[Yahoo-eng-team] [Bug 1490060] Re: kernel arp neighbor limits should be adjusted by l3 agent
[Expired for neutron because there has been no activity for 60 days.] ** Changed in: neutron Status: Incomplete => Expired -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1490060 Title: kernel arp neighbor limits should be adjusted by l3 agent Status in neutron: Expired Bug description: 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.
