in a small deployment where border nodes are not required

in a design where fabric edge nodes are unable to provide control plane functionality

in designs without Cisco DNA Center

when there is a requirement for frequent roaming of endpoints across fabric edge nodes

Use BGP AS-path prepending to influence egress traffic and use MED to influence ingress traffic from the branch.

HSRP priorities must match the OMP routing policy to prefer one WAN Edge over the other.

Traffic must be symmetrical as it egresses the WAN Edges and returns from remote sites for DPI to function properly.

Configure BFD between WAN Edge routers to detect sub-second link failures.
