ipv6 opportunistic-nd
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 switch.
Use the no variant of this command to disable opportunistic neighbor discovery for the
global IPv6 ND cache.
Syntax
ipv6 opportunistic-nd
no ipv6 opportunistic-nd
Default
Opportunistic neighbor discovery is disabled by default.
Mode
Global Configuration
Usage
When opportunistic neighbor discovery is enabled, the switch 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 switch 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 switch.
Examples
