Command Mode Usage Information INTERFACE • Use this command to enable local processing of IPv6 packets with hop-by-hop options in conformance with RFC 8200, IPv6 Specification. • The no version of this command disables IPv6 processing of hop-by-hop header options. Example: Disable hop-by-hop option processing OS10(config)# interface ethernet 1/2/3 OS10(conf-if-eth1/2/3)# no ipv6 hop-by-hop Supported Releases 10.4.0E(R1) or later ipv6 nd dad Disables or re-enables IPv6 duplicate address discovery (DAD). Syntax ipv6 nd dad {disable | enable | disable-ipv6-on-dad-failure} Parameters • disable - Disable duplicate address discovery on the interface. • enable - Re-enable IPv6 duplicate address discovery if you have disabled it. • disable-ipv6-on-dad-failure - Enable duplicate address discovery on the existing autoconfigured link-local address. Defaults Command Mode Usage Information Duplicate address discovery is enabled on an interface. INTERFACE • An OS10 switch sends a neighbor solicitation message to determine if an autoconfigured IPv6 unicast link-local address is unique before assigning it to an interface. If the process of duplicate address discovery (DAD) detects a duplicate address in the network, the link-local address is not configured. Other IPv6 addresses are still active on the interface. • By default, DAD does not disable IPv6 if a duplicate link-local address is detected in the network. To disable IPv6 on an interface when a duplicate link-local address is detected, use the ipv6 nd dad disableipv6-on-failure command. Example: Disable DAD OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ipv6 nd dad disable Example: Enable DAD on link-local address OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ipv6 nd dad disable-ipv6-on-dad-failure Supported Releases 10.4.0E(R1) or later ipv6 nd hop-limit Sets the hop limit advertised in RA messages and included in IPv6 data packets sent by the router. Syntax Parameters ipv6 nd hop-limit hops • hop-limit hops - Enter the maximum number of hops allowed for RA messages (0 to 255). Defaults 64 hops 342 Layer 3
