Timed Floating Route

[moakintola]

Hello all,

Is it possible to have a route that failover to another ISP2/Connection in the aftertoon from the main ISP1 which is regular. So, I have 2 Towers in same location, both having different ISP. Tower2 is residential and often less busy in the afternoon, now, I want to route some internet traffic from Tower1 to Tower2 during this period and return back to normal in the morning. It is working manually, but I want to try it automatically.
Thanks guys.

Likely doable with an EEM script.

Or, maybe PBR using timed based ACLs.

[moakintola]

Yeah... Like to look at this

Really? Got an example? Please

[Joseph W. Doherty]

Do I have a direct example?  Alas, no, but additional Cisco information on timed ACLs and PBR might help you.

Here is an example using EEM and will toggle the AD of the route to tower2 to make it preferred or floating backup based on time.  This assumes you have a default route to tower1  with an AD of 100 and this remains constant.    The "afternoon" policy will make tower2 more preferred AD and morning policy will make tower2 less preferred.

event manager applet afternoon
 event timer cron cron-entry "0 13 * * *"
 action 010 cli command "enable"
 action 020 cli command "config term"
 action 030 cli command "ip route 0.0.0.0 0.0.0.0 <tower2_NH>"
event manager applet morning
 event timer cron cron-entry "0 7 * * *"
 action 010 cli command "enable"
 action 020 cli command "config term"
 action 030 cli command "ip route 0.0.0.0 0.0.0.0 <tower2_NH> 150"

Yes, it's absolutely possible to implement automatic failover routing between two ISPs using a variety of methods such as BGP (Border Gateway Protocol) or utilizing SD-WAN (Software-Defined Wide Area Network) technology. You can configure policies to reroute traffic from Tower1 to Tower2 during specified timeframes, leveraging the difference in traffic patterns between residential and commercial areas. With proper configuration, you can ensure seamless failover without manual intervention, optimizing network resources and ensuring consistent connectivity.
