Scenario 1: Frame Relay on Multipoint and Point-to-point Subinterfaces.
by David Sudjiman ~ May 5th, 2006. Filed under: Cisco.During my study, I hope I can be consistent enough to create scenarios to work on my Cisco lab. This is one of my scenario for any of you to learn. Configuration and probably some description will be posted (hopefully) the next day. Have Fun!
Scenario.
As shown above, we have two types of network for this cloud FR. RT1, RT2, and RT3 belongs to one multipoint FR network and RT1 and RT4 belong to one point-to-point FR network. Each PVC uses different DLCI number.
| Sending Router | DLCI When the Frame Is Sent | Receiving Router | DLCI When the Frame Is Received | Subinterface type | IP Address |
| RT1 | 122 | RT2 | 221 | Multipoint | 10.1.1.1/24 |
| RT1 | 123 | RT2 | 321 | Multipoint | 10.1.1.1/24 |
| RT1 | 124 | RT2 | 421 | Point-to-point | 10.2.2.1/30 |
| RT2 | 221 | RT1 | 122 | Multipoint | 10.1.1.2/24 |
| RT2 | 223 | RT3 | 322 | Multipoint | 10.1.1.2/24 |
| RT3 | 321 | RT1 | 123 | Multipoint | 10.1.1.3/24 |
| RT3 | 322 | RT2 | 223 | Multipoint | 10.1.1.3/24 |
| RT1 | 122 | RT2 | 221 | Multipoint | 10.1.1.1/24 |
| RT4 | 421 | RT1 | 124 | Point-to-point | 10.2.2.2/30 |
Task. Configure those routers so you will be able to ping from any router to any router. You can use any routing protocol if necessary.
Feel free to have a look my tutorial Configuring Cisco Router 2522 as Frame Relay Switch that comes with more explanation to create the frame relay cloud.
