IPv6 Interface
– 945 –
COMMAND USAGE
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.
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 enable.
Link-local address:
FE80::200:E8FF:FE90:0/64
Global unicast address(es):
2009:DB9:2229::79, subnet is 2009:DB9:2229:0::/64
Joined group address(es):
FF01::1/16
FF02::1/16
FF02::1:FF00:79/104
FF02::1:FF90:0/104
MTU is 1500 bytes.
ND DAD is enabled, number of DAD attempts: 5.
ND retransmit interval is 30000 milliseconds

ipv6 nd reachable-
time
This command configures the amount of time that a remote IPv6 node is
considered reachable after some reachability confirmation event has
occurred.
SYNTAX
ipv6 nd reachable-time milliseconds
no ipv6 nd reachable-time
milliseconds - The time that a node can be considered reachable
after receiving confirmation of reachability.
(Range: 1000-3600000)
DEFAULT SETTING
30000 milliseconds is used for neighbor discovery operations
