IGRP

(Interior Gateway Routing Protocol) A proprietary routing protocol from Cisco that was developed in 1988 to overcome the shortcomings of RIP. IGRP takes bandwidth, latency, reliability and current traffic load into consideration. It is typically used within an autonomous system, such as an Internet domain. IGRP was superseded by Enhanced IGRP (EIGRP), which provides enhancements such as the ability to detect a loop in the network.

Over a ten day period, each CPN was brought off of the Army network, and reprogrammed to use EIGRP and brought back online and validated into the Marine network.
Webinar: Advanced Routing Tips and Tricks: Router Path Selection Modification and Optimization with EIGRP and OSPF
The AG is the provider~s routes dynamically via EIGRP (private AS).
Topics include EIGRP and BGP networks, routing between VLANs, virtual private networks, IOS firewalls, LLQ queuing mechanisms, and class-based header compression.
Items being covered in the middle will include all the common routing protocols RIP, EIGRP, OSPF and BGP.
Support for IPv6 on the OSPF (Open Shortest Path First) routing protocol will be added later this year, followed by Cisco's enterprise-oriented EIGRP (Enhanced Interior Gateway Routing Protocol) in 2010.
Like Route Explorer, MPLS WAN Explorer listens passively to routing protocol (BGP, OSPF, EIGRP, IS-IS) exchanges, creating an accurate, real-time, network-wide routing map that reveals clearly how each site is connected to the VPN(s) and whether any given site can talk to any other.
Topics include single-areas OSPF, EIGRP and troubleshooting routing protocols, switching concepts, LAN design and switches, catalyst switch configurations, spanning tree protocol, virtual LANs, and VLAN trunking protocol.
Expanded IP protocol support for security policies: supports additional IP types (IGRE, ESP, AH, EIGRP, OSPF, PIMSM, L2TP), as well as specifies ICMP/IGMP subtypes when creating customized firewall service objects
EIGRP operations implementation, multi-area OSPF operations and integrating IS-IS are covered, as well.
The RIP and IGRP legacy routing protocols are examined as a prelude to discussion of the contemporary routing protocols for large networks: EIGRP and OSPF.
The module currently supports the OSPF routing protocol, with support for the BGP, IS-IS and EIGRP protocols to be added later this year.
