IPv6 Interface
– 685 –
Command Usage
â—†
When a non-default value is configured, the specified interval is used both for
router advertisements and by the router itself.
â—†
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.
â—†
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)#ipv6 nd ns-interval 30000
Console(config)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enabled
