A.nothing,BGP automatically load-balances the traffic between different autonomous systems on all available links B.peer between the eBGP speaker’s loopbacks, configuring eBGP multihop as required, and use an IGP to load-share between the two equal-cost paths between the loopback addresses C.configure a loopback as update source for both EBGP peers and have on each AS an IGP to introduce two equal-cost paths to reach the EBGP peer loopback address;it is also necessary to use the next-hop-self command D.use the ebgp-load-balance command on the neighbor statement on both sides E.configure a loopback as update source for both EBGP peers and have on each AS an IGP to introduce two equal-cost paths to reach the peer loopback address;it is also necessary to use the ebgp-multihop and next-hop-self commands
A.prefixes received from any other BGP peer and prefixes locally originated via networkstatements or redistributed B.all prefixes in its routing table C.prefixes received from EBGP peers and prefixes locally originated via network statements or redistributed D.prefixes received from EBGP peers and prefixes received from route reflectors E.prefixes received from other IBGP peers, prefixes received from EBGP peers,and prefixes redistributed to BGP F.prefixes received from other IBGP peers and prefixes received from route reflectors
