Suggestions for Tagging a management vlan over an ISIS/SPBM link.

Hello!

I have a scenario that involves two UISP antennas that will be linking together a 5420 to a 5320.

I'm able to establish adjacencies with no issues, but unfortunately the unifi p2p's do not include a separate physical management interface.

Is there a way to tag a management vlan over an ISIS/SPBM interface?

Hi,

I imagine that using Fabric Extend you could achieve what you are looking for

I've setup a logical interface on the two switches. However, when attempting to tag the management vlan for the UISP antennas, I get this.

There is a successful adjacency with the logical interfaces going over the UISP antennas. The Logical interfaces currently are using vlan 10 and 20 (following the illustration you posted).

did I set something up wrong?

Could you please clarify the following for us?
Would you like to establish a Fabric Connect connection between a 5420 and a 5320 via UISP antennas? Would you also like to use the uplink from the switches to these antennas as an uplink for the management interface of the UISP antennas?
