Default Configuration
No default gateway is defined.
Command Mode
Global Configuration mode
User Guidelines
The format of an IPv6Z address is: {ipv6-link-local-address>%<
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). Precedence takes effect once the configured default GW is reachable.
Reachability state is not verified automatically by the neighbor discovery protocol.
Router reachability can be confirmed by either receiving Router Advertisement
message containing router's MAC address or manually configured by user using
the IPv6 neighbor CLI command. Another option to force reachability confirmation
is to ping the router link-local address (this will initiate the neighbor discovery
process).
If the egress interface is not specified, the default interface is selected. Specifying
interface zone=0 is equal to not defining an egress interface.
Example
console(config)# ipv6 default-gateway fe80::abcd
