ASR1002 MLP Bundle Problems

Hi fols,

 

We got ASR 1002 for use as LNS and move VPDN settings from 7204 to ASR1002... Looks like PPPoE interfaces (customers works pefect) but MLP Bundle cant establish :(

If i try look show interface for two interface in bundle i see like this:

Looks like normal. but in 30-60 sec this crashed... and sure we have not one customers with MLP... i hope we have around 20-30... so should be tonns MLP :)

 

Sure i lose few hours for find solutions but without luck. Nobody have exacly answer to this question.

I got abolutely working configuration from working NAS (7201 and 7204) and move it to ASR... thats what i have with MLP :((((

Can someone try help me investigate in figure our this....

 

I found same thread on ciscoforums where guys tell "need update ios" but someone update it and have same issue, so i hope issue not in IOS version.

Cisco IOS Software, IOS-XE Software (X86_64_LINUX_IOSD-UNIVERSAL-M), Version 15.3(2)S1, RELEASE SOFTWARE (fc1)

IOS XE Version: 03.09.01.S

System image file is "bootflash:/asr1002x-universal.03.09.01.S.153-2.S1.SPA.bin"

 

If you need anything else, like more debug or more info ... just ask me... i will wait there for your questions.

 

Thanks a lot.!

 

/// Update

 

Little bit more debug from bootflash:/tracelogs/cpp_cp_F0-0.log.7749.20150213111013
