Routing On the Host (RoH) Demo
This demo shows a topology using 'Routing on the Host' to add host reachability directly into a BGP routed fabric. Switches are Cumulus Linux and servers running Ubuntu. This playbook configures a CLOS topology running BGP unnumbered in the fabric with numbered links towards the hosts, and installs a webserver on one of the hosts to serve as a Hello World example. The Ubunut server acts as the host to redistribute kernel routes as /32 host routes into the routing table when VMs or containers become available. When the demo runs successfully, any server on the network should be able to access the webserver via the BGP routes established over the fabric.
Quickstart: Run the demo
