ipv6 nd ra-lifetime e Configure the router lifetime value in the IPv6 router advertisements on an interface. The description of router lifetime from RFC 2461(http://tools.ietf.org/html/rfc2461) is: Router Lifetime: 16-bit unsigned integer. The lifetime associated with the default router in units of seconds. The maximum value corresponds to 18.2 hours. A Lifetime of 0 indicates that the router is not a default router and SHOULD NOT appear on the default router list. The Router Lifetime applies only to the router's usefulness as a default router; it does not apply to information contained in other message fields or options. Options that need time limits for their information include their own lifetime fields. Syntax ipv6 nd ra-lifetime seconds To restore the default values, use the no ipv6 nd ra-lifetime command. Parameters seconds Enter the lifetime value in seconds. Range: 0 to 9000 Defaults 9000 seconds Command Modes INTERFACE 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 milliseconds Enter the leachability time in milliseconds. Range: 0 to 3600000 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. Neighbor Discovery Protocol (NDP) | 981
