In this recipe, we will configure the already-deployed ESG for routing to the Distributed Logical Router and upstream physical router. We will use the network topology depicted in the introduction to serve as a reference point for the routing design.

We'll use the BGP to route to the DLR. Routing to the upstream physical router is already set, as all packets will use the ESG default gateway IP address. The physical router is expected to have a single summary router to the ESG uplink interface for the network prefix of 172.16.32.0/22.
