Configuring IPv6 for Gigabit Ethernet Interfaces
Purpose
Sets the duplicate address detection attempts
count to 100. The range is 0 to 15.
Reverts to the default value (0).
Note
When the attempt count is set to 0,
neighbor discovery is disabled.
Purpose
Enters configuration mode.
Specifies an interface and enters interface
configuration submode.
Sets the reachability time to 10000 milliseconds.
The range is 1000 to 3600000 milliseconds.
Reverts to the default value (30000
milliseconds).
Purpose
Enters configuration mode.
Specifies an interface and enters interface
configuration submode.
Sets the retransmission time to 20000
milliseconds. The range is 1000 to 3600000
milliseconds.
Reverts to the default value (1000 milliseconds).
