v1.15.29 (2026-09-24)
This release stops underlay IPv6 neighbor solicitations from flooding L2, so ARP/ND probes do not exceed the OVS 4096 resubmit limit.
Changes
dcd55969aAvoid flooding IPv6 neighbor solicitations in underlay. Rename the OVN NB option tobcast_arp_nd_req_flood, send(eth.bcast && arp.op == 1) || nd_ns_mcastthrough the unknown-destination path instead ofMC_FLOOD_L2, and rely on OVN's native localnet ARP/ND responder instead of the old priority 110 localnet-to-known-LSP forwarding flows.
