This example describes how the administrator uses the MBGP attributes to
manage route selection. All switches are configured with MBGP. The IGP in AS200
uses OSPF. Switch A is AS100 and serves as the MBGP neighbor of Switch B and
Switch C in AS200. Switch B and Switch C run IBGP for Switch D in AS200. Switch
D is also in AS200.
