Rama Darbha - shares with us a demo on using Ansible to set up Cumulus Routing on the Host

https://github.com/CumulusNetworks/cldemo-roh-ansible

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.

This demo is written for the cldemo-vagrant reference topology and applies the reference BGP unnumbered configuration from cldemo-config-routing.
