QuestionQ31

Layer 3 Fabrics

Which two statements are correct about IP fabrics that use unnumbered BGP?

Choose two
  • A Unnumbered BGP peering automatically provisions IPv4 peering.
  • B Unnumbered BGP requires that family inet6 is configured on each interface.
  • C Unnumbered BGP peering automatically provisions IPv6 peering.
  • D Unnumbered BGP requires that family inet is configured on each interface.
Explanation

Junos BGP unnumbered uses IPv6 Neighbor Discovery to discover directly connected peers and forms BGP sessions using IPv6 link-local addresses. Fabric-facing interfaces therefore require the inet6 address family. This mechanism establishes IPv6 peering automatically; it does not automatically provision IPv4 peering or require inet on every interface.
