Design Scenario's of OSPF & BGP

Question

Accepted Answer

OSPF and BGP are routing protocols used in computer networks.

OSPF (Open Shortest Path First) is an interior gateway protocol used to determine the best path for routing within an autonomous system.
BGP (Border Gateway Protocol) is an exterior gateway protocol used to exchange routing information between different autonomous systems.
OSPF operates within a single autonomous system and uses link-state routing algorithm.
BGP operates between autonomous systems and uses path-vector routing algorithm.
OSPF uses cost as the metric to determine the best path, while BGP uses attributes like AS path, next hop, and local preference.
OSPF is typically used within an organization's internal network, while BGP is used for interconnecting different organizations or ISPs.
OSPF forms neighbor relationships with directly connected routers and exchanges link-state information to build a topology database.
BGP forms peer relationships with other BGP routers and exchanges routing information to build a routing table.
OSPF supports multiple areas to scale large networks, while BGP supports route reflectors and confederations for scalability.
OSPF uses multicast for communication within the OSPF domain, while BGP uses TCP for communication between BGP peers.
