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 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…

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. The 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…

Policy-Based Routing

What is Policy-Based Routing and why to use it?Policy-based routing (PBR) is a technique used to make routing decisions based on policies set by the network administrator. When a router receives a packet it normally decides where to forward it based on the destination address in the packet, which is Read more…

Configuring Static Routes

What are static routes and why to use them?Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from a dynamic routing traffic. In many cases, static routes are manually configured by a network administrator by adding in entries into Read more…

Configuring OSPF

What is OSPF and why to use it?Open Shortest Path First (OSPF) is interior gateway protocol (IGP) that makes use of a link state routing (LSR) algorithm. OSPF supports complex networks with multiple routers and may be structured, or subdivided, into routing areas to simplify administration and optimize traffic and resource Read more…
