Unanswered Question
Apr 12th, 2010


       I have been trying for several days and have downloaded different IOS but to no luck. Can't get this AtoM to work on my Cisco 7206. I am just wondering if someone can tell me which IOS should work Following is my configuration output.

The following works on Cisco 7204 VXR. But not on my Cisco 7206. I am desperate...Please assist.

R-8(config)#int fastEthernet 1/0.123
R-8(config-subif)#encapsulation dot1Q 123

R-8(config)#pseudowire-class ETH
R-8(config-pw-class)#encapsulation ?
  l2tpv3  Use L2TPv3 encapsulation
  mpls    Use MPLS encapsulation
R-8(config-pw-class)#encapsulation mpls
R-8(config-pw-class)#interworking ip
R-8(config)#int fastEthernet 1/0.123
R-8(config-subif)#xconnect 150 ?
  encapsulation  Data encapsulation method
  pw-class       Pseudowire-class to use for encapsulation and protocol

R-8(config-subif)#xconnect 150 pw
R-8(config-subif)#xconnect 150 pw-class ETH  <--- It doesn't take this command and gives me following error.
MPLS encap is not supported on this circuit   <-- This is the Error I get.

If i Read the feature navigator right that release isn't listed as supporting MPLS.

It shows 12.2(24) then jumps to 12.2(26)

I am just wondering whic IOS...should i use. I have downloaded several and tried them..but no luck. ...Any idea ??

The chassies is irreleevant, it's come down to the NPE version and  the IOS code ran on, however full Point-to-point L2VPN internetworing options supported in 12.2SB and ongoing --> 12.2SRx, but your NPE might be your bottleneck.

Hello Mounir,

             This is my Lab environment. I can try c7200-p-mz.122-31.SB17.bin on my Cisco 7206 and see if the command will work on not. I think in other IOS feature which I downloaded earlier on Cisco 7206 also had MPLS on AToM but no luck to get it to work. ...I will go home and download this on the router and see what happens.

Hello Shassan655,

take in account that

releases with a C2700p in the name are for NPE G1 or NPE G2 not for older NPE like NPE 200

sh ver | inc NPE
Cisco 7206VXR (NPE-G2) processor (revision A) with 917504K/65536K bytes of memory.

sh ver | inc image
System image file is "disk2:c7200p-advsecurityk9-mz.124-20.T.bin"

you cannot run a release for NPE-G1 or G2 over an NPE 200

From feature navigator to support EoMPLS on C7200

ADVANCED IP SERVICESc7200-advipservicesk9-mz.122-33.SRE1.bin51264

if you have 512 MB of RAM and 64 MB of flash but you have  128 MB of RAM and 16 MB of flash so no match and probably you cannot increase RAM on an NPE-200.

for NPE-G2:

ADVANCED IP SERVICESc7200p-advipservicesk9-mz.122-33.SRE1.bin1024256


I see you have a C7200-p that is a different matter then what I have reported above

Hope to help

You must never sleep. I missed the p in my troll thru feature navigator. good call.

Forza Roma.
