[f-nsp] VLL & multiple vll-peer question

[Clement Cavadore]

Hi all,

I have plenty VLLs on my network, in a NSP context, where I have "end
user sites" connected to third party telcos (one vlan per end-user). 
The end-users are the 3rd party telcos customers, not mine.

I am trying to understand how could I secure the VLL termination on NSP
side, and be able to have two connections with the 3rd party telco.

For example, I'd like to have the following setup for a VLL:
PE1 --> PE6,PE12 ... where PE1 is the end-user PE, and PE6 & PE12 are
the 3rd party telco interconnection point with my network. 
I am using the following setup within my VLLs, on PE1, under MPLS
context:
----
 vll TELCO.ENDUSER vllid
  vll-peer IP-PE6 IP-PE12
  untag e x/y
----

It is working, but... The question is: How could I choose which PE
between 6 & 12 is the one in use in normal situation ? 
I have noticed that the lowest IP between both of the PE is in use, but
I have no clue on how to force one to be the main, and another one to be
backup. Changing the order of the PE IPs on the vll-peer line does not
influence anything. Is there any way to do it ?

Thanks,
