Re: BGP Multihoming!

Can't you prepend the as path and tell BGP to send the traffic back via one specified route?

Are the AS path equal length and/or same?

Hello Expert,

Needed a help regarding BGP multi homing case.
It seems simple at a glance yet somewhat confusing while explanation

----------------------------------------------
I have 2 BGP multi homing scenarios....

Case1:

ISP A BGP 200 -----> Customer A "router 1" BGP 100
ISP B BGP 300 -----> Customer A "router 2" BGP 100

Case2:

ISP A BGP 200 -----> Customer A "router 1" BGP 100
ISP B BGP 300 -----> Customer A "router 1" BGP 100 (Same router 2
interfaces)
------------------------------------------------------------
I want that my outgoing "traffic" should be from router A(which we can
controll by local preference in case 1 or weight in case 2)
but only ISP B should sent traffice for our AS 100.

How can we achieve that?

Regards,
Manoj P.
