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 ipv6 nd hop-limit hops Parameters • hop-limit hops - Enter the maximum number of hops allowed for RA messages (0 to 255). Defaults Command Mode Usage Information 64 hops INTERFACE The configured hop limit is advertised in RA messages and included in IPv6 data packets sent by the router. 0 indicates that no hop limit is specified by the router. 322 Layer 3
