Internet routing / multiple Internet circuits

Let's say I have one router with 10 T1 circuits and each T1 has an IP block of:

200.200.1.1/24

200.200.2.1/24

200.200.3.1/24

200.200.4.1/24

...

...

200.200.10.1/24

Is there a way to setup the routing so the traffic that enter the router on a particular T1 also exits that same T1?

The problem I have now is that no matter which T1 the traffic enters, the default route is sending the repsonses out a differnt interface.

Basically, I need to be able to ping each one of those T1's from any Internet computer.

Kinda like a reverse PBR map except that I don't know the source networks.

There is no BGP running on these either.

Thanks!!

Re: Internet routing / multiple Internet circuits

Hi

If you are trying for a setup for monitoring purpose(monitoring the T1 links) i would suggest to have a loopback ips routed via respective T1 so that when u ping that loopback ip you wont get the response if the respective T1 through its routed goes down.

You can also try to do a tracert and find out the path it takes to reach the destination ip or else you can ping the T1 address configured at the ISP end.
