OSPFv3 (Open Shortest Path First version 3) Edge Mode is a subset of OSPFv3 available on platforms with an Advanced Edge license.
At most, four Active OSPFv3 VLAN (Virtual LAN) interfaces are permitted. There is no restriction on the number of Passive interfaces.
The OSPFv3 Priority on VLANs is 0, and is not configurable. This prevents the system from acting as a DR or BDR.
