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 connectivity

BGP vpnv4 family

multi protocol  BGP

BGP regular expression

BGP features :

open standard

exterior gateway protocol designed for inter AS domain routing

designed 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 looking

at the label and not the destination IP address. The packets are forwarded by label switching

instead of by IP switching.

MPLS with ISIS , OSPF
