IPv6 Routing Configuration

About this task

Procedure

  1. Select the IPv6 Routing tab.

    IPv6 networks are connected by IPv6 routers. IPv6 routers pass IPv6 packets from one network segment to another.

    The IPv6 Routing configuration screen displays.

  2. Select Unicast Routing to enable IPv6 unicast routing for this profile. Keeping unicast enabled allows the profile‘s neighbor advertisements and solicitations in unicast (as well as multicast) to provide better neighbor discovery. This setting is enabled by default.
  3. Select Unique Local Address Reject Route to enable rejecting local routes in the format FC00::/7.
  4. Set a System NS Retransmit Interval (from 1,000 to 3,600,000 milliseconds) as the interval between NS (neighbor solicitation) messages. NS messages are sent by a node to determine the link layer address of a neighbor, or verify a neighbor is still reachable via a cached link-layer address. The default is 1,000 milliseconds.
  5. Set a System ND Reachable Time (from 5,000 to 3,600,000 milliseconds) as the time a neighbor is assumed to be reachable after receiving a receiving a ND (neighbor discovery) confirmation for their reachability. The default is 30,000 milliseconds.
  6. Set an IPv6 Hop Count (from 1 - 255) as the maximum number of hops considered valid when sending IP packets. The default setting is 64.
  7. Set the following Router Advertisement Conversion to Unicast settings:

    RA Convert (milliseconds)

    Select this option to convert multicast router advertisements (RA) to unicast router advertisements at the dot11 layer. Unicast addresses identify a single network interface, whereas a multicast address is used by multiple hosts. This setting is disabled by default.

    Throttle

    Select this option to throttle RAs before converting to unicast. Once enabled, set the throttle interval and maximum number of RAs. This setting is disabled by default.

    Throttle Interval (milliseconds)

    Enable this setting to define the throttle interval (3 - 1,800 seconds). The default setting is 3 seconds.

    Max RAs

    Enable this setting to define the maximum number of router advertisements per router (1 - 256) during the throttle interval. The default setting is 1.
  8. In the IPv6 Routes table, click + Add Row and add additional 256 IPv6 route resources.

    The IPv6 static route Add Row screen displays.

    Network Address

    Set the IPv6 network address. Other than the length and slightly different look versus an IPv4 address, the IPv6 address concept is same as IPv4.

    Gateway

    Set the IPv6 route gateway. A network gateway in IPv6 is the same as in IPv4. A gateway address designates how traffic is routed out of the current subnet.

    Interface

    If using a link local address, set the VLAN (1 - 4,094) used a virtual routing interface for the local address.
  9. Select OK to save the IPv6 static route changes.

    Select Reset to revert to the last saved configuration.
