Routing on the host refers to the notion of running a routing daemon on your host to directly advertise reachability from the host into the network fabric. Traditionally, this is done using Layer 2 technologies (VLANs, VXLANs) to segment L2 domains and put hosts in a specific VLAN with the ToR advertising subnet reachability. With software such as Quagga users can free users from the lock in of MLAG, help server load balancing via Anycast, and make VMs and Containers dynamically migratable across Datacenters without changing IP addresses.
