We are running some tests on some equipment to characterize network behavior across our OC3. We were told today that the equipment to be installed at the remote end can not be placed there. The OC3 will be completed in a few days. So we need to tell management we can do this or not... Sorry for what is probably a simple question... but how do we loop the OC3 at the remote end and use it for the testing with all the equipment on one end. Is it really this simple?
IP Route 192.168.1.0/8 192.168.4.1
IP Route 192.168.2.0/8 192.168.4.1
So using the picture... We want to send from TBERD B to TBERD C but have the traffic go across the OC3 to the remote end and loop back. So... traffic from 192.168.1.2 to 192.168.2.2 via 192.168.4.1
a) the loop command should have more then one option may be loop network is the right one for your scenario
b) When you have a POS interface looped it is usually to perform OSI Layer1 tests with specialized instrument connected in place of the router on the other side.
But I see you would like to perform tests at OSI layer 3 with IP traffic generators.
In order to make this setup to work you need PBR policy based routing applied inbound on router B POS interface for destination 192.168.2.2 otherwise is traffic is looped on the POS and wil expire over it.
When T BERD B sends traffic to 192.168.2.2 the router B will receive it on a different interface and will route it to the POS using the static route.
When traffic comes back from the looped POS the PBR will send the traffic to T BERD C, but for this to work RB interface to T BERD C should not be in 192.168.2.0 network.
Well for me this setup cannot work this way.
The simplest test you can do after the loop is operational is to ping 192.168.4.2 via RB.
Also the network masks for your static routes should be /24 not /8
The network is growing and how! Data is being generated at such an exponential rate. An IDC report states that data will grow to 175 Zettabytes by 2025. With such an explosion, enterprises cannot keep sending all the incoming data directly to the cloud. T...
