3.4.8 Checking the Configuration
You can view the configuration of IPv6 neighbor discovery.
Prerequisites
The configurations of the IPv6 neighbor discovery function are complete.
Procedure
l Run the display ipv6 neighbors [ ipv6-address | [ vid vlan-id ] interface-type interface-
number | vpn-instance vpn-instance-name ]display ipv6 neighbors interface-type
interface-number| [vid vid ] | [cevid cevid] command to check the neighbor information in
the cache.
l Run the display ipv6 interface [ interface-type interface-number | brief ] command to
check the IPv6 information of an interface. If the interface is in the Up state, the
configuration is successful.
----End
Example
Run the display ipv6 neighbors command. If the cache of the neighbor information contains
neighbors' IPv6 addresses and the specified interfaces, it means that the configuration succeeds.
