Use undo ipv6 neighbors max-learning-num to restore the default.
By default, a Layer 2 interface does not limit the number of neighbors dynamically learned. A Layer 3
interface can learn up to 1024 neighbors dynamically.
Examples
# Set the maximum number of neighbors that can be dynamically learned on GigabitEthernet 0/1 to 10.

Parameters
vpn-instance vpn-instance-name: Specifies the VPN for which the path MTU is to be displayed. The
vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. Without this option specified,
the command displays the path MTU for the public network.
ipv6-address: IPv6 address.
value: Path MTU of a specified IPv6 address, ranging from 1280 to 10000 bytes.
Description
Use ipv6 pathmtu to configure a static path MTU for a specified IPv6 address.
Use undo ipv6 pathmtu to remove the path MTU configuration for a specified IPv6 address.
By default, no static path MTU is configured.
Examples
# Configure a static path MTU for a specified IPv6 address.
