Purpose
Enters global configuration mode.
Enters interface configuration mode for the bundle-interface.
Disables arp learning for the access-interface.
Enables IPv4 processing on a unnumbered interface without assigning
an explicit IPv4 address to that interface. Instead, the IP address is
borrowed from the loopback interface. For the "ipv4 unnumbered"
command, you must specify another interface in the same router that has
been assigned an IP address and whose status is displayed as "up" for the
show interfaces command.
Enables IPv6 processing on an unnumbered interface that has not been
assigned an explicit IPv6 address.
This step not only enables IPv6 processing on the interface, but
Note
also assigns an IPv6 link-local unicast address to it.
commit—Saves the configuration changes and remains within the
configuration session.
end—Prompts user to take one of these actions:
• Yes— Saves configuration changes and exits the configuration
session.
• No—Exits the configuration session without committing the
configuration changes.
• Cancel—Remains in the configuration mode, without committing
the configuration changes.
