Routing protocol
A routing protocol specifies how routers communicate with each other to distribute information that enables them to select routes between nodes on a computer network.

Routing
Process of selecting a path for traffic in a network or between or across multiple networks.
Routing tables may be specified by an administrator, learned by observing network traffic or built with the assistance of routing protocols.
Scalability
Property of a system to handle a growing amount of work by adding resources to the system.
A routing protocol is considered scalable with respect to network size, if the size of the necessary routing table on each node grows as O(log N), where N is the number of nodes in the network. Some early peer-to-peer (P2P) implementations of Gnutella had scaling issues. Each node query flooded its requests to all nodes. The demand on each peer increased in proportion to the total number of peers, quickly overrunning their capacity. Other P2P systems like BitTorrent scale well because the demand on each peer is independent of the number of peers. Nothing is centralized, so the system can expand indefinitely without any resources other than the peers themselves.
Open Shortest Path First
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks.
IS-IS
Intermediate System to Intermediate System (IS-IS, also written ISIS) is a routing protocol designed to move information efficiently within a computer network, a group of physically connected computers or similar devices.
Link-state routing protocol
Link-state routing protocols are one of the two main classes of routing protocols used in packet switching networks for computer communications, the other being distance-vector routing protocols.
Internet Protocol
Network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries.
Routers communicate with one another via specially designed routing protocols, either interior gateway protocols or exterior gateway protocols, as needed for the topology of the network.
Routing Information Protocol
One of the oldest distance-vector routing protocols which employs the hop count as a routing metric.
In most networking environments, RIP is not the preferred choice of routing protocol, as its time to converge and scalability are poor compared to EIGRP, OSPF, or IS-IS.
Router (computing)
Networking device that forwards data packets between computer networks.
When multiple routers are used in interconnected networks, the routers can exchange information about destination addresses using a routing protocol.
Interior gateway protocol
An interior gateway protocol (IGP) is a type of routing protocol used for exchanging routing table information between gateways (commonly routers) within an autonomous system (for example, a system of corporate local area networks).
IPv6
Most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.
Dual-stack clients should only be configured to prefer IPv6, if the network is able to forward IPv6 packets using the IPv6 versions of routing protocols.
