First of all, hello to everybody in the community :-)!
Now the problem. I have two switches on two different locations. switches are 3750 and 3560, connected with two links- P2P fiber link (C1), and also some kind of P2P link (C2), but data is passing through ISP cloud.
The switches are in two separate VTP domains, both have their VLANs, we only need connection from one side to other, and route to specific networks, we configured static routes for that. Also for that purpose is crated on one side VLAN55 and on the other side VLAN5. With one link C1 everything is working fine, but when we connect other link C2, we have network loss and no connection to the other side.
So to the question.. what is the best way to configure this links to be redundant?? I understand that there is two approach, on the L2 (STP) or on the L3 (OSPF,EIGRP).
Also any advice on troubleshooting would bi nice.
Thanks in advance and kind regards,
