Purpose
Specifies the IPv6 address family and enters router address family
configuration mode.
• This example specifies the unicast IPv6 address family.
(Optional) Configures the link topology for IPv4 when IPv6 is
configured.
• The single-topology command is valid only in IPv6 submode.
The command instructs IPv6 to use the single topology rather
than the default configuration of a separate topology in the
multitopology mode.
• See the Single-Topology IPv6 Support, on page 278
information.
Exits router address family configuration mode, and returns the router
to router configuration mode.
Enters interface configuration mode.
(Optional) Configures the type of adjacency.
• The default circuit type is the configured system type (configured
through the is-type command).
• Typically, the circuit type must be configured when the router is
configured as only level-1-2 and you want to constrain an
interface to form only level-1 or level-2-only adjacencies.
Specifies the IPv4 or IPv6 address family, and enters interface address
family configuration mode.
• This example specifies the unicast IPv4 address family on the
interface.
(Optional) Displays information about the IS-IS interface.
