What Is Redistribute Connected in BGP?
Most of the networks you experience will run only a single protocol such as OSPF or EIGRP. Maybe it is possible you can find the small old network that can still manage RIP and need to transfer to OSFP and EIGRP. In our network, there are multiple routing protocols so we need some ways or methods to exchange information between protocols this process is called redistribution. We have to experience some issues like RIP use hop count, EIGRP utilizes k-values and OSFP is expensive these are not compatible with each other. When we exchange or imports protocol information from one protocol to another protocol it may create a routing loop this is the problem in redistribution.
Redistribution is not limited to routing protocols there are multiple options like:
Broader gateway protocol:
It is an external gateway protocol it’s a device to exchange information and routing in (AS) autonomous systems on the internet. Broader gateway protocol is categorized into path-vector routing protocol decisions about routing are based on the paths, rules set by the network administrator, and policies of the network. Internal BGP (IBGP) is the routing within the (AS) autonomous system while external Broader Gateway Protocol is the protocol on the internet application.
Working:
The neighbors of the Broader Gateway Protocol are known as peers and are confirmed by manual configuration between the routers to make TCP on 179 ports. Every 30 seconds the speaker of Broader Gateway Protocol sends 19-bytes keep-alive messages for the maintenance of the connection. TCP is used by Broader Gateway Protocol (BGP) as a transport protocol.
When BGP operates on the same autonomous system is called internal BGP while if it is operated on a different autonomous system is called external Broader Gateway Protocol. Border or edge routers in which routers on one boundary of autonomous import information to another autonomous system or in general External Broader Gateway protocol are directly connected. While internal BGP is connected via intermediate routers. The major difference between these two peering external and Internal Broader Gateway Protocols is the way in which they received information from one peer.
