What is IP source routing?
Source routing is a feature of the IP protocol which allows the sender of a packet to specify which route the packet should take on the way to its destination (and on the way back).
Source routing was originally designed to be used when a host did not have proper default routes in its routing table..
Is BGP distance vector?
“Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information between autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol.”
How do I disable IP source routing?
Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “MSS: (DisableIPSourceRouting) IP source routing protection level (protects against packet spoofing)” to “Highest protection, source routing is completely disabled”.
What is destination based routing?
flow-based routing. There are two flows with the same destination. (a) In destination-based routing, both flows share the same path segment from the first common intermediate hop to the destination; (b) flow-based routing allows a better flow distribution in the network.
What are the two types of routing?
There are 3 types of routing:Static routing – Static routing is a process in which we have to manually add routes in routing table.Default Routing – This is the method where the router is configured to send all packets towards a single router (next hop). … Dynamic Routing –
What is meant by routing algorithm?
Prerequisite – Fixed and Flooding Routing algorithms. Routing is process of establishing the routes that data packets must follow to reach the destination. In this process, a routing table table is created which contains information regarding routes which data packets follow.
What is hop count in routing?
HOP counts refer to the number of devices, usually routers, that a piece of data travels through. Each time that a packet of data moves from one router (or device) to another — say from the router of your home network to the one just outside your county line — that is considered one HOP.
How do you use source routing?
To use source routing, a device must use the API mode, and it must send periodic many-to-one route request broadcasts (AR command) to create a many-to-one route to it on all devices. When remote devices send RF data using a many-to-one route, they first send a route record transmission.
What is record route?
The record route option provides a means to record the route of an internet datagram. … If it is, it inserts its own internet address as known in the environment into which this datagram is being forwarded into the recorded route beginning at the byte indicated by the pointer, and increments the pointer by four.
How does distance vector routing work?
A distance-vector routing protocol in data networks determines the best route for data packets based on distance. Distance-vector routing protocols measure the distance by the number of routers a packet has to pass, one router counts as one hop.
What is strict source routing?
Strict Source Routing allows an originating system to list the specific routers that a datagram must visit on the way to its destination. … In order to facilitate this process, the Strict Source Route option uses an 8-bit pointer field that is placed at the beginning of the option-data field.
Why is distance vector routing not used across the Internet?
On the downside, distance vector protocols do not scale well because they require higher CPU and bandwidth utilization. They also take longer to converge than do link state protocols. Distance vector routing protocols use a hop count to determine the best path through an internetwork.
