Enhanced Interior Gateway Routing Protocol (EIGRP) was once as Cisco Propitiatory routing protocol for Cisco routers. However many routers that are not Cisco now support the use of EIGRP.
Cisco has a few proprietary protocols, though many of them have been standardized, or adapted into emerging standards. The most popular Cisco proprietary protocol that hasn't been adopted as a standard is probably EIGRP. bit.ly/1OMvbZW

RIPv2 and EIGRP
EIGRP is a Cisco proprietary routing protocol and therefore can only be used with Cisco routers.You can do route redistribution on Cisco routers, this allows you to take routes from another routing protocol (such as OSPF or RIP) and place them into the EIGRP network that way downstream nodes can be informed of routes available.

Open standard protocols: Rip or OSPF. They are not Cisco proprietary protocols.
An autonomous system is a group of networks under the same management domain using an interior gateway protocol such as OSPF.

Routing protocols are used by routers (RIP, EIGRP, OSPF) Routed protocols are the actual protocols on the wire (TCP/IP)
EIGRP
Routers work with many different kinds of protocols, for different purposes. They work with layer-3 protocols such as IP and IPX, with routing protocols such as RIP, EIGRP, and OSPF, with VLAN-specific protocols, with DHCP, Telnet, and many others more.Routers work with many different kinds of protocols, for different purposes.

Most modern routing protocols send information about the network mask. In the Cisco Academy, we learn about several protocols that do, and don't, include information about the network mask; those who don't do so, don't allow VLSM (subnets of different sizes).RIP v.1: NoRIP v.2: YesIGRP: No (marked as "obsolete" in the new version of the Cisco curriculum)EIGRP: YesOSPF: YesIS-IS: Yes (I believe so; we don't study this in detail)Most modern routing protocols send information about the network mask.
