NO, BGP works between ASs, while IGP works inside AS

What routing protocol would be appropriate to use for exchanging routes between ISPs?

BGP


What is the purpose of bgp?

The Border Gateway Protocol (BGP) is the core routing protocol of the Internet. It maintains a table of IP networks or 'prefixes' which designate network reachability among autonomous systems (AS). It is described as a path vector protocol. BGP does not use traditional IGP metrics, but makes routing decisions based on path, network policies and/or rulesets. BGP was created to replace the EGP routing protocol to allow fully decentralized routing in order to allow the removal of the NSFNet Internet backbone network. This allowed the Internet to become a truly decentralized system. Since 1994, version four of the protocol has been in use on the Internet. All previous versions are now obsolete. The major enhancement in version 4 was support of Classless Inter-Domain Routing and use of route aggregation to decrease the size of routing tables. Since January 2006, version 4 is codified in RFC 4271, which went through well over 20 drafts based on the earlierRFC 1771 version 4. The RFC 4271 version corrected a number of errors, clarified ambiguities, and also brought the RFC much closer to industry practices. Most Internet users do not use BGP directly. However, since most Internet service providers must use BGP to establish routing between one another (especially if they aremultihomed), it is one of the most important protocols of the Internet. Compare this withSignalling System 7 (SS7), which is the inter-provider core call setup protocol on thePSTN. Very large private IP networks use BGP internally, however. An example would be the joining of a number of large Open Shortest Path First (OSPF) networks where OSPF by itself would not scale to size. Another reason to use BGP is multihoming a network for better redundancy either to multiple access points of a single ISP (RFC 1998) or to multiple ISPs.


When might you implement BGP on your company network and share routes with Internet routers?

If the network is connected to the Internet using multiple ISP's Very large networks can use BGP internally, but typically only share routes on the Internet if the AS has two (or more) connections to the Internet thought different ISP's

What layer protocol does RIP use?

RIP is a IGP protocol that allows routers to advertise what they know about their routes to other routers. Since routers operate at the network layer (3), so does RIP.


Which protocol used for routing?

A routing protocol is a protocol that routers use to tell each other about available routes. Some of the routing protocols include RIP, EIGRP, OSPF, IS-IS, BGP.
