Cisco AnyConnect with Zscaler app - Routing issue

Hi Team,

 

Need your assistance on the subject.

We have a strange routing issue while connecting Cisco AnyConnect with Zscaler app running alongside

 

> Zscaler app also add routes on the machine. It has its own virtual adapter

> Issue we have is with a specific route 100.64.0.0/16 which gets added by Zscaler app

> When we connect to Cisco AnyConnect, most of the times 100.64.0.0/16 route disappears causing Zscaler app services to fail.

> As soon as we disable Cisco AnyConnect, route comes back. Hence Zscaler app service comes back up

> Cisco AnyConnect is running on version 4.7

> We used a utility NetRouteView. While running this utility, we replicated the issue and saw below

 

            - As soon as we connect Cisco AnyConnect, most of the routes gets wiped and comes back

            - However, most of the times 100.64.0.0/16 does not get added back

 

> We tested on another machine, no such issue. And it had Cisco AnyConnect version 4.4

> On 3rd machine, again no such issue. This one is on same version as of the machine we replicated the issue on i.e. 4.7. However, in this case we do not see Cisco AnyConnect wiping/refreshing the routes

 

In Cisco AnyConnect we do not have any route in excluded list which is overlapping with 100.64.0.0/16

And the issue is happening with multiple users

I am not sure if we can have Cisco not to wipe/refresh the routes, just add the excluded routes.

 

Any feedback will be helpful 

 

Thanks
