Difference between EIGRP and BGP

1. Enhanced Interior Gateway Routing Protocol (EIGRP) :
EIGRP is used to share the information from one router to neighbor routers if they exist in same region. It is also a complex protocol but can be configured and make it work easily in small and large networks. It is also a hybrid protocol because it uses features of both distance vector routing and link-state routing protocol.

2. Border Gateway Protocol (BGP) :
In BGP, Transmission control protocol is used. It is type of mesh topology or design.It works by two independent networks (Autonomous Systems or AS) exchanging routing information. The two routers agree to exchange information about how to reach certain ip-ranges. BGP uses Transmission control protocol (TCP) port 179.

Difference between EIGRP and BGP :

1. EIGRP stands for Enhanced Interior Gateway Routing Protocol. BGP stands for Border Gateway Protocol.
2. It works on Dual distance vector algorithm. It works on Best path algorithm.
3. It is basically use for lager size organization. It is basically use for very lager size organization as compared to EIGRP.
4. It is hybrid type. It is a Vector State type.
5. It is interior gateway protocol. It is external gateway protocol.
6. It is a intelligent routing protocol. It is a more intelligent routing protocol than EIGRP.
7. In EIGRP, Internet protocol is used. In BGP, Transmission control protocol is used.
8. Its administrative distance are 90 (Internal) and 170 (External). Its administrative distance are 20 (Internal) and 200 (External).
