This post will use Cisco ASR9kV virtual routers running on a Cisco UCS chassis, mostly because Cisco currently have the leading-edge support for Segment-routing at this time, Juniper seem to be lagging behind a bit on that front!
Lets check out the topology;

It’s a pretty simple scenario – all of the routers in the topology are configured in the following way;

The first thing to look at here is BGP-LS “BGP Link-state” which is an extension of BGP that allows IGP information (OSPF/ISIS) to be injected into BGP, this falls conveniently into the world of centralised path computation – where we can use a controller of some sort to look at Continue reading
