What passes periodic copies of routing tables from router to router?
Distance vector
What a router can do?
A router can do lots of things. One of its main purposes is to (a) maintain routing tables, and (b) resend IP packets it receives, according to these routing tables. In other words, it takes decisions where to send the IP packets. Therefore, it is routers that make the Internet (or smaller groups of interconnected networks, as in a medium-sized or large company) work.
What 2 tasks do dynamic routing protocols perform?
Network discoveryUpdate and maintain routing tables
What is the advantage of dynamic routing?
The router needs a routing table, to know where to send IP packets. The purpose of dynamic routing is to update the routing tables automatically. This means you need much less configuration, and the network dynamically adjusts to topology changes (for example, a router is added, or a cable has a bad connection).
What is RIP in a network?
rip is short for routing information protcol it is a routing protocol that shared routing tables from 1 router to another to a maximum of 16 hops of 16 routers
Explain in detail hierarchical routing in computer network?
It is used for routing the packets hierarchically and it is designed for the following Reasons: 1)Routers need more memory space to store the routing tables. 2)More CPU time needed to scan table. 3)More Bandwidth required to send the scanned report. So this routing algorithm divides the router into number of routers called regions and maintain tables for them to decrease the size. this is done in TELEPHONE SYSTEM.
What is rip protocol?
RIP is a protocol used by routers to exchange information about their routing tables. In dynamic routing, a router learns from other routers about possible routes by advertising what they know. RIP is a protocol that can do that.
What info can you gather from issuing commands on a router or switch?
You can get information about ports, settings on each port, routing tables, filtering rules etc.
What is is a default gateway address?
A gateway is a node (a router) on a computer network that serves as an access point to another network.A Default Gateway is the node on the computer network that is chosen when the IP address does not belong to any other entities in the Routing Table. In homes, the gateway is usually the ISP-provided device that connects the user to the internet, such as a DSL or cable modem. In enterprises, however, the gateway is the node that routes the traffic from a workstation to another network segment. The default gateway is commonly used to be the node connecting the internal networks and the outside network (Internet). In such a situation, the gateway node could act as a proxy server and a firewall. The gateway is also associated with both a router, which uses headers and forwarding tables to determine where packets are sent, and a switch, which provides the actual path for the packet in and out of the gateway. In other words, it is an entry point and an exit point in a network.
Why is a large busy network more likely to use DHCP?
Because static routing requires someone to manual create a routing table for every subnet on the large network and the larger the network the bigger the margin of error in the routing tables larger network also change more, more subnets are added ip are changes every time a router IP is changed or a new router is added a routing table need to be added to that router and the routing tables on other routers need to be modified so the other router know how to communicate with the new router whereas dynamic routing learns the routes for its self saving human error and manpower
When routing tables adapt to network changes the routing system is called?
When routing tables adapt to network changes the routing system is called adaptive.
