Sample Frame-relay Switch configuration

Filed under Frame Relay
I started working through Narbik’s Advanced technologies workbooks today and when I got to the frame-relay section, I had to reconfigure my frame-relay switch. IE uses the FR switch as both BB1 and FRS. Here is my configuration incase anyone needs it.
Internetwork Expert Volume II: Lab 1 Task 2

Task 2 was frame-relay configs and this was a breeze. Then again this is Lab 1 (Level 5) so it can’t be that hard. Throughout this task, I had Narbik’s words yelling in my ears “Don’t use BROADCAST keyword unless its necessary”. So I did the sub-tasks without broadcast keywords. I will move on to Task 3 tomorrow which is related to IGP and then come back to this config and enable broadcast if necessary.

So this weekend is kind of hectic - July 4th and then a friend’s wedding. I covered Frame-Relay in detail and went over the UniverCD looking up all the frame-relay material. As of right now my frame-relay appears pretty solid. I know the different types of configurations and also when not to use certain configurations. As they say, it takes practice so I am hoping to make a second pass through Frame-relay later on. As of right now I will move on to RIPv2 and EIGRP.
Frame-relay Multipoint
In a multipoint frame-relay configuration, two issues must be resolved before an IP address can be reached
- The destination IP address must be in the routing table with a valid next hop
- There must be a frame-relay mapping to that destination Read more
Narbik’s Bootcamp - Day 1
June 23, 2008 by CCIETalk
Filed under Bootcamp, Bridging & Switching, Frame RelayFinally, the day I have been waiting for has arrived. Its 830am and I am sitting here in the class room. Comfort Inn had a nice Breakfast so I am ready to roll. We have 8 people in the class with different levels of experience. One of the guys has attempted the R&S lab 4 times already. Another guy was in the class with Ethan and Keith so we started talking about the whole Network World fiasco. Narbik looks like a teacher, and I mean Old School teacher! No projector, no power point, no computer screen - Just him and white board and he can spit commands out like a router. Guy knows every single option from the back of his head.

Filed under Frame Relay, Narbik WBLab 6 - “Frame-relay end-to-end Keepalive - FREEK” requires us to configure a frame-relay cloud with a hub and spoke topology using point-to-point sub-interfaces. This part was similar to the other frame-relay labs I have done in this workbook. To be honest, I have never configured end-to-end keepalives before so I had no choice but to look through the DOCCD. As always, this was a great exercise that helped me get familiar with the DOCCD
Configuring Frame-relay end-to-end keepalives is documented under Cisco IOS Wide-Area Networking Configuration Guide, Release 12.4. Task 2 asks you to configure end-to-end keepalives using bidirectional mode. Using the command reference listed in the table, use the mode option to configure this. Task 3 requires that we configure request mode on R1 and reply mode on R3. Once again use the mode option to change the modes on the routers. These two tasks were a good starting point for me to understand keepalives. I read through the DOCCD explaination and tried a few other combinations to really master this concept.

Filed under Frame Relay, Narbik WBLab 5 - “Point-to-point, Multipoint and PPP” builds on the earlier labs with the addition of point-to-multipoint links and PPP encapsulation. Setting up point-to-point and multipoint interfaces was a breeze and I was able to do it without looking over the DocCD. However, I struggled to configure CHAP and had to look through the UniverCD to make any sense out of it. To make matters worse, I couldn’t find Virtual Template on the DocCd and had to google a few terms. For your reference, Virtual-Template is located under “Dial Solutions” and now I can get to that without a fuss. Anyhow, once I was able to look up the configuration, it all made sense. Use the following steps to configure PPP for the link: Read more

Filed under Frame Relay, Narbik WBLab 4 - “Full Mesh Frame-relay configuration using Point-to-Point Sub-interfaces” wants us to use point-to-point subinterfaces to create a full mesh network. For this we create a subinterface for each connection and assign the local dlci to that sub-interface using the Frame-relay interface-dlci command. Since the routers are configured as point-to-point links and every link is on a different IP subnet, we won’t be able to ping every IP address in the cloud. We wil either need static routes or a dynamic routing protocol to achieve full connectivity at layer 3.

Filed under Frame Relay, Narbik WBLab 3 - “Configuring Frame-relay point-to-point sub-interfaces” cover the configuration of point-to-point subinterfaces. In this lab I was required to configure a frame-relay hub and spoke network using sub-interfaces. Key thing to note: If routers are configured using point-to-point subinterfaces, they will not generate inverse-arp requests, however, if they receive a request then they will respond to it.

Filed under Frame Relay, Narbik WBLab 2 - “Full Mesh Frame-relay configuration using Frame-relay map statements” is building upon Lab 1 but instead of using a hub-n-spoke topology, we are required to configure a full mesh setup using map statements. Once again very basic but still important for a CCIE candidate. Things like these should be second nature to us when it comes to the Lab so we can spend more time on complex tasks. Another requirement was to turn off inverse-arp so all the DLCIs are learned statically. So far so good, time to start Lab 3.

Filed under Frame Relay, Narbik WBLab 1 - “Hub-n-Spoke using Frame-relay map statements” is straight forward in a way that it goes over the basics of frame-relay and asks you to configure a basic frame-relay cloud using hub and spoke design. It also requires that we turn off the inverse arp before no shutting the interface. Finally I was required to use frame-relay map statements to configure full mesh connectivity between IP addresses. Off to Lab 2!
