1.2.3 Frame Relay

Routing over Frame Relay

1. Topologies 1.1 Full Mesh The simplest Frame Relay topology is the Full Mesh topology, where each router has a dedicated virtual circuit to another router. Unfortunately this design is rarely found in real life because each additional circuit costs. Of course, having so many circuits available makes it easy …

Frame Relay Switching

1. Frame Relay Switching When setting up a Frame Relay DCE device, we need to follow the following steps. 1. Enable Frame Relay Switching 2. Change The interface type 3. Glue the DLCIs together 1.1 Enable Frame Relay Switching The command is ultra simple, but without it the device will …

Multilink Frame Relay

Frame Relay can be used to group multiple physical interfaces in one logical interface, much like an EtherChannel interface available on the Ethernet Switches. It offers load-balancing and higher availability since the link will be up as long as one physical connection is up. In order to do this, bothe …

Frame Relay Encapsulations – IETF vs Cisco

When configuring a Frame Relay interface, the first thing you should do is enable Frame Relay Encapsulation. This is usually a fairly simple task, just use the classic encapsulation frame-relay command and it will work. Actually there are 3 options: The first one is MultiLink Frame Relay but this deals with …

Frame Relay 101 – part 2

If you thought the previous Frame Relay 101 would cover all basic aspects of Frame Relay, you were wrong. Here’s more info on Frame Relay and how it works, and believe me, we are looking just at the tip of the iceberg here 🙂 7. Non-Broadcast. What difference does it make? The omnipresent nowadays …

Frame Relay 101

Frame Relay is a Layer 2 WAN technology that uses the concept of virtual circuits to transport data. The Frame Relay network is packet switched, but packets towards a destination share a common label, so they follow a strict path according to the label, giving the impression of an end-to-end …
