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 :(

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
