- The document discusses Neutron L3 HA (VRRP) and summarizes a presentation given on the topic.
- Neutron L3 HA uses the VRRP protocol to provide redundancy and failover for virtual routers across multiple network nodes. A heartbeat network is created for each tenant using their tenant network.
- When a router is created, a heartbeat port and interface are created on each L3 agent node using the tenant's heartbeat network to enable communication between the agents for the VRRP implementation.
