BackHaul Connectivity Problem

Tongesai
Level 1
Level 1

I have a bit of a problem with my setup.

Refer to the configs below.

The routers a connected on a backhaul for my VSAT Network and router 2's ethernet connects into the DPC(Data Port Card) at the VSAT HUB/EarthSatation on Ip Address

190.0.1.187/24 and its ethernet0 is 190.0.1.186/24

When I am sitting in the router 1 at Head Office, I can successfully ping all the sites on my network (all entries in /etc/routes file)

but when sit in the Server (ip 190.0.0.199/24) I can only ping as far as the ethernet of router2 (190.0.1.186/24)at Earth Station/HUB. I cant even ping the DPC (190.0.1.187/24) in the same subnet!!

I feel the problem is with the Server but I cant figure out where!

Check the configuration of the DPC. Make sure that it has a default gateway of 190.0.1.186, or a route that points the server's network to that address.

Good luck.

Thanks for your advice but it didnt work, it had to work in some other way!!

I had to restart the server (Digital Unix) with the new routing table and it worked!!

Are the E0's of R1 & R2 supposed to be on the network 190.0.0.0/24 ?

If they are the e0 of router 2 has an ip address on a different subnet 190.0.1.0/24

Thanks,

I had to restart the server for the new routing table to take effect and it worked.
