Solved: Frame relay problem

gurkamal01 · ‎06-27-2008

Hi there

i am trying to set up a frame relay hub and spoke enviroment in my home lab.I have three 2600 routers and one frame switch(2520).R1 is the hub

I have the s0/0 of R1 connected to s1 of FR switch.R2 has s0/0 coneected t0 S2 of FRS and R3 has s0/0 to S3 of FRS.

The conf on FRS is

WHEN GO FRS AND RUN

SHOW FRAME ROUTE it gives output

When i Run SHOW FRAME MAP on R1 It gives output

R1#sh frame map

Serial0/0 (down): ip 172.12.123.2 dlci 122(0x7A,0x1CA0), static,

broadcast,

CISCO, status deleted

Serial0/0 (down): ip 172.12.123.3 dlci 123(0x7B,0x1CB0), static,

broadcast,

CISCO, status deleted

THE OUTPUT OF SH FRAME MAP ON R2 IS

R2#sh frame map

Serial0/0.123 (down): ip 172.12.123.1 dlci 221(0xDD,0x34D0), static,

broadcast,

CISCO, status defined, inactive

Serial0/0.123 (down): ip 172.12.123.3 dlci 221(0xDD,0x34D0), static,

CISCO, status defined, inactive

How can i bring this pvc to be active

please help

Hi There

Another person using the Bryant Advantage study material. I recognise the configuration :)

Can I ask if you have run the command "no shutdown" on the Frame interfaces on R1, R2 & R3 as well as on the Frame Switches interfaces?

The "show frame map" command on R1 shows "status deleted" this signifies a problem at the local end, and is usually either a problem with the frame mappings or the interface administratively down. Your frame mappings look correct.

The "show frame map" statements on R2 & R2 show "status defined inactive". This signifies a problem on the far end. You would expect to see this if the far end router was not yet configured for Frame Relay.

So my advice at this stage is check that all interfaces are open, on the Frame switch as well as the hub and spokes. After that I would make sure that you have the DCE ends of you serial back to back cables connected to the Frame Switches interfaces and the DTE ends going to to the hub and spoke routers.

Other than that I am not sure as I have compared your configuration with both my own home lab and the Bryant Advantage study material and it looks ok.

Michael

hi

thank so much michael

I just got to much bad luck whenever i sit down and work on the routers occasionally

My cables ditch me all the time and this is the third time it happenned to me.

it was a faulty cable wasting all my time

Whew!
