#
# This test is for checking bridge neighbor suppression functionality. The
# topology consists of two bridges (VTEPs) connected using VXLAN. A single
# host is connected to each bridge over multiple VLANs. The test checks that
# ARP/NS messages from the first host are suppressed on the VXLAN port when
# should.

- Atlas domain: Support Tooling And Documentation / tools.

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
