NTP TroubleShooting

NTP provide time synchronization in the network devices. NTP TS its just like verifying each configuration steps except with minor exceptions. Lets take those exceptions along with common causes in NTP TS. I deliberately introduce multiple issues in this topology. These issues may not necessarily be from NTP.

You just need to copy and paste the initial configuration on all the devices of any INE Rack and start working on the TS ticket.

Note: You just need to take care of rack number. Here I have used Rack 1 .
Note: TRY NOT TO USE "Show run" commands for better learning purposes

Topology Diagram:

Ticket1: NTP clients are not synchronized with NTP server. Fix it.

EIGRP TroubleShooting

EIGRP TS ticket may sometimes create unexpected problems. Lets take an EIGRP Troubleshooting ticket. I deliberately introduce multiple issues in this topology. These issues may not necessarily be from EIGRP.

You just need to copy and paste the initial configuration on concern devices of any INE Rack and start working on the TS ticket.

Note: You just need to take care of rack number. Here I have used Rack 1 .

Note: TRY NOT TO USE "Show run" commands for better learning purposes

Topology Diagram:

Ticket1: Loopback0 interfaces of SW1 and R4 are unable to reach each other. Fix it

I will post the solution of this ticket once i get responses from you guys. Thanks.

OSPF TroubleShooting

OSPF TS is not that difficult it self but sometimes other underlying layer 2 technologies make the TS difficult. Lets take an OSPF Troubleshooting ticket. I deliberately introduce multiple issues in this topology. These issues may not necessarily be from OSPF.

You just need to copy and paste the initial configuration on concern devices of any INE Rack and start working on the TS ticket.

Note: You just need to take care of rack number. Here I have used Rack 1 .

Note: TRY NOT TO USE "Show run" commands for better learning purposes

Topology Diagram:

Ticket1: R1 and R2 are not forming ospf adjacency. Fix it. There can be multiple issue with this TS ticket.

MPLS TroubleShooting

MPLS TS is something many of us fear with. Lets take a troubleshooting ticket on MPLS to understand this technology in depth. I deliberately introduce multiple issues in this topology. These issues may not necessarily be from MPLS.

You just need to copy and paste the initial configuration on all the devices of any INE Rack and start working on the TS ticket.

Note: You just need to take care of rack number. Here I have used Rack 1 .
Note: TRY NOT TO USE "Show run" commands for better learning purposes

Topology Diagram:

Ticket:Vlan 7 is unable to reach Vlan 8. Fix it. There can be multiple issues in this TS ticket.
