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.
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.

EIGRP
RIP - Only for small networks or those with underpowered hardware that either don't support or don't have the resources for a better routing protocol. IGRP - Basically outdated and supplanted by EIGRP. Again, useful if you can not use EIGRP due to router limitations. EIGRP - Useful in Cisco-only networks of basically any size. EIGRP is an extremely robust and efficient protocol that suits nearly any need other than inter-organization routing. OSPF - Useful everywhere. It's standardized, so it's not limited to a particular vendor. Most appropriate in large multi-vendor networks. It has a higher CPU load than EIGRP does, and it requires more granular control from an administration perspective.

The Video section of the Cisco official website offers a range of videos concerning things like midsize business solutions and Cisco opening up EIGRP.
The acronym EIGRP stands for Enhanced Internet Gateway Routing Protocol. The protocol is loosely based on the Interior Gateway Routing Protocol invented by Cisco.

IGRP - Interior Gateway Routing Protocol EIGRP- Enhanced Interior Gateway Routing Protocol
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
EIGRP (Enhanced IGRP) has replaced IGRP. With the way EIGRP is set up as a protocol it is possible to implement a newer router that only supports EIGRP into a network that is running IGRP. Honestly network admins should be pushing for EIGRP if they are still on IGRP as for many features and advantages EIGRP has over IGRP. Directly from Cisco.com: "Enhanced IGRP provides compatibility and seamless interoperation with IGRP routers. An automatic-redistribution mechanism allows IGRP routes to be imported into Enhanced IGRP, and vice versa, so it is possible to add Enhanced IGRP gradually into an existing IGRP network."

An autonomous system is a group of networks under the same management domain using an interior gateway protocol such as OSPF.
