You have two EBGP peers connected via two parallel serial lines. What should you do to be able to load-balance between two EBGP speakers over the parallel serial lines in both directions？ （） nothing，BGP automatically load-balances the traffic between different autonomous systems on all available links。 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。 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。 use the ebgp-load-balance command on the neighbor statement on both sides。 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 command。
