ping the MPLS box or (obviously) anything beyond it, in this case 192.168.10.11.

We have the default VLAN (1) and a management VLAN (99)

I AM able to ping 192.168.10.11 from the core switches.

We use 4 different subnets for users. 192.168.1.x, 2.x, 4.x, 5.x - Only people who are on the 192.168.1.x subnet and using 192.168.1.67 as their default gateway are able to use the MPLS to talk to our other offices.

If someone is on 192.168.2.x etc there is no response for the MPLS. They CAN however talk to any other subnet internally.


If anyone could point me in the right direction that'd be great or if I can clarify anything please let me know.

Stefan

I havn't read the config's in detail but...
does the MPLS box function as a router ?
or is it transparent at Layer-2?

if it does routing and the other subnets are added later to an initial setup, then you may need your provider of the mpls-network to add routes for the new subnets.

That's a damn good point. I believe it routes. I'll look into that now.

[Stefan Harrington-Palme]

That was it, I have spoken to BT and there was only a .1 route set up. Thanks! :)

[Pieter 't Hart]

glad to be able to give the right pointer.
thanks for the points.

Routing for our additional subnets had not been set up. Problem had nothing to do with the switches.
