Configuring an Interface Role

Context

Administrators can configure an interface role based on the network location of interfaces. If an interface is connected to a user host, administrators can configure the interface role of the interface as a host interface. If the interface is connected to a router, administrators can configure the interface role of the interface as a router interface.

If the interface role of an interface is a router interface, the system forwards RA messages.
If the interface role of an interface is a host interface, the system discards RA messages.

Procedure
