COMMAND USAGE
◆ 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 enabled
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
IPv6 link MTU is 1500 bytes.
ND DAD is enabled, number of DAD attempts: 5.
ND retransmit interval is 1000 milliseconds
ND advertised retransmit interval is 0 milliseconds
ND reachable time is 30000 milliseconds
ND advertised reachable time is 0 milliseconds
