Chapter 3 Configuring IPv6
Configuring IPv6
SUMMARY STEPS
1. config t
2. interface ethernet number
3. ipv6 nd
4. show ipv6 nd interface
5. copy running-config startup-config
DETAILED STEPS
This example shows how to configure IPv6 neighbor discovery reachable time:
switch# config t
switch(config)# interface ethernet 3/1
switch(config-if)# ipv6 nd reachable-time 10
This example shows how to display an IPv6 neighbor discovery interface:
switch(config-if)# show ipv6 nd interface ethernet 3/1
ICMPv6 ND Interfaces for VRF "default"
Ethernet3/1, Interface status: protocol-down/link-down/admin-down
IPv6 address: 0dc3:0dc3:0000:0000:0218:baff:fed8:239d
ICMPv6 active timers:
Last Neighbor-Solicitation sent: never
Last Neighbor-Advertisement sent: never
Last Router-Advertisement sent:never
Next Router-Advertisement sent in: 0.000000
Router-Advertisement parameters:
Periodic interval: 200 to 600 seconds
Send "Managed Address Configuration" flag: false
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
interface ethernet number
Example:
switch(config)# interface ethernet 2/31
switch(config-if)#
Enters interface configuration mode.
Step 3
ipv6 nd
Example:
switch(config-if)# ipv6 nd
Enables IPv6 neighbor discovery on the interface.
Step 4
show ipv6 nd interface
Example:
switch(config-if)# show ipv6 nd
interface
(Optional) Displays interfaces configured for IPv6
neighbor discovery.
Step 5
copy running-config startup-config
Example:
switch(config-if)# copy running-config
startup-config
(Optional) Saves this configuration change.
