Public bug reported: The default neighbor limits can be quite low (1024) for a kernel that the l3 agent is running on. If the agent is serving hundreds of tenants, it can quite easily blow past this limit, causing contention for a spot in the ARP table (or neighbor table in IPv6) and network instability.
The l3 agent should set a higher default to match the expectations of a node with an l3 agent on it. ** Affects: neutron Importance: Undecided Assignee: Kevin Benton (kevinbenton) Status: New ** Changed in: neutron Assignee: (unassigned) => Kevin Benton (kevinbenton) -- You received this bug notification because you are a member of Yahoo!
