We can see the routes that SDN-IP has learnt with the "routes" command.

Code Block
onos> routes

prefix=       
   192.168.3.0/24, nexthop=     10.0.3.1       
Total SDN-IP routes = 3

Don't worry if you don't see all of the routes straight away - sometimes it takes a minute or so for the BGP sessions to establish and advertise the routes to ONOS.

We see a total of 27 intents. The 24 PointToPointIntents are simple end-to-end flows which allow the external BGP routers to communicate with our internal BGP speaker. The three MultiPointToSinglePoint intents are the forwarding rules for the routes that we've learned through BGP. Each route is translated into one MultiPointToSinglePoint intent which matches the traffic for that route at the ingress ports of the network and forwards it along to the router who advertised the route to us. This is how we use routing information learned from BGP to enable traffic to transit our network on these routes.

Let's go back to our ONOS terminal and see if ONOS has received the new route.

Code Block
onos> routes

   Network            Next Hop
   192.168.1.0/24, nexthop=     10.0.1.1

   192.168.4.0/24, nexthop=     10.0.4.1       
Total SDN-IP routes = 4

We see the new route to 192.168.4.0/24 has appeared in the list. Also, when SDN-IP received the route it installed a new MultiPointToSinglePoint intent into the network.
