What is transit area in ospf?
Transit Area: area through which Virtual Links is configured
What is the area of Devils Backbone Wilderness?
The area of Devils Backbone Wilderness is 26.689 square kilometers.
What is ospf throttle?
OSPF LSA throttling helps the dampening of LSA updates in OSPF during times of network instability.
What is the difference between OSPF and IS-IS and which one is preferred?
OSPF requires an area 0, while IS-IS does not. Like OSPF, IS-IS uses areas when designing the network. However, IS-IS does not require and area 0 like OSPF does. Because IS-IS was originally designed for non-IP protocols, it can more easily support IPv6 routing. Preference is relative to the size of the network. OSPF (a network layer protocol) is more often used in medium to large enterprise networks because of it's special tunnelling features. IS-IS is often used in VERY large ISP networks because of its stability features and the fact that it can support more routers.
Two routers need to be configured within a single ospf area which two components need to be configured on both the routers to achieve this?
Two routers need to be configured within a single OSPF area. Which two components need to be configured on both routers to achieve this?
What type of protocol is OSPF?
OSPF is short form of open shortest path first. OSPF is based on linked state routing.
What type of routing protocol is OSPF?
OSPF is short form of open shortest path first. OSPF is based on linked state routing.
What is topology database in ospf?
In OSPF, a topology database is a data structure that each router maintains to store information about the network topology within an OSPF area. It includes details such as the network links, their costs, and the routers connected to those links. This database is used to calculate the best routes for routing packets through the network.
Which is classified as a link-state routing protocol?
There are actually two OSPF and IS-IS
What does the Cisco IOS use to calculate the OSPF cost to a destination network?
OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.
What are the key characteristics of OSPF?
OSPF has the following features:Fast Convergence OSPF can detect and propagate topology changes faster than RIP. Count-to-infinity does not occur with OSPF.Loop-Free Routes OSPF-calculated routes are always loop-free.Scalability With OSPF, an AS can be subdivided into contiguous groups of networks called areas. Routes within areas can be summarized to minimize route table entries. Areas can be configured with a default route summarizing all routes outside the AS or outside the area. As a result, OSPF can scale to large and very large internetworks. In contrast, RIP for IP internetworks cannot be subdivided and no route summarization is done beyond the summarizing for all subnets of a network ID.Subnet Mask Advertised with the Network OSPF was designed to advertise the subnet mask with the network. OSPF supports variable-length subnet masks (VLSM), disjointed subnets, and supernetting.Support for Authentication Information exchanges between OSPF routes can be authenticated.Support for External Routes Routes outside of the OSPF AS are advertised within the AS so that OSPF routers can calculate the least cost route to external networks.
What are required when adding a network to the OSPF routing process configuration?
network address wildcard mask area ID
