[c-nsp] Redundancy options for Dual Home Devices using EoMPLS or VPLS

[daniel.dib at reaper.nu]

Hi, 

I'm trying to find any design guide, white paper, Cisco live
presentation or other relevant documents that describe different
redundancy scenarios for a network like this:

The design is not final so if you have any pointers on that as well I
would appreciate it. 

The goal is to deliver services such as EoMPLS, VPLS, Layer 3 VPNs and
so on. The layer 3 part is more clear to me than the EoMPLS and VPLS
scenarios. What options are there to provide redundancy? I have read
about ICCP to share state between PEs. Of course there is the option of
providing backup PW. I also think MST-AG and REP-AG could be viable
options but I'm not sure if they work for all services. 

The devices will likely be ASR9001 for PE and ME2600 for Access.
