Hallo community,

I have a problem in eNSP and also if I try it with EVE-NG its the same. When I have a non-router on a stick configuration and there are to L3 Ports that dot1q terminate the tags, on Aruba termination happens alone and on Cisco you can lease on every Subinterface the IP of a Loopback or physical interface. But on AR1220 with 4GEW-T model and also without, I am not able to use the unnumbered command to use a ip from on an other physical port or subinterface. As example you would on IOS configure the subinterface and borrow the ip for every subinterface that dot1q handle the same Vlan Tags.

What would be the approach on VRP for the configuration, if you do not have a simpe Router on a stick topology and there are multiple interfaces that need to encapsulate the same vlans on multiple L3 interface.
