Work on VRRP started in 1997 with a first draft published by the Internet Engineering Task Force (IETF). In 1998, the protocol was officially defined. [2] VRRP is an open standard, but Cisco claimed that their Hot Standby Router Protocol, a similar but proprietary protocol with essentially the same facility, is patented and licensed. [3]
Its primary purpose is to provide failover redundancy, especially when used with firewalls and routers. In some configurations, CARP can also provide load balancing functionality. CARP provides functionality similar to Virtual Router Redundancy Protocol (VRRP) and to Cisco Systems' Hot Standby Router Protocol (HSRP).

In a typical deployment, customer edge (CE) routers handle local routing in a traditional fashion and disseminate routing information into the provider edge (PE) where the routing tables are virtualized. The PE router then encapsulates the traffic, marks it to identify the VRF instance, and transmits it across the provider backbone network to ...
Examples of such protocols include (in approximate order of creation): Hot Standby Router Protocol (HSRP) - Cisco 's initial, proprietary standard developed in 1998 [ 3 ] Virtual Router Redundancy Protocol (VRRP) - an open (albeit patent-encumbered) standard protocol based largely on Cisco's HSRP
Gateway Load Balancing Protocol (GLBP) is a Cisco proprietary protocol that attempts to overcome the limitations of existing redundant router protocols by adding basic load balancing functionality. In addition to being able to set priorities on different gateway routers, GLBP allows a weighting parameter to be set.
The Vyatta system is intended as a replacement for Cisco IOS 1800 through ASR 1000 [3] series Integrated Services Routers (ISR) and ASA 5500 security appliances, with a strong emphasis on the cost and flexibility inherent in an open source, Linux-based system [4] running on commodity x86 hardware or in VMware ESXi, Microsoft Hyper-V, Citrix ...
Example of setting up EIGRP on a Cisco IOS router for a private network. The 0.0.15.255 wildcard in this example indicates a subnetwork with a maximum of 4094 hosts—it is the bitwise complement of the subnet mask 255.255.240.0.
