1.2.4.7.2 Neighbor Discovery Protocol (NDP) Configurations

NDP Specific User Configurations

  • NDP Task Rate (in msec):

    • NDP task processing rate, in milliseconds.
    • The NDP module will process a timer event with this rate for maintaining its own queues, processing timeouts, etc.
    • The lower the rate (higher the frequency) the higher the module priority and higher module performance can be obtained
    • The value cannot be lower than the TCPIP_STACK_TICK_RATE.
    • Value is in milliseconds
    • Default value: 32
    • Symbol TCPIP_NDP_TASK_TIMER_RATE, TCPIP_IPV6_NDP_TASK_TIMER_RATE

  • RTR Solicitation Delay (in sec):

    • Router Solicitation Delay
    • Value is in seconds
    • Default value: 1
    • Symbol TCPIP_MAX_RTR_SOLICITATION_DELAY, TCPIP_IPV6_NDP_MAX_RTR_SOLICITATION_DELAY

  • RTR Solicitation Interval (in sec):

    • Router Solicitation Interval
    • Value is in seconds
    • Default value: 4
    • Symbol TCPIP_RTR_SOLICITATION_INTERVAL, TCPIP_IPV6_NDP_RTR_SOLICITATION_INTERVAL

  • Maximum RTR Solicitations:

    • Maximum number of router solicitations
    • Default value: 3
    • Symbol TCPIP_MAX_RTR_SOLICITATIONS, TCPIP_IPV6_NDP_MAX_RTR_SOLICITATIONS

  • Maximum Multicast Solicitations:

    • Maximum number of multicast solicitations
    • Default value: 3
    • Symbol TCPIP_MAX_MULTICAST_SOLICIT, TCPIP_IPV6_NDP_MAX_MULTICAST_SOLICIT

  • Maximum Unicast Solicitations:

    • Maximum number of unicast solicitations
    • Default value: 3
    • Symbol TCPIP_MAX_UNICAST_SOLICIT, TCPIP_IPV6_NDP_MAX_UNICAST_SOLICIT

  • Maximum Anycast Delay Time (in sec):

    • Maximum anycast delay time
    • Value is in seconds
    • Default value: 1
    • Symbol TCPIP_MAX_ANYCAST_DELAY_TIME, TCPIP_IPV6_NDP_MAX_ANYCAST_DELAY_TIME

  • Maximum Neighbor Advertisement Transmissions:

    • Maximum number of neighbor advertisement transmissions
    • Default value: 3
    • Symbol TCPIP_MAX_NEIGHBOR_ADVERTISEMENT, TCPIP_IPV6_NDP_MAX_NEIGHBOR_ADVERTISEMENT

  • Reachable Time (in sec):

    • Value for the reachable time
    • Value is in seconds
    • Default value: 30
    • Symbol TCPIP_REACHABLE_TIME, TCPIP_IPV6_NDP_REACHABLE_TIME

  • Re-transmission Timer (in sec):

    • Value of the retransmission timer
    • Value is in seconds
    • Default value: 1
    • Symbol TCPIP_RETRANS_TIMER, TCPIP_IPV6_NDP_RETRANS_TIMER

  • Delay First Probe Time (in sec):

    • Value of the delay for the first probe
    • Value is in seconds
    • Default value: 5
    • Symbol TCPIP_DELAY_FIRST_PROBE_TIME, TCPIP_IPV6_NDP_DELAY_FIRST_PROBE_TIME

  • IPv6 MTU Increase Time-out (in sec):

    • Sets the maximum transmit unit increase timeout
    • Value is in seconds
    • Default value: 600
    • Symbol TCPIP_IPV6_MTU_INCREASE_TIMEOUT
