BGP Multipath Load Sharing for Both eBGP and
iBGP in an MPLS-VPN
iBGP in an MPLS-VPN
Part Number OL-10923-01 (Rev A0), June 26, 2006
The BGP Multipath Load Sharing for eBGP and iBGP feature allows you to configure multipath load
balancing with both external BGP (eBGP) and internal BGP (iBGP) paths in Border Gateway Protocol
(BGP) networks that are configured to use Multiprotocol Label Switching (MPLS) Virtual Private
Networks (VPNs). This feature provides improved load balancing deployment and service offering
capabilities and is useful for multi-homed autonomous systems and Provider Edge (PE) routers that
import both eBGP and iBGP paths from multihomed and stub networks.
