ipv6 nd reachable-time
e
Configure the amount of time that a remote IPv6 node is considered available after a
reachability confirmation event has occurred. The description of reachable time from
RFC 2461 (http://tools.ietf.org/html/rfc2461) is:
Reachable Time: 32-bit unsigned integer. The time, in milliseconds, that a node
assumes a neighbor is reachable after having received a reachability confirmation.
Used by the Neighbor Unreachability Detection algorithm. A value of zero means
unspecified (by this router).
Syntax
ipv6 nd reachable-time {milliseconds}
To restore the default time, use the
no ipv6 nd reachable-time command.
Parameters
Defaults
3600000 milliseconds
Command Modes
INTERFACE
ipv6 nd suppress-ra
e
Suppress the IPv6 router advertisement transmissions on an interface.
Syntax
ipv6 nd suppress-ra
To enable the sending of IPv6 router advertisement transmissions on an interface, use
the
no ipv6 nd suppress-ra command.
Defaults
Enabled
Command Modes
INTERFACE
ipv6 neighbor
e
Configure a static entry in the IPv6 neighbor discovery.
Syntax
ipv6 neighbor {ipv6-address} {interface interface} {hardware_address}
To remove a static IPv6 entry from the IPv6 neighbor discovery, use the
no ipv6
neighbor
{ipv6-address} {interface interface} command.
milliseconds
Enter the leachability time in milliseconds.
Range: 0 to 3600000
