Tell me about routing protocol

Question

Accepted Answer

Routing protocols are used to exchange routing information between routers to determine the best path for data transmission.

Routing protocols are used to facilitate communication between routers in a network.
They determine the best path for data transmission based on various metrics such as hop count, bandwidth, and delay.
Examples of routing protocols include OSPF, BGP, and EIGRP.
Routing protocols can be classified as either distance-vector or link-state protocols.
Distance-vector protocols use hop count as the metric for determining the best path, while link-state protocols consider multiple factors.
Routing protocols can also be classified as interior gateway protocols (IGPs) or exterior gateway protocols (EGPs).
IGPs are used within a single autonomous system (AS), while EGPs are used to connect different ASes.
Routing protocols can be configured to use different algorithms for determining the best path, such as Dijkstra's algorithm or the Bellman-Ford algorithm.
