Juniper Exam JN0-683 Topic 2 Question 27 Discussion

Understanding Unnumbered BGP:

Unnumbered BGP (Border Gateway Protocol) allows BGP peering between routers without assigning specific IP addresses to the interfaces. Instead, it uses the loopback address or another router identifier for the BGP session, making IP address management more straightforward in large-scale networks.

Family inet Configuration:

Option C: The family inet configuration is required on each interface involved in unnumbered BGP peering to support IPv4 address families. This ensures that IPv4 peering sessions can be established between devices.

Automatic IPv4 Peering:

Option D: Unnumbered BGP peering automatically provisions IPv4 peering sessions. This simplifies the configuration by eliminating the need to manually assign and manage IP addresses for BGP peering.

Conclusion:

Option C: Correct---Unnumbered BGP requires the family inet configuration for IPv4.

Option D: Correct---Unnumbered BGP automatically provisions IPv4 peering, simplifying setup.
