ipv6 nd reachable-time

This command sets the router advertisement time to consider a neighbor reachable after

neighbor discovery confirmation. Reachable time is specified in milliseconds. A value of zero

means the time is unspecified by the router.

Default

Format ipv6 nd reachable-time <0–3600000>

Mode

no ipv6 nd reachable-time

This command means reachable time is unspecified for the router.

Format no ipv6 nd reachable-time

Mode

ipv6 nd suppress-ra

This command suppresses router advertisement transmission on an interface.

Default

Format ipv6 nd suppress-ra

Mode

no ipv6 nd suppress-ra

This command enables router transmission on an interface.

Format no ipv6 nd suppress-ra

Mode

ipv6 nd router-preference

This is used to configure router preference value in IPv6 router advertisements on an

interface. This will indicate whether or not to prefer this router over other default routers.

Default Medium

Format ipv6 nd router-preference <high/low/medium>

Mode
