IPv6 Default Router List

The IPv6 Default Router List page enables configuring and viewing the default IPv6 router addresses. This list contains the routers that are candidates to become the device default router for non-local traffic (it may be empty). The device randomly selects a router from the list. The device supports one static IPv6 default router. Dynamic default routers are routers that have sent router advertisements to the device IPv6 interface.

When adding or deleting IP addresses, the following events occur:

  • When removing an IP interface, all the default router IP addresses are removed. Dynamic IP addresses can’t be removed.

  • An alert message appears after an attempt is made to insert more than a single user-defined address.

  • An alert message appears when attempting to insert a non-link local type address, meaning 'fe80:'.

To define a default router, complete the following:

Procedure


Step 1

Click IPv6 Configuration > IPv6 Default Router List.

This page displays the following fields for each default router:

  • Outgoing Interface—Outgoing IPv6 interface where the default router resides.

  • Default Router IPv6 Address—Link local IP address of the default router.

  • Type—The default router configuration that includes the following options:

    • Static—The default router was manually added to this table through the Add button.

    • Dynamic—The default router was dynamically configured.

    • Neighbor Discovery (ND)—The default router is set to ND. Neighbor Discovery Protocol is used to identify the relationships between the different neighboring devices in an IPv6 network.

  • Metric—Cost of this hop.

Step 2

Click Add to add a static default router.

Step 3

Enter the following fields:

  • Next Hop Type—The IP address of the next destination to which the packet is sent. This is composed of the following:

    • Global—An IPv6 address that is a global Unicast IPV6 type that is visible and reachable from other networks.

    • Link Local—An IPv6 interface and IPv6 address that uniquely identifies hosts on a single network link. A link local address has a prefix of FE80, isn’t routable, and can be used for communication only on the local network. Only one link local address is supported. If a link local address exists on the interface, this entry replaces the address in the configuration.

  • Outgoing Interface—Displays the outgoing Link Local interface.

  • Default Router IPv6 Address—The IP address of the static default router

  • Metric—Enter the cost of this hop.

Step 4

Click Apply. The default router is saved to the Running Configuration file.
