OSPF: The Open Shortest Path First (OSPF) protocol is commonly used by network routers to dynamically identify the fastest and shortest available routes for sending packets to their destination. RIP: The Routing Information Protocol (RIP) uses "hop count" to find the shortest path from one netwo...
An ASBR does not necessarily reside on the border of an AS. It can be an internal router or an ABR. An OSPF device that has imported external routing information will become an ASBR. Route Types Inter-area and intra-area routes in an AS describe the AS's network structure. AS external...
4. Open shortest path first (OSPF) protocolOSPF protocols classify as link-state, interior gateway, and classless protocols. They use the shortest path first (SPF) algorithm to ensure the efficient transmission of data. Internally, this type maintains multiple databases with topology tables and info...

OSPF is a link-state routing protocol featuring: Multicastpacket transmission, reducing load on the routers that do not run OSPF Support for Classless Inter-Domain Routing (CIDR) Load balancing among equal-cost routes Packet authentication With the preceding advantages, OSPF is widely accepted and u...
OSPF:The Open Shortest Path First (OSPF) protocol calculates the most efficient network routes based on a variety of factors, including distance and bandwidth. RIP:The Routing Information Protocol (RIP) is an older routing protocol that identifies distances between routers. RIP is an application lay...
Open Shortest Path Firstrouting has replaced RIP as the most widely used interior gateway protocol in the enterprise. This is mainly due to its simplicity and inability to scale to large, complex networks. In contrast, Border Gateway Protocol (BGP) is a path vector routing protocol used to tra...
To enable LFA, use the fast-reroute command, then the area we want to protect, area 0 in our case, next we have to configure the priority, there are two options; high and low. When we use the high priority, OSPF treats loopback and /32 prefixes with higher priority. When we choose...
OSPF is a link-state routing protocol, it runs over IPv4 and IPv6, but does not use a transport protocol. It encapsulates its data directly in IP packets with protocol number 89. This is in contrast to other routing protocols, such as the Routing Information Protocol (RIP) and the Border...
OSPF can be overkill for very small networks. 8 What does BGP stand for? Border Gateway Protocol, used for routing between different networks. 7 Where is OSPF typically used? In single autonomous systems like corporate networks or campuses. 6 What is the primary use of BGP? For internet rout...
