C HAPTER 46 | IP Interface Commands
Neighbor Discovery
– 1454 –
COMMAND USAGE
◆ When a non-default value is configured, the specified interval is used
both for router advertisements and by the router itself.
◆ This command specifies the interval between transmitting neighbor
solicitation messages when resolving an address, or when probing the
reachability of a neighbor. Therefore, avoid using very short intervals
for normal IPv6 operations.
◆ Setting the neighbor solicitation interval to 0 means that the configured
time is unspecified by this router.
EXAMPLE
The following sets the interval between sending neighbor solicitation
messages to 30000 milliseconds:
Console(config)#interface vlan 1
Console(config)#pv6 nd ns-interval 30000
Console(config)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enabled
