A routing protocol specifies how routers communicate with each other to distribute information that enables them to select paths between nodes on a computer network. Routers perform the traffic directing functions on the Internet; data packets are forwarded through the networks of the internet from router to router until they reach their ...
Using hello messages, each node discovers two-hop neighbor information and elects a set of multipoint relays (MPRs). MPRs make OLSR distinct from other link-state routing protocols. Individual nodes use the topology information to compute next-hop paths regarding all nodes in the network using shortest-hop forwarding paths.
The cost of an intra-area path between the two routers is added to the link. Virtual link over tunneling (like GRE and WireGuard): Since OSPF does not support virtual links for areas other than the backbone, a workaround is to use of tunneling. [6] If the same IP or router ID is used, the link creates two equal-cost routes to the destination. [7]
If there are multiple routes with the same subnet mask, the route with the lowest metric is used. If there are multiple default routes, the metric is also used to determine which to use. If there are multiple routes with the same subnet mask and metric, the system may use equal-cost multi-path routing as a forwarding strategy.
Netgear routers commonly offer a choice of two implementations of RIPv2; [19] these are labelled RIP_2M and RIP_2B. RIP_2M is the standard RIPv2 implementation using multicasting - which requires all routers on the network to support RIPv2 and multicasting, whereas RIP_2B sends RIPv2 packets using subnet broadcasting - making it more compatible ...
Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet.

To implement the multicast routing, Internet Group Management Protocol (IGMP) and a multicast routing protocol (Reverse-path forwarding, PIM-SM) for registration subscriber grouping and control traffic are required for multicast transmission. [2] [3] [4] Regarding IP multicast, it is a technique for one-to-many communication over an IP network ...
