I'm currently in the process of extending 3 seperate networks to another building. (Bldg 100 to Bldg 200)
There is a network in place between the two buildings and the people that own the network are giving us a VLAN to ride over. They have assigned us the VLAN 1050.
My question is, if I have 3 separate switched networks and they were all built using Native VLAN 1, and I want to have the three network connect to a single switch, get transported over the local provided VLAN 1050, then separated back out at Bldg 200, how should I setup the switches.
So in reference to the drawing below, I want Switch A1 to be able to talk to Switch A2 over the provided VLAN 1050, the same as Switch B1 to B2 and C1 to C2, but all the network must remain logically seperated.
So far I have connected Switch D1 to the local provided switch and made the uplink port a trunk port and set the Native Trunk VLAN to 1050.
I did the same on Switch D2 and I can see the switches when I do a sh cdp nei.
BTW A1, B1, C1, D1, A2, B2, C2, and D2 are all Cisco switches.
The switches that are providing transport over VLAN 1050 are Foundry switches that I do not have access to their configuration.
