Hello,

I'm referring to the "IE R&S Dynamips Hardware Specification" file and see inconsistencies between the Dynamips WAN Cabling Diagram in Page 2 and corresponding Dynamips Interface Connections Sheet in Page 4.

Have listed a couple of them. Appreciate if you could let me know if I'm doing something wrong here.

Connections Sheet shows R1 S1/0 connected to R2 S0/0 and R2 S1/0 connected to R1 S0/0. However the diagram does not show S0/0 on R1 and R2. Also the local DLCI for this connection from R2 S1/0 to R1 S0/0 shows as 202 which I believe should be 201 right which is the remote DLCI listed for reverse direction from R1 to R2.

There are other similar connections listed in the sheet that are not seen in the diagram. Is my understanding correct?

Thanks for your time!

Hi Brian,

Thanks for replying. If I do what you said...all I see is R1, R2, R3, R4 and R5 are connected to each other on s1/0 respectively. However, the interface connections sheet displaying FR Switch Configuration shows up many s0/0 interfaces. I believe this is an error and needs to be corrected. Kindly confirm!

The 'sh cdp neighbor detail' does not throw up any PVC information. I'm able to see the PVC info using 'sh frame-relay pvc'.

Pardon my ignorance but I do not know what you're getting to. I still do not understand why the Dynamips Hardware Specification sheet displays S0/0 for many remote interfaces in the FR Switch Config under Dynamips Interface Connections (Page 4) when they're infact all S1/0 that is reflected in the diagram (Page 2) as well as post configuration of FR on these routers.

Kartik,

There appears to be no r1 s0/0 in the .net file or in the Diagram.  I believe this was/is a remnant of the topologies when there were only RackRentals and some R1s only have a S1/0 whereas some other R1s only have a S0/0.  The way those DLCI mappings were done, they would work regardless of whether the respective rack has R1 with S1/0 or S0/0.  That is my only guess at that b/c it appears to be redundant mappings that would catch those differences between different racks you may rent.

There might be some issues with the diagrams, but you have to kind of create your own revised diagram from what you see in the .net file and perhaps modify your Initial_Configs accordingly.  When in doubt, follow the topology dictated by the .net files and revise your diagram accordingly.

Here are my findings:

1. The DynaMIPS WAN Cabling diagram checks out as accurate.
   
2. The Frame Relay Switch Configuration sheet looks just like the IE R&S Vol II 4.1 Document. 
   It's easy enough to create your own FRSW mapping using the .net file's specifications.
   
3. The DynaMIPS LAN Cabling diagram checks out as accurate as well.
