Hello Paul,
The advanced edge license allows you to configure OSPF-edge features. Here are the caveats from our user guide:
OSPF Edge Mode is a subset of OSPF available on platforms with an Advanced Edge license.There are two restrictions on OSPF Edge Mode:
• At most, four Active OSPF VLAN interfaces are permitted. There is no restriction on the number of
Passive interfaces.
• The OSPF Priority on VLANs is 0, and is not configurable. This prevents the system from acting as a
DR or BDR.
