[c-nsp] Multihomed PE-CE toplogies

[Novice]

Hi Guys,

We have a large service Provder (a big Cisco shop) who is trying to do
Multihoming of CE to 2 different SP. Wanted to know of any issues and are
there any most commonly recommended Dual homed toplogies which others have
tried.

Are there any good doc referring to issues and known gotchas. Customer is
asking what are the options available ?

Thanks in advance.
