Command Reference Guide
ipv6 nd ra reachable-time <value>
Use the ipv6 nd ra reachable-time command to specify the value advertised for reachable time in Internet
Protocol version 6 (IPv6) router advertisement (RA) messages. This command also specifies the internal
base reachable time used by the router. This command is effectual for interfaces in either host or router
mode. Use the no form of this command to return the reachability value to the default setting.
Syntax Description
<value>
Default Values
By default, the router advertises a reachability time of 0 ms and uses an internal value of 30000 ms.
Command History
Release 18.1
Functional Notes
This command is effectual for interfaces in either router or host mode. For hosts, this value sets the internal
reachable time used by the host if no RAs are received specifying a different value. For routers, the value
indicates the amount of time a device is considered reachable after having received a reachability
confirmation in neighbor unreachabililty detection (NUD).
Usage Examples
The following example specifies that a reachability time of 50000 ms is advertised in RA messages:
(config)#interface frame-relay 1.16
(config-fr 1.16)#ipv6 nd ra reachable-time 50000
60000CRG0-35E
Specifies the reachability time in milliseconds. Range is 0 to 3600000 ms. A
value of 0 indicates the reachable time is unspecified.
Command was introduced.
