Solved: Sub internface shutdown in Frame Relay point to point in GNS3

Wilson Kwok · ‎01-19-2014

Hello

Please take a look on GNS3 file in attached, I'm sure already configured both routers s1/0 is no shut, but still status down, please help.

cadet alain · ‎01-20-2014

Hi,

of course GNS3 supports it(but only on routers which do Frame-relay switching) but these are your 2 DTE devices, no ? so they should be intf-type DTE and the switch where they are connected should be DCE(which is default for built-in GNS3 FR switch.

Hi,

on both serial interfaces :

no frame-relay intf-type nni

Hi cadet alain

This lab is following our real environment, is GNS3 don't support frame-relay intf-type nni ?

Thanks

cadet alain · ‎01-20-2014

Hi,

of course GNS3 supports it(but only on routers which do Frame-relay switching) but these are your 2 DTE devices, no ? so they should be intf-type DTE and the switch where they are connected should be DCE(which is default for built-in GNS3 FR switch.

Sorry, I don't understand, can you tell me how to do that ?

Wilson Kwok · ‎01-20-2014

Completed with frame-relay intf-type dte on both router.

Thanks

Wilson Kwok · ‎01-22-2014

Hi Cadet alain,

Now I want to create sub-interface in s1/0, it allow me to create s1/0.1, but can't create s1/0.2, it showing "Incomplete Command", is it GNS3 bug ?

Thanks

Bilal Nawaz · ‎01-22-2014

Hello,

I think you might need to specify the type of sub interface it is after int s1/0.2 - Now, depending on your topology it could be either options.

Same as what you have done for your first sub-if. Example below of the options...

Rack1R1(config)#int s0/0/0.1

% Incomplete command.

Rack1R1(config)#int s0/0/0.1 ?

multipoint Treat as a multipoint link

point-to-point Treat as a point-to-point link

hth.

Wilson Kwok · ‎01-24-2014

Hi

You right, I forgot use the point to point command.

Now I have another problem, after I created s1/0.2 interface with ip address in both routers, I can ping each others with this subinterface ip address, but s1/0.1 can ping.

Please take a look in attached GNS3 file.

Thanks !

Bilal Nawaz · ‎01-24-2014

Hello, I was able to open the file, I saw R3 and R4 connected to a frame-relay switch, however there were no configs on the routers. Could you please post'em up here?

Have you checked your frame-relay mapping on the frame-relay cloud is correct?

Hi,

interface Serial1/0.2 point-to-point

ip address 172.17.228.21 255.255.255.252

frame-relay interface-dlci 341

!

interface Serial1/0.3 point-to-point

ip address 10.10.228.21 255.255.255.252

frame-relay interface-dlci 441

None of these DLCIs exist on CU and the same for DLCIs 340 and 440 on R4

Also you can get rid of the frame-relay switching command on both routers as they are FR DTE devices so they don't need to switch.

Alain
