The Exterior Gateway Protocol (EGP) is a routing protocol used to exchange routing information between two routers in different autonomous systems (AS). EGP is used to connect an AS to the Internet.
EGP uses a hop-by-hop routing model in which each router forwards packets to the next router in the path to the destination AS. EGP uses a distance-vector routing algorithm in which each router maintains a routing table that lists the ASes reachable from that router and the distance (in terms of the number of hops) to each AS.
When a router receives a packet from another AS, it checks its routing table to see if it has a route to the destination AS. If it does, it forwards the packet to the next router in the path. If it does not, it sends an EGP message to its neighbor router in the same AS asking for a route to the destination AS.
The neighbor router checks its routing table and, if it has a route to the destination AS, it sends an EGP message back to the original router with the route information. The original router then updates its routing table and forwards the packet to the next router in the path. If the neighbor router does not have a route to the destination AS, it sends an EGP message to its neighbor router, and so on, until a router with a route to the destination AS is found.
EGP is a deprecated protocol and has been replaced Which of the following is an examples of Exterior Gateway Protocols EGP? The Border Gateway Protocol (BGP) is an example of an Exterior Gateway Protocol (EGP).
What is External Border Gateway Protocol?
The External Border Gateway Protocol (EBGP) is the standard protocol used to exchange routing information between different autonomous systems (AS) on the Internet. EBGP is typically used to connect an organization's internal network with its upstream service provider's network.
EBGP is a distance-vector protocol that uses the Bellman-Ford algorithm to calculate the shortest path to a destination. EBGP routers exchange full routing tables with their neighbors, which enables them to make informed decisions about the best route to a destination.
EBGP sessions are established between neighboring routers over TCP port 179. EBGP routers must be manually configured to peer with each other; there is no mechanism for automatically discovering neighbors.
EBGP is considered a more reliable routing protocol than the Interior Border Gateway Protocol (IBGP), which is typically used to exchange routing information between different parts of the same AS. This is because EBGP routers are typically less likely to experience routing loops, since they are not running the same protocol.
EBGP is also considered more secure than IBGP, since EBGP routers are typically located at the edge of an AS and are less likely to be compromised by an attacker.
Which exterior gateway protocol is used to route Internet traffic? The primary exterior gateway protocol (EGP) used to route Internet traffic is the Border Gateway Protocol (BGP). BGP is a path vector protocol that uses a variety of attributes to determine the best path for routing traffic. BGP is the only EGP currently in use on the Internet. What is the importance of Exterior Gateway Protocol? Exterior Gateway Protocol (EGP) is a routing protocol that is used to exchange routing information between two different networks. EGP is responsible for exchanging routing information between autonomous systems (AS). EGP is used to connect two different networks that are running different routing protocols. EGP is used to exchange routing information between different ASs.
How many exterior gateway protocols are there?
There are three primary exterior gateway protocols (EGPs):
1. Border Gateway Protocol (BGP)
2. Exterior Gateway Protocol (EGP)
3. Interior Gateway Protocol (IGP)
