Re: Best way to have redundancy announcing on separate routers

Tony,

"The NANOG Mailing List is a community-moderated forum, open to all. Established in 1994 to provide the open exchange 
of technical information, it provides the opportunity for lively discussions of specific implementation challenges that 
require cooperation among network service providers." - NANOG Usage 
Guidelines<https://nanog.org/legal/usage-guidelines/>

I disagree with your remark that "this is not an appropriate channel for this query". I would believe that Jean's query 
falls under the "open exchange of technical information" category.

Regards,
Christopher Hawker

Sorry, this is not a general help list for basic networking skills. There are many options for appropriate training 
available, but this is not an appropriate channel for this query.

Subject: Best way to have redundancy announcing on separate routers



Hi Folks,



I'm trying to achieve total redundancy on a multihomed environment:



ISP 1 <=> Router 1 <= X => Router 2 <=> ISP 2

Where X is my Network.



In the example below, he announces separate blocks to each ISP.

I would like to do a failover model, where if one ISP goes down the other would take over.

Please share your thoughts on this.



Best regards,
