How can i change traffic form one link to other link automatic !!!

I am providing two links to my client, one link has bandwidth 15 Mpbs and other link has 10 Mpbs (through same router but ports are different) via BGP. My client want that if his primary link goes down then his backup link become 25 Mpbs, vice versa.

 

I have studied Cisco event manger, but want to know that there is any other way to do this task. can it be done by route-map ???

 

Many thanks in advance !!!

Hi there's a few ways to do

Hi there's a few ways to do this ,your using BGP so you could set the primary link to have a better local preference than the backup link , you can also use a route-map to specify which subnets to allow all traffic or just some subnets or alter 1 of BGPs other attributes as well , you could send them a less preferred(higher) MED for the backup link

or

you could use ip sla with tracking of specific routes across the primary and the use a route-map to set the ip next-hop if the route becomes unavailable and add the verify-availability on it to make sure the link you move too can definitely send traffic across the backup and reach the new verified route

EEM can be difficult to setup i would avoid it for something like this when there are easier options available

If this helps please mark as correct
