Networking requirement

This example describes how the administrator uses the MBGP attributes to
manage route selection.

All routers are configured with MBGP. The IGP in AS200 uses OSPF. Router A in
AS100 is the MBGP neighbor of Router B and C in AS200. Router B and C run
IBGP with Router D which is also in AS200.
