Unlike IPv4, the IPv6 default gateway can have multiple IPv6 addresses which may include up to
one user-defined static address and multiple dynamic addresses learned via router solicitation
message. The user-defined default gateway has a higher precedence over an automatically
advertised router.
When removing an IP interface, all of its default gateway IP addresses are removed. Dynamic IP
addresses cannot be removed. An Alert message appears once a user attempts to insert more than
one user-defined address. An Alert message appears when attempting to insert a none Link Local
type address.
This editor has the following fields:
-
Gateway IP —Displays the Link Local IPv6 address of the default gateway.
-
Interface —Specifies the outgoing interface through which the default gateway can be reached.
Interface refers to any Port/LAG/VLAN and/or Tunnel.
-
Ty p e —Specifies the means by which the default gateway was configured. The possible field
values are:
Static—Indicates the default gateway is user-defined.
Dynamic—Indicates the default gateway is dynamically configured.
- State —Displays the default gateway status. The possible field values are:
Incomplete—Indicates that address resolution is in progress and the link-layer address of the
default gateway has not yet been determined.
Reachable—Indicates that the default gateway is known to have been reachable recently
(within the last tens of seconds).
Stale—Indicates that the default gateway is no longer known to be reachable but until traf-
fic is sent to the default gateway, no attempt is made to verify its reachability.
Delay—Indicates that the default gateway is no longer known to be reachable, and traffic
has recently been sent to the default gateway. Rather than probe the default gateway
immediately, however, there is a delay sending probes for a short while in order to give
upper-layer protocols a chance to provide reachability confirmation.
Probe—Indicates that the default gateway is no longer known to be reachable, and unicast
Neighbor Solicitation probes are being sent to verify reachability.
Unreachable—Indicates that no reachability confirmation was received.
