Configuring EIGRP

What is EIGRP and why to use it?Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used to share routes with other routers within the same autonomous system (AS number). Unlike other routing protocols EIGRP was designed by Cisco Systems as a proprietary protocol, available Read more…

Configure a Default Route

What is a default route and why to use them?Default routes are used to direct packets addressed to networks not explicitly listed in the routing table. Default routes are invaluable in topologies where learning all the more specific networks is not desirable, as in case of stub networks, or not Read more…

Configuring GLBP

What is GLBP and why to use it?Gateway Load Balancing Protocol (GLBP) is a Cisco proprietary protocol that attempts to overcome the limitations of existing redundant router protocols such as HSRP and VRRP by adding basic load balancing functionality. ARP requests sent by arp clients will be answered with MAC Read more…

VRF Route Replication

What is VRF route replication and why to use it?Route replication is an easy way to allow routes to replicate between virtual networks and clients who reside in one virtual network can reach prefixes that exist in another virtual network. Route replication is supported for Static, Enhanced Interior Gateway Routing Read more…

Configuring HSRP

What is HSRP and why to use it?Hot Standby Router Protocol (HSRP) is a Cisco proprietary redundancy protocol for establishing a fault-tolerant default gateway.┬áThe protocol establishes a framework between network routers in order to achieve default gateway failover if the primary gateway becomes inaccessible, in close association with a rapid-converging Read more…

Configuring BGP

What is BGP and why to use it?Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. The Border Gateway Protocol makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator Read more…
