RE: Redundancy with two ISPs by configuring BGP

If you want redundancy for inbound connection like mail and web, then you
need to get your own IP address block to advertise to each BGP peer or get
each ISP to agree for you to advertise the others IP address space through
them.

Both are difficult and unlikely solutions if you are not a large enterprise.

I seem to recall a product a few years back called Fatpipe that I think
solved this problem.

Subject: Redundancy with two ISPs by configuring BGP

Hi Guys,

   I have two public IPs (two different ISPs) and i am planning to
configure redundancy between these IPs for my network. Here i can configure
HSRP or any redundany protocol but the challenge is for the mail or
webserver where the incoming traffic towards them will face issues as the
public IP will change.

   BGP will be an idea solution, my idea is to configure BGP multi homing
with one set of public IPs from one ISP to be peered with the other ISP
with private AS at our premise. Do let me if this will be an idea solution
or pls suggest any other solutions.

Regards,
Umesh
