AS on-top of another AS

Hi,

Have anyone here tried or have any idea how to run one AS on top of another AS?

I would like to use my current backbone network (AS1)and run another AS (AS2) on the same infra.

example:

physical

========

RA--R1--R2---RB

logical

-------

R1--[AS1]--R2

RA--[AS2]--RB (on top of AS1)

I am thinking of EoMPLS using cat3750. Maybe you guys have any brilliant idea to that I can just use router to do the trick.

Your ideas and help is higly appricated.

Thank..

Re: AS on-top of another AS

Hi Mazlan,

One simple option is to create a GRE tunnel between RA and RB and then run BGP directly between RA and RB using AS2. You will not need to change anything on R1 or R2 at all.

Hope that helps - pls rate the post if it does.
