Overview
NOTE: Before you read this chapter, we recommend you be thoroughly familiar with
both BGP and MPLS. For detailed information about those protocols, see “Configuring
BGP Routing” on page 3 and “Configuring MPLS” on page 275.
The BGP multiprotocol extensions (MP-BGP) enable BGP to support IPv4 services such
as BGP multicast and BGP/MPLS virtual private networks (VPNs). BGP/MPLS VPNs are
