What is the administrative distance value of BGP, and what are the BGP states?

Question

Accepted Answer

BGP (Border Gateway Protocol) is a routing protocol used in internet networks. It provides scalability, redundancy, and policy control.

BGP is used to exchange routing information between different autonomous systems (AS)
It allows for efficient routing decisions based on policies and network conditions
BGP states represent the different stages of establishing and maintaining BGP peering sessions
Examples of BGP states include Idle, Connect, Active, OpenSent, OpenConfirm, Established

Accepted Answer

BGP has two parts.

1> ebgp and ad value is 20,its working on diffrent as no.

2> ibgp and ad value is 200,its work on within same as no.

bgp attributes has two types:-

1> well known 2> optional

Accepted Answer

BGP (Border Gateway Protocol) routers usually receive multiple paths to the same destination. Like how our IGPs (RIP, EIGRP, OSPF) work, we need to select the best path to each destination.

BGP forms a TCP session with neighbor routers called peers. BGP uses the Finite State Machine (FSM) to maintain a table of all BGP peers and their operational status. The BGP session may report in the following states:

Idle

Connect

Active

OpenSent

OpenConfirm

Established
