Layer 3 Fabrics

Which protocol enables the greatest scalability for an IP underlay fabric?

  • A RIP
  • B RSVP
  • C VXLAN
  • D EBGP
Explanation

eBGP scales well in large IP underlay fabrics because it is designed for policy-based interdomain-style routing, supports route aggregation and multipath designs, and avoids the flooding behavior associated with link-state routing protocols. VXLAN is an overlay encapsulation rather than an underlay routing protocol.
