FWIW, we have cloned the router plugin in here in our own project https://github.com/FDio/hicn/tree/master/extras/router-plugin tested in ubuntu 18LTS and FRR with BGP and OSPF. BGP works for IPv4 and IPv6. OSPF IPv4 works fine while IPv6 does not work because there is a VPP issue on ND and multicast that we did were unable to fix. The ND issue may be just related to the VMware ESXi environment we were using and may not show up in other platforms.
I'll share some more info in the doc later on how we manage to configure and use the plugin with FRR.
