When designing the IP routing for the Enterprise Campus network， which of these following twoiBGB considerations should be taken into account？（）

• A、 iBGB dual horning with different iSPs puts the Enterprise at the risk of becoming a transitnetwork
• B、 iBGP requires a full mesh of eBGP peers
• C、 Routers will not advertise iBGP learned routers to other iBGP peers.
• D、 The use of route reflections or Confederation eliminate any full mesh requirement while helpingto scale iBGP
• E、 iGBP peers do not add any information to the AS path
