Traffic shaping of two separate LANs over one PTP circuit

We currently have a colo with company B. They use our main data center as their DR and have a PTP circuit to their main data center. We are setting up equipment at location B and have an agreement to use 100MB of their 250MB PTP circuit to carry the traffic between our data center and location B.

What configuration commands can we implement on their routers to limit our traffic to 100MB of their circuit?

Is there a way to keep our traffic separate? Since it's a PTP circuit, can we have two sub-interfaces on both ends and pass the relevant traffic over each one?

Yes shaping, or again, policing can limit your bandwidth.  Shaping doesn't generally require as much tuning as a policer to obtain desired/expected behavior.

Yes, you can shape/police specific traffic by using specific ACLs.

Hmm, I recall you can apply shaping to subinterfaces, but perhaps only as a parent CBWFQ policy.

Shaping or policing your traffic would be how you might limit your traffic to 100 Mbps.  Or, depending on your topology, running your traffic through a FE port.

Your options for traffic isolation depends on the kind of circuit your p2p is.

We decided to use a site-to

We decided to use a site-to-site VPN between two ASAs to keep the traffic separated. The routers at both ends of the PTP are only used to carry the traffic.

After doing some research into traffic shaping, I think that will probably help with limiting traffic. If I'm not mistaken, you can only apply traffic shaping to an interface, but not sub-interfaces. You can limit specific traffic by creating an ACL and applying it to a policy map. Does that sound correct?
