What is BGP in Juniper?

Border Gateway Protocol (BGP) is a path-vector protocol that is used to carry routing information between autonomous systems (ASs). To configure BGP, you must create and enable the BGP routing instance in a virtual router by assigning an autonomous system number to the BGP instance, and then enabling the instance.

What is BGP Sharding?

BGP RIB sharding is to split the BGP process across routes. Different routes are hashed into different threads to achieve concurrency. BGP RIB sharding splits a unified BGP RIB into several sub RIBs and each sub RIB handles a subset of BGP routes. Each sub RIB is served by a separate RPD thread to achieve concurrency.

What is show ip route command in Juniper?

access—Displays the best access-server routes (BGP) in the routing table. access-internal—Displays the best access-internal routes in the routing table. bgp—Displays the best BGP routes in the routing table. bgp-tunnel—Displays the best BGP tunnel routes in the routing table.

What is uptime of router?

Network uptime refers to the time when a network is up and running. In contrast, downtime is the time when a network is unavailable. A network’s uptime is typically measured by calculating the ratio of uptime to downtime within a year, then expressing that ratio as a percentage.
