Reachibility Issue.

Hello Seniors,

I had a query if in case you are not able to ping any of your routers or
Backbone interfaces what is the best possible troubleshooting steps.

As per my understanding I would follow the following steps.

1) sh ip int b -- check the line protocol
2) check duplex settings
3) trace route check .
4) check for any access-list configured that would block ping reachibility.
5) check proper access vlan passed in the given interface
6) ?
7) ?
8) ?
9) ?

Also if possible let me know what would be the best approach to
troubleshoot any layer 2 & Layer 3 related problems if possible.

Please let me know what would be the best approach, kindly reply to my query
as per your convenience

Have a pleasant day!!!

Regards

Sajid .
