Implementing BGP in MPLS VPNs

BGP, though considered a complex routing protocol, is widely used for PE-CE routing in MPLS VPN networks. In prior chapters, you were introduced to various facets of configuring IGP PE-CE routing in MPLS VPN networks. This chapter explains BGP PE-CE routing and its configuration and utilization in an MPLS VPN environment.

The following BGP concepts are discussed:

• BGP PE-CE routing protocol overview, configuration, and verification
• BGP route-reflectors in an MPLS VPN environment
• BGP peer groups
• BGP confederations in an MPLS VPN environment
