Yes...the reason why is because external BGP must be able to reach the
NEXT_HOP. With IBGP this is done with a recursive route lookup using
the IGP, but it is not customary to run an IGP between ASs. Therefore
EBGP requires that the peers share the same subnet.

// I ask a question. Why should we use EBGP-MULTIHOP? Is EBGP send packet with
TTL=1 in default and EBGP-MULTIHOP will affect the TTL?
