Which of the following statements is true of loop detection in BGP. - The underlying algorithm used (a modification of Bellman-Ford) guarantees a loop-free solution. - Because BGP uses policies that might not select the shortest path, loops must be identified and pruned during path selection. To fix this routers will scan the AS_PATH looking for their own AS, and reject any routes that include themselves. - BGP does not guarantee loop-free routing, which is why the TTL/HopCount field must be included in the IP header.

Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.
