A data center interconnect using a VXLAN was recently implemented.

VXLAN (Virtual Extensible LAN) encapsulates Ethernet frames inside UDP packets, increasing packet size. This can lead to fragmentation and performance degradation unless Jumbo Frames are enabled.

Breakdown of Options:

A. 802.1Q tagging – VLAN tagging enables segmentation but does not address fragmentation issues.

B. Spanning tree – STP prevents loops but does not improve performance for VXLAN traffic.

C. Link aggregation – LACP combines links for higher bandwidth but does not prevent fragmentation.

D. Jumbo frames – Correct answer. Enabling Jumbo Frames allows larger packet sizes, reducing fragmentation and improving VXLAN performance.
