Hello,
Please refer to the following resources as the answer to this question needs to be reconsidered as multipath not multihop:
http://www.cisco.com/en/US/tech/tk365/te...l#bgpmpath
BGP Multipath allows installation into the IP routing table of multiple BGP paths to the same destination. These paths are installed in the table together with the best path for load sharing
http://www.cisco.com/en/US/docs/ios/12_2...eibmp.html
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.
22. (QID:NF76) Which BGP option is required when load sharing over multiple equal-bandwidth parallel links from a single CE router to a single ISP router over eBGP?
eBGP Multipath
eBGP Multihop
BGP Synchronization
Public AS numbers
Correct Answer: eBGP Multihop
