7600: local switching of packets between interfaces and EoMPLS

[petrowic]

Hello, my name is Petr Akimov employed as engineer by ZAO KORTEK - Russia, Moscow. I had success configuring EoMPLS in the following method (VLAN mode):

7600-1 (equipped with WS-SUP720-3BXL and WS-X6724-SFP):

interface Loopback0

ip address 10.14.40.2 255.255.255.255

interface GigabitEthernet6/2.998

encapsulation dot1Q 998

tag-switching ip

mpls l2transport route 10.14.40.3 66

interface GigabitEthernet6/1

description mpls1

mtu 9216

ip address 10.14.54.249 255.255.255.252

ip ospf network point-to-point

tag-switching ip

7600-2(equipped with WS-SUP720-3BXL and WS-X6724-SFP):

interface Loopback0

ip address 10.14.40.3 255.255.255.255

interface GigabitEthernet6/2.998

encapsulation dot1Q 998

tag-switching ip

mpls l2transport route 10.14.40.2 66

interface GigabitEthernet6/1

description mpls1

mtu 9216

ip address 10.14.54.250 255.255.255.252

ip ospf network point-to-point

tag-switching ip

network topology is:

3550-1----7600-1----7600-2---3550-3

|

|

3550-2

There is a problem:

In this network topology I have not found the way to combine EoMPLS as aforesaid and the transparent local switching of packets between the same interface. Is it possible to switch between 3550-1 and 3550-2 through 7600-1?

Best regards,

Petr Akimov

"EoMPLS based on PFC3BXL does not perform any layer-2 look up to determine if the destination MAC address resides on the local or remote segment and does not perform any layer-2 address learning (as traditional LAN bridging does). This functionality (local switching or hair pinning) is available only when using OSM/FlexWAN-based modules as uplinks."

Dear experts, is there any workaround? OSM/FlexWAN-based modules are too expensive!
