Floating Static Route

This topic is to discuss the following lesson:

Hi,
I have question here if I’m ISP With two PE going to customer and need static route from PE to customer and need both PE active how can i deploy it

Hello Mohammed

It really depends on the topology at the edge of the customer’s network, and the direction of the traffic. For traffic originating from the customer, there must be a mechanism with which there will be load balancing between the two PE routers. This can be either a redundant gateway protocol like HSRP or VRRP, using equal or unequal cost load balancing from an IGP, or by using BGP on the edge.

For traffic originating on the Internet and coming into the customer’s premises, static routes on the PE routers won’t be able to provide load balancing across both routers. Here you will need to deploy one of the multi homed BGP scenarios described in the following lesson.

I hope this has been helpful!
