Usage Guidelines

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

Example

# On GE0/0/1, configure the interface role as a router interface for IPv6 RA guard.
