Defining an 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 switch default router for non-local traffic (it may be empty). The switch randomly selects a router from the list. The switch supports one static IPv6 default router. Dynamic default routers are routers that have sent router advertisements to the switch 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 cannot be removed.
- An alert message is displayed after an attempt is made to insert more than a single user-defined address.
- An alert message is displayed when attempting to insert a non-link local type address, meaning 'fe80:'.
To define a default router:
- In Layer 2 mode, click Administration > Management Interface > (Layer 2) > IPv6 Default Router List.
In Layer 3 mode, click IP Configuration > Management and IP Interface > IPv6 Default Router List.The IPv6 Default Router List page opens.
This page displays the following fields for each default router:
- Default Router IPv6 Address--Link local IP address of the default router.
- Interface--Outgoing IPv6 interface where the default router resides.
- Type--The default router configuration that includes the following options:
State--The default router status options are:
- Incomplete--Address resolution is in process. Default router has not yet responded.
- Reachable--Positive confirmation was received within the Reachable Time.
- Stale--Previously-known neighboring network is unreachable, and no action is taken to verify its reachability until it is necessary to send traffic.
- Delay--Previously-known neighboring network is unreachable. The device is in Delay state for a predefined Delay Time. If no confirmation is received, the state changes to Probe.
- Probe--Neighboring network is unavailable, and Unicast Neighbor Solicitation probes are being sent to verify the status.
- Click Add to add a static default router. The Add Default Router page opens.
The window displays the Link Local Interface. The interface can be a port, LAG, VLAN, or tunnel.
- Enter the static default router IP address in the Default Router IPv6 Address field.
- Click Apply. The default router is defined, and the Running Configuration file is updated.
