IPv6 only BGP/OSPF/RIPNG/ISIS lab with FRRouting
This lab has been done with BSDRP under bhyve and it show an example of BGP/ISIS/RIPNG/OSPF interactions with IPv6 only.

Here is the logical and physical view:
Description and limitations
This lab has been done to improve IPv6 use and routing experience. The routers have been configured int the simpliest way. No authentication or log have been configured (and this is bad !!!)
I also tried to make some “funnies” BGP interconnections. - The IGP protocol do not send routes to the EGP protocol - Inside an area, BGP border routers exchange their routes
The LAB_v6only_GW is a router used to make an interconnexion with a global lab network
The host are not described here but a simple host vith ipv6 auto-configuration is enough
Setting-up the lab
Downloading BSD Router Project images
Download BSDRP serial image (prevent to have to use an X display) on Sourceforge.
Configure lab with netlab
Quick installation of netlab
Pull the repository https://github.com/stardco/netlab.git In root mode :
make install
