We are planning to migrate our DWAN system to SDWAN.
Currently we are using hardware C1111-8P which supports SDWAN and two MPLS circuit and use L2 port as the LAN port.
This device only has two L3 ports(and all connect to WAN), if I move to SDWAN can I still use the L2 port as a LAN port and use the vlan to establish OSPF with Core switch?
