Purpose
Enables IS-IS routing for the specified routing process, and
places the router in router configuration mode.
• By default, all IS-IS instances are automatically Level 1
and Level 2. You can change the level of routing to be
performed by a particular routing instance by using the
is-type command.
Enters interface configuration mode.
Specifies the IPv4 address family and enters router address
family configuration mode.
Enables MPLS LDP synchronization for the IPv4 address
family under interface GigabitEthernet 0/1/0/3.
