Default Gateway Limitations: Impact on Connectivity and Performance

Hosts at the access layer of a hierarchical network take advantage of the alternate default gateways. If a gateway (router interface) fails, the hosts configured with that gateway are cut off from outside networks. A method is needed to provide alternate default gateways in switched networks where two or more routers are connected to the […]

How to Configure Spanning-Tree Mode – Rapid PVST+

The default configuration of the spanning-tree protocol (STP) on a Catalyst 2960 Series switch is PVST+. A Catalyst 2960 series switches support PVST+, Rapid PVST+, and MST, but only one version can be active for all VLANs. Rapid PVST+ is the Cisco execution of RSTP supporting RSTP on a per-VLAN basis. We can control the […]

How to Configure Spanning-Tree Bridge ID – Briefly Explained

When configuring a specific switch as a Root Bridge, the bridge ID priority value must be adjusted to be lower than the bridge priority values of all the other switches on the network. There are two different methods for configuring the bridge priority value on a Cisco Catalyst switch. Method 1 To ensure the switch […]

What is Network Redundancy? – Exclusive Explanation

Reliability is the quality of a computer network that consistently performs according to its specifications. It has long been considered one of three related attributes that must be considered when planning a network. Network Redundancy is one of the key factors to maintain network reliability. Multiple physical connections between network devices provide redundant network paths. […]

How to configure Floating Static Route

Static routes are manually configured paths in a router’s routing table, offering precise control over traffic flow. Unlike dynamic routing protocols like EIGRP or OSPF, static routes are ideal for small networks or backup scenarios. Floating static routes enhance this by serving as a backup path with a higher administrative distance (AD), activating only when […]
