Hi ... we have xconnect problem between our PE-Router when we apply TE on this xconnect. The xconnect is between Cisco 7600 (s72033-advipservicesk9_wan-mz.122-33.SRA3.bin) and Cisco 7206 NPEG2 (c7200p-advipservicesk9-mz.124-11.T3.bin). The problem is xconnect from 7600 to 7206 is up, but xconnect from 7206 to 7600 is down. We have try to test this TE xconnect to different PE, but still got same symptom. There's no problem if we don't apply TE on this xconnect.
The path from TE is:
PE(7606) - P(7606) - PE(7206). The TE path between 7606 to 7206 and 7206 to 7606 is via same physical path.
Cisco-7606:
#sh mpls l2transport vc 896 detail

Appreciate if someone can help.

Please check the TE in the whole path. If possible post the configs.

hi shivlu,
there's no problem with TE path, and already test some TE between my 7606-PE to several 7206-PE, and got some result.
the TE config is like this:

Reza,
This is a bug. You should move to the latest 12.4T, where it should work just fine.

Hi Tehards,
Thks for your info. Is both 7606 & 7206 should upgrade to 12.4T ?
Thks,

Reza,
The issue is on the 7206. You just need to upgrade this router to the latest 12.4T.
