Open Shortest Path First (OSPF) is link-state protocol that uses the Djikstra Algorithm to determine a shortest path tree.  The OSPF algorithm uses cost defined on links to determine the best path to a network.  For OSPF to remain loop free, each and every router needs to know of all ... Read More

Virtual Router Redundancy Protocol (VRRP)  allows for a group or routers to appear as a single default gateway to end devices.  All the routers must have interfaces that belong in the same subnet.   The end devices point their default gateways to a Virtual Router IP (VIP) address. VRRP is an open ... Read More

Virtual Router Redundancy Protocol provides end devices alternate default gateways without having to be configured for them. With VRRP, a end device continues to speak to the same MAC Address discovered during ARP resolution, because of the Virtual IP (VIP) configuration in VRRP. Configuring VRRP requires knowledge of the Layer 2 ... Read More

We have three HP Comware switches in a triangle with each device being at default configuration after enabling Multi-Instance Spanning Tree (MSTP). We’ll be optimizing the network by adding load-balancing for MSTP and across 20 vlans and link aggregation. A quick overview of the Layer 2 configuration of the network [5800A]display lldp ...
