v1.15.28 (2026-09-22)

This release restores the historical underlay ARP flood option so broadcast ARP/ND probes do not exceed the OVS 4096 resubmit limit.

Changes

• acc9b247d Restore bcast_arp_req_flood with default false. The MC_UNKNOWN northd change only rewrites router-IP ARP/ND; underlay VIF ARP probes can still flood and exceed the 4096 resubmit limit. With the option disabled, broadcast ARP requests skip L2 flood and localnet ARP for known LSP IPs is unicast-forwarded.
