address-family labeled-unicast
Use the address family command to enter the IPv4 or VPNv4 address family mode allowing configuration of address-family specific parameters. To leave address family mode and return to configure mode, give the
exit-address-family command.
This command configures the routing exchange between Provider Edge (PE) and Customer Edge (CE) devices. The BGP sessions between PE routers can carry different types of routes (VPN-IPv4 and IPv4 routes). Address families are used to control the type of BGP session.
Use the no parameter with this command to disable the address-family configurations.
