Divert Microsoft Team traffic routing to Secondary link

[Bhardwajp]

Hi Team,

We have 2 INternet connection and we are using it as Active/Standby.

My standby connection is  no in use we are planning to put specific Microsoft teams traffic on the secondary link as we are receiving lot of complaints regarding the voice quality of Microsoft Team.

Can you please help if we can are the traffic for the below subnet and allow them on the firewall will be required to achieve this.

13.107.64.0/18 13.107.64.0 - 13.107.127.255
52.112.0.0/14 52.112.0.0 - 52.115.255.255
52.120.0.0/14 52.120.0.0 - 52.123.255.255
52.238.119.141/32
52.244.160.207/32

Thanks you in advance.

Are both connections on the same firewall or different firewalls ? 

Either way you are going to need to use PBR to send the traffic via the standby link.

Hello
possible you could utilise Policy Base Routing (PBR)

however please note your return traffic could still choose the primary route - can you elaborate on the existing routing process you have in place?

example
ip access-list extended PBR-acl
permit ip any 13.107.64.0 0.3.255.255

route-map PBR-rm
match ip address PBR-acl
set ip next-hop <secondary ip>

int x/x
description lan
ip policy route-map PBR-acl

Hello,

how do you know (for sure) that the ISP/Internet connection currently in use is responsible for the latency ? Is the link saturated ?

You could also try and implement a basic QoS for Teams traffic first.
