How do I manage a SD-WAN branch router C1111-8 with a Loopback interface? I have created Loopback 100 interface under VPN 0 transport and binded it to the physical transport interface G0/0/0 but this does not work. Right now, I am managing the router through the SVI service VPN and that works but the SVI interface will not stay up without something connected to the switch port in that vlan. The template for the C1111-8 does not support "no autostate" under the vlan interface either. Does anybody have a solution for this?
