Can't Connect to Systems in other Office Locations

[Meri Christmas]

Good Afternoon

My company has set up a new office, I will call "Central". We configured a 3850 switch connected to a ASA 4406 firewall. Every is working fine except for one problem.

I can't connect to printers, servers, or computers in our other offices, I will call "East" and "West".

I cannot ping to devices in the east and west offices including the switches located in those offices

I cannot map to a server that's located in our east office

If I go to the east office for example, I can see and connect to printers and such in the west office. Likewise if I go to the west office I can connect to anything in the east office.

But the central office...nothing.

I can supply any document you request to help me figure this out. I've been over my config files for my switches but outside of adding a ACL on the new central switch, I can't figure out what's going on.

Thanks in advance.

Hi, 

How to both offices are connected? Are you using VLAN connection/Direct L2 link/MPLS?

Can you share ACL configuration along with network diagram?

MPLS - 

But I found the problem.

I added a route to the switch in the east office yesterday. I saved it but when I went to the east office today, I noticed that the route did not save. I put it in again but it wouldn't save. I decided to place the route on the switch in the west office and it worked! Now the central office can connect to the west office location and visa versa.

I knew the only thing that was keeping the offices from seeing each other was a route. When I added the route to the switch at the east office and it still didn't work, I became perplexed and open this thread. 

But now since I am unable to save the route on the switch in the east office, I realize the problem is the switch. It just won't save. I've even tried to add a test route but that couldn't save that either.

Then I did a "no ip route" command for the route I thought was saved but I received no route found from the switch.

So I think my problem is actually the 2960x switch at the east office.

OK now my "saving routes" issue is resolved. The switch only holds 16 routes. I removed the routes that we no longer use (from locations that don't exists anymore) and added the new ones. DONE! 

Thanks much. 

I'm a newbie so I will probably have some more issues that perplex me.
