I am trying to achieve a redundant routing setup with two routers with the same ASN who do prefix delegation to a lower router.

The setup is the following:

       AS1000 ISP1    ISP2 AS2000

               |           |

               |           |

   AS10000    R1 ======== R2 AS10000

prefix /22     \   iBGP   /  prefix /22

                \        /

                 \      /

                  \    /

                   R3 AS65000

                   /  \

                  /    \

             net A      net B

         prefix /24     prefix /24

Does anybody has experience with this kind of setup?

Regards,

Richard
