Create a Loop from the Router to the Network
Purpose
Creating a loop from the router to the network allows the transport-layer engineer to test the router from various points in the network. This helps the engineer isolate where the problem might be located.
Action
To create a loop from the router to the network, follow these steps:
- In configuration mode, go to the following hierarchy level:[edit]user@host# edit interfaces interface-name sonet-options
- Configure the remote loopback:[edit interfaces interface-name sonet-options]user@host# set loopback remote
- Verify the configuration:user@host# show
For example:
[edit interfaces so-1/0/0 sonet-options]user@host# show loopback remote; - Commit the change:user@host# commit
For example:
[edit interfaces so-1/0/0 sonet-options]user@host# commit commit complete
Meaning
This command loops any traffic from the network back into the network.
