Routing Fundamentals

A customer uses a Clos IP-fabric design in its data center.

What advantage does EBGP signaling between spine and leaf nodes provide instead of IBGP in this scenario?

  • A An EBGP router automatically performs the next hop self-operation on advertised routes.
  • B By default, EBGP supports multihop sessions between peers.
  • C A leaf node can have multiple EBGP sessions with a spine node.
  • D EBGP does not require support for the ADD-PATH capability.
Explanation

EBGP advertisements use the advertising router as the next hop by default, so routes exchanged across directly connected spine-to-leaf links have a reachable next hop without the additional next-hop resolution typically needed for IBGP-learned routes.
