 Post subject: 7200 Configuration with ATM switch
PostPosted: Sun Jul 11, 2010 5:58 pm 
I am having a hard time getting a lab setup with an ATM switch. From most of the tutorials that have been made they do not work.

I have a simple lab, 2 7200s with an ATM switch:

interface ATM1/0.105 point-to-point
ip address 172.16.51.1 255.255.255.0
pvc 0/105
encapsulation aal5snap

interface ATM1/0.501 point-to-point
ip address 172.16.51.5 255.255.255.0
pvc 0/501
encapsulation aal5snap

# ATM Switch for PVCs
[[ATMSW A1]]
1:0:105 = 2:0:501
2:0:501 = 1:0:105
===========

Router1#do show atm pvc
VCD / Peak Avg/Min Burst
Interface Name VPI VCI Type Encaps SC Kbps Kbps Cells Sts
1/0.105 1 0 105 PVC SNAP UBR 155000 UP


Router2# show atm pvc
VCD / Peak Avg/Min Burst
Interface Name VPI VCI Type Encaps SC Kbps Kbps Cells Sts
1/0.501 1 0 501 PVC SNAP UBR 155000 UP

I have tried several images, I have even tried a back-to-back configuration with no luck.
I have tried GNS 0.7.1 and 0.7.2 with no luck; this is my first time even attempting to setup ATM, so I am sure
it is something I am doing wrong; as explained, I have tried several tutorials and they are just not working. So they
are all wrong (with successful results) or ATM is broken.

Any Ideas?

Thanks

No help I'm afraid - I've been doing a few ATM configs lately on a 7200 (using the E1 IMA card though, not the ATM card) and your config looks OK, although I'm happy to stand corrected.

I configured your setup and got exactly the same results - everything looks OK at layer 2, but there is no layer 3 connectivity.
Code:
R1#show ver
Cisco IOS Software, 7200 Software (C7200-P-M), Version 12.4(10a), RELEASE SOFTWARE (fc2)
<...>
System image file is "tftp://255.255.255.255/unknown"
<...>
1 FastEthernet interface
1 ATM interface
125K bytes of NVRAM.

65536K bytes of ATA PCMCIA card at slot 0 (Sector size 512 bytes).
8192K bytes of Flash internal SIMM (Sector size 256K).
Configuration register is 0x2102

So all I can do is offer moral support - no help, but I'd also like to see an answer

Have a look there -> http://ccie18473.net/dynamips/dynamips. ... c-p2p-snap

I'll also change the interface for ATM switches in GNS3, I noticed a problem with VPI being VCI and vice-versa.

Hope this will help.
