ofagent l2pop support¶
https://blueprints.launchpad.net/neutron/+spec/ofagent-l2pop
implement l2pop support for ofagent agent.
Problem description¶
- many packets sent to tunnels because of:
tenant unawareness; no need to forward a packet to nodes which doesn’t run endpoints (typically VMs) belonging to the tenant.
broadcasts, namely arp requests
see L2population_blueprint for more discussions.
Proposed change¶
implement l2pop-based tunnel management as it’s done in ovs
implement local arp responder by handling packet-ins
Alternatives¶
local arp responder part can be implemented differently. for example, using nicira extensions as described in Ovs-flow-logic. however it isn’t a choice for ofagent as there’s no way to implement such a flow-based arp responder without vendor extensions.
