Is Multi-Vendor EIGRP possible? Linux FRRouting and Cisco IOS demo using GNS3.

Can you run EIGRP between Cisco routers and other vendor devices? In this demo I show you how can with FRRouting (FRR) and Cisco IOSv.

DUAL: The Diffusing Update ALgorithm, a Bellman-Ford based routing algorithm used by EIGRP. EIGRP: Routing Information Protocol is widely deployed interior gateway routing protocol. EIGRP was developed in the 1990’s. EIGRP is a distance-vector protocol and is based on the DUAL algorithms. As a distance-vector protocol, the EIGRP router send updates to its neighbors as networks change, thus allowing the convergence to a known topology. eigrpd supports EIGRP as described in RFC7868

Q. Why is Cisco opening up Enhanced Interior Gateway Routing Protocol (EIGRP)? A. Cisco is opening up its EIGRP routing protocol as an open standard in order to help companies operate in a multi-vendor environment. Customers should be able to pick the best protocol that works for them, based on technical merits. Any networking vendor can now freely implement EIGRP on their equipment, and interoperate with thousands of networks running EIGRP today. Q. What is Cisco releasing? A. Cisco is releasing the basic EIGRP to the IETF as an Informational RFC. This includes all the information needed to implement EIGRP, and its associated features, including High Availability (HA). Q. Will EIGRP specifications change after it's released, just like CDP evolved to LLDP? A. EIGRP is being released as an "Informational RFC", and that allows Cisco to retain control of the EIGRP protocol in order to preserve the customer experience and deployment investments. The EIGRP protocol will not be changed. Q. How does this help with my company transitioning to IPv6? A. EIGRP protocol is very flexible and it supports both IPv4 and IPv6, unlike OSPF where IPv6 is only supported in OSPFv3. If the customer is already running EIGRP for their IPv4 network, they can use their existing knowledge and investment in EIGRP to support IPv6 as well. A lot of companies look to USGv6 for IPv6 migration recommendations and best practices, and now with EIGRP open, Cisco will work with NIST to insert EIGRP as a routing protocol in addition to other Interior Gateway Protocols (IGPs). Q. Who are the vendors planning to implement EIGRP? A. Cisco expects other major networking vendors to come out with their own EIGRP imp ... https://www.youtube.com/watch?v=pmwM3XjAw8s
