    When it comes to the pinnacle in terms of Enterprise Switching and Routing certification, there is no other practical exam than the JNCIE-ENT practical exam. This is an exam that has been designed to validate the ability of the network professional to configure, deploy, troubleshoot as well as manage the enterprise switching and routing platforms on Junos OS. In the course of this practical exam, which goes on for about 8 hours, candidates are expected to create an enterprise network infrastructure that consists of multiple routers as well as switching devices. Successful candidates are expected to have performed system configurations on all the devices, configure features and protocols such as OSPF V2, IPV6, BGP, OSPF V3, MSDP, CoS, 802.1x, SSM, etc. The JNCIE-ENT will be valid for two years and recertification will be achieved by clearing the present version on the JNCIP-ENT examination.
