The virtual router redundancy protocol (VRRP) helps nodes recover from the outage of the default router in a transparent manner. VRRP specifies an election protocol that dynamically assigns the ...

Minimising network downtime is an important aspect of business continuity, particularly given that many organisations are now using one network for all voice and data communications. As a consequence, ...

You can provide this by implementing gateway redundancy using Virtual Router Redundancy Protocol (VRRP) or Hot Standby Router Protocol (HSRP).

Two redundancy protocols have recently been standardized by the International Electrotechnical Commission as IEC 62439-3. Both protocols allow systems to overcome any single network failure without ...

David Davis explains how to configure EtherChannel to increase your bandwidth and provide redundancy on a Cisco network. In my previous article on the Virtual Router Redundancy Protocol (VRRP), I ...

Layer three extensions include inter-VLAN routing with packet filtering together with NAT. OSPF and RIP dynamic protocols are also supported. IPv4 router redundancy can be provided through standard ...

However, the robustness, reliability and availability of wireless connections can be increased dramatically by using standards-based redundancy techniques, such as Parallel Redundancy Protocol (PRP).
