CCIE Enterprise

CCIE written and interview test , which include routing and switching topics such as BGP ,  OSPF and Eigrp . It will prepare you for any test or interview in network engineering section . In addition there MPLS fundamentals questions for ISP work industry .The test questions will help to refresh your information  :BGP principles : iBGP and eBGP default behavior BGP internal connectivity BGP external connectivityBGP vpnv4 familymulti protocol  BGP BGP regular expression BGP features :open standard exterior gateway protocol designed for inter AS domain routingdesigned for huge scale inter - network  like internet path vector protocol and more features like :sends updates to manually defined neighbor as unicast what BGP layer protocol , attributes and default administrative distance  for iBGP and eBGP MPLS fundamentals :The MPLS labels are advertised between routers so that they can build a label-to-label mapping.These labels are attached to the IP packets, enabling the routers to forward the traffic by lookingat the label and not the destination IP address. The packets are forwarded by label switchinginstead of by IP switching.MPLS with ISIS , OSPF MPLS protocol LDP : label distribution protocol MPLS reserved labels MPLS labeling LDP tables : lib , lfibcisco express forwarding CEF table : fibL3VPN , L2PVN Virtual router and forwarding VRFDMVPN Multicast :uRPFSparse modedense mode
