RE: Designing FR for 3 branches [7:16030]
I think you are going down the right track. I always try to have a coalition between my DLCI and my IP. We have a good sized frame network and man does it help do be able to say " Oh, location 1 is DLCI 101 with Wan IP x.x.x.x" This type planning will also help out when you grow and try to track it all. I use /30 on all my wan connections but I also figure out hw many nodes on each locating then provision 10-20% over that depending on the locations potential. Seems to work great for me.

It will not be fully meshed, but a PVC between the main office and each branch office. Since I've come accross much of this during my studies, I would like to show you my draft, and hope that some of you will throw some comments back to me, whether or not it's a good design or a bad design. Our branch offices each have a branch code, and the three branch offices I am connecting has 1, 7 and 8. I have planned on buying a 2610 with a WIC-1DSU-T1= for the main office, and 1720's with WIC-1DSU-T1='s for the branches. The main office will be 768/384 (bw/cir) and the branches 256/128. My LAN at the main office is 10.0.0.0 / 8 (total overkill, but that's how it was, and that has been fine with me so far). If we take branch office 1, the setup I have drafted looks like this: 2610- Ethernet 0: 10.1.1.9 / 8 2610- Serial 0.1: 172.16.1.1 / 30 1720- Serial 0 : 172.16.1.2 / 30 1720- FastEthernet 0: 172.16.1.129 / 25 ### QUESTION 1 ### Would this be the best way of using VLSM for hierarchical design? ## Next, I would like to match the branch office number with as much as possible, so my idea was to skip subinterface 0.2 thru 0.6 on the 2610, so the next branch office setup would look like this: 2610- Ethernet 0: 10.1.1.9 / 8 2610- Serial 0.7: 172.16.7.1 / 30 1720- Serial 0 : 172.16.7.2 / 30 1720- FastEthernet 0: 172.16.7.129 / 25 ### QUESTION 2 ### Would that be a good idea, and if no - then why not? ## At last, I would like to see if I can match the DLCI also, but I think that I recall 16 being the lowest number to use (is that correct?). Therefore, the branch office connections would have DLCI 1, 7 and 8 or 21, 27 and 28 if 16 is the lowest. ### QUESTION 3 ### Is this a good idea, and if no - then why not? ## I appreciate any comments on this, and hope that you can help me learn the "no-so-much-documented" areas of study guides, so I can design this Frame Relay the right way from the beginning.

RE: Designing FR for 3 branches [7:16030]
In my experience with Worldcom , you might have trouble choosing your own DLCI numbers. You are likely to get assigned arbritrary numbers starting at 100+. I have found it helps to assign the subinterface the same as the DLCI number, it really helps in troubleshooting when you do a show frame pvc and you can look at the subif's and know immediately what circuit it is. May not be as helpful when you have 3 circuits, but it helps more as the number of pvc's increase. You can then put the office branch number in as a description. -Patrick On Tue, 14 Aug 2001 12:03:08 -0400, Ole Drews Jensen wrote: > Thanks for your input Steve. > > Have a great day, > > Ole > > > > ~~~ > Ole Drews Jensen > Systems Network Manager > CCNA, MCSE, MCP+I > RWR Enterprises, Inc. > [EMAIL PROTECTED] > ~~~ >http://www.RouterChief.com > ~~~ > NEED A JOB ??? >http://www.oledrews.com/job > ~~~ > > -Original Message- > From: Steve Smith [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, August 14, 2001 10:44 AM > To: Ole Drews Jensen; [EMAIL PROTECTED] > Subject: RE: Designing FR for 3 branches [7:16030] > > > > I think you are going down the right track.
