Configuring IPv6 First Hop Security
SUMMARY STEPS
1. configure terminal
2. [no] ipv6 neighbor binding [vlan vlan-id {ipv6-address interface interface_type stack/module/port
hw_address [reachable-lifetimevalue [seconds | default | infinite] | [tracking{ [default | disable] [
reachable-lifetimevalue [seconds | default | infinite] | [enable [reachable-lifetimevalue [seconds |
default | infinite] | [retry-interval {seconds| default [reachable-lifetimevalue [seconds | default | infinite]
} ]
3. [no] ipv6 neighbor binding max-entries number [mac-limit number | port-limit number [mac-limit
number] | vlan-limit number [ [mac-limit number] | [port-limit number [mac-limitnumber] ] ] ]
4. ipv6 neighbor binding logging
5. exit
6. show ipv6 neighbor binding
DETAILED STEPS
Command or Action
Step 1
configure terminal
Example:
Switch# configure terminal
Step 2 [no] ipv6 neighbor binding [vlan vlan-id {ipv6-address interface
interface_type stack/module/port hw_address [reachable-lifetimevalue
[seconds | default | infinite] | [tracking{ [default | disable] [
reachable-lifetimevalue [seconds | default | infinite] | [enable
[reachable-lifetimevalue [seconds | default | infinite] | [retry-interval
{seconds| default [reachable-lifetimevalue [seconds | default | infinite]
} ]
Example:
Switch(config)#
Step 3 [no] ipv6 neighbor binding max-entries number [mac-limit number |
port-limit number [mac-limit number] | vlan-limit number [ [mac-limit
number] | [port-limit number [mac-limitnumber] ] ] ]
Example:
Switch(config)#
Step 4
ipv6 neighbor binding logging
Example:
Switch(config)# ipv6 neighbor binding logging
Step 5 exit
Example:
Switch(config)# exit

How to Configure the IPv6 Binding Table Content
Purpose
Enters the global configuration mode.
Specifies the maximum number of entries
that are allowed to be inserted in the
binding table cache.
Enables the logging of binding table main
events.
Exits global configuration mode, and
places the router in privileged EXEC
mode.
