Configure Reachable Time for Remote IPv6 Nodes

Router advertisement messages include a reachable time value. All nodes on a link use the same value. By default, the reachable time duration is 0.

Extreme recommends that you configure a long duration, because a short duration causes IPv6 network devices to process the information at a greater frequency.

  1. Access global configuration mode.
    device# configuration terminal
  2. Access interface configuration mode.
    device(config)# interface ethernet 0/1
  3. Configure the reachable time.
    device(conf-if-eth-0/1)# ipv6 nd reachable-time 600
    
    Note

    Note

    The actual reachable time ranges from 0.5 to 1.5 times the configured or default value.
