ipv6 opportunistic-nd

Overview Use this command to enable opportunistic neighbor discovery for the global IPv6
ND cache. Opportunistic neighbor discovery changes the behavior for unsolicited
ICMPv6 ND packet forwarding on the device.
Use the no variant of this command to disable opportunistic neighbor discovery
for the global IPv6 ND cache.
ipv6 opportunistic-nd
Syntax
no ipv6 opportunistic-nd
Default Opportunistic neighbor discovery is disabled by default.
Mode Global Configuration
Usage When opportunistic neighbor discovery is enabled, the device will reply to any
received unsolicited ICMPv6 ND packets. The source MAC address for the
unsolicited ICMPv6 ND packet is added to the IPv6 ND cache, so the device
forwards the ICMPv6 ND packet. When opportunistic neighbor discovery is
disabled, the source MAC address for the ICMPv6 packet is not added to the IPv6
ND cache, so the ICMPv6 ND packet is not forwarded by the device.
Examples To enable opportunistic neighbor discovery for the IPv6 ND cache, enter:
awplus#
awplus(config)#
To disable opportunistic neighbor discovery for the IPv6 ND cache, enter:
awplus#
awplus(config)#
