Creating a Route map or ACL for limiting route

TRACY HARTMANN
Beginner
Beginner

Currently we have a subnet setup that is not routed.  All units just talk to each other inside the Vlan and everything is fine.  Now the user needs the vlan routed ONLY to a specific destination that is at another location.  Basically they want

 

 

10.2.2.0 /24 to only talk to 10.50.0.0 /24   However to get that it has to go through our network to get there and back.  Is this possible with a route-map or ACL?

 

 

Thanks

We do not know much about your environment and if we knew more we might be able to give better advice. But based on what little we do know I would suggest that some sort of tunneling solution (GRE, etc) might allow your subnet 10.2.2.0 to communicate with 10.50.0.0 and not anything else.

Hello,

 

what exactly do you mean by:

 

--> However to get that it has to go through our network to get there and back.

 

?

 

What is the traffic flow supposed to look like ?

 

That said, a simple ACL would look like this:

 

access-list 101 permit ip 10.2.2.0 0.0.0.255 10.50.0.0 0.0.0.255

@Richard Burts said correctly we need to know more information about the device model. IOS code running, how is your network. given short information, we can suggest few lines of ACL, which could lead to something else.

 

some cookbook ACL :
