Even if this scenario you describe is "working", it is not compliant
with the suggested configuration from the CCO documentation. Please see
the example below taken from:
http://www.cisco.com/univercd/cc/td/doc/product/atm/c8540/12_1/peregrin/
sw_confg/vir_circ.htm#xtocid180322
"... <snip>
The following example shows how to configure the internal cross-connect
PVC on Switch B between interface ATM 3/0/1 (VPI = 0, VCI = 50) and
interface ATM 3/0/2 (VPI = 2, VCI = 100) (see Figure 6-1):
Switch-B(config)# interface atm 3/0/1
Switch-B(config-if)# atm pvc 0 50 interface atm 3/0/2 2 100
The following example shows how to configure the internal cross-connect
PVC on Switch C between interface ATM 0/0/0, VPI = 2, VCI = 100, and
interface ATM 0/0/1, VPI 50, VCI = 255:
Switch-C(config)# interface atm 0/0/0
Switch-C(config-if)# atm pvc 2 100 interface atm 0/0/1 50 255
Each subsequent VC cross-connection and link must be configured until
the VC is terminated to create the entire VCC.
... <snip>"
Remember that you need to configure two interfaces to switch cells from
one to another. Unless you found a solution to switch cells within the
same interface between two routers...
Hope this helps!
Cheers,
