PPPOE GIG SUB-INTEREFACE - 15.2S 7606-S

We have an environment where we terminate our DSL customers over PPPoE on a 7606-S MPLS PE router with RSP720. The PPPoE sessions are terminated on a GIG V2 interface of a SIP-400. Currently the IOS running on the device is c7600rsp72043_rp-ADVIPSERVICESK9-M, Version 12.2(33)SRD. The following is the current configuration used.

bba-group pppoe 7
virtual-template 7

interface GigabitEthernet2/1/3.142647 access
encapsulation dot1Q 14 second-dot1q 2647
pppoe enable group 7

interface Virtual-Template7
ip vrf forwarding TEST
ip address 10.10.10.1 255.255.255.252

In the  above scenario everything works well.

However we had to upgrade the router IOS to    15.2(4)S Advance IPServicesk9 to support 4-byte ASN. After the upgrading we observed certain commands used to terminate PPPoE on the sub-interfaces not available on 15.2(4)S , although  PPPoE on Gig and Ethernet with QinQ support is listed under 15.2S feature set.

Command not available on 15.2S >>>>  pppoe enable group 7

Any suggestion on how to get this working on 15.2S IOS?

PPPOE GIG SUB-INTEREFACE - 15.2S 7606-S

Hello,

As per this document:

http://www.cisco.com/en/US/docs/routers/7600/ios/15S/configuration/guide/ipsuboe.html

Effective with Cisco IOS Release 15.2(4)S, the Broadband (IP and PPPoE sessions) support is deprecated in Cisco 7600 routers.

On IOS 15.2(2)S 'pppoe enable group' is still supported.

Regards,

Michal
