Re: Best way to have redundancy announcing on separate routers

[Mike Hammett <nanog () ics-il net>]

How much capacity and how much network do you have between router 1 and router 2? 


Are the routers between DFZ capable? 
Do the links have the ability to carry the full load? 
How many routers between router 1 and router 2?

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,
