• Configuring a new default GW without deleting the previous configured information overwrites the
previous configuration.
• A configured default GW has a higher precedence over automatically advertised (via router
advertisement message).
• If the egress interface is not specified, the default interface will be selected. Specifying interface
zone=0 is equal to not defining an egress interface.
Example
The following example defines an IPv6 default gateway.
