[c-nsp] Nightmare for load balancing of L2VPN traffic on CRS (traffic from ME3600)

[Amos Thong]

Hi Daren,

Noted the thread is a bit outdated however have seen the similar issue in our network started to surface. 
We have the similar setup like yours. With CRS as P and ME3600 as the access PE.  
We have spoke to Cisco on this recently. The response we got was that they were not putting the FAT-PW ( new feature ) on the ME platform anymore due to the hardware limitation.  Instead we are asked to start considering ASR920 which will have FAT PW in its roadmap.  This was really a major disappointment. 

We have talked to another ISP who had provisioned a 10G PW in their edge causing imbalance link on their CRS LACP link too. 
However they have swapped in routers that support FAT-PW at both end of the PW to solve the issue in the P routers. 

It seems FAT-PW is worth having a look. How was your outcome with Cisco ? Please let us know.  Thanks. 

regardsAmos

Hi Adam & Mark,

 

We have opened Cisco TAC case to check, apparently the
FAT-PW feature is not on Cisco ME3600 roadmap for now.

 

Even with FAT-PW solution, it doesn't sounds ideal as it
requires other equipment to change config to overcome the shortcoming of CRS.
Imagine we already have few thousands of PW around the network.

 

We are talking to Cisco on this. Will keep you guys
posted of the outcome.

Cheers !
