Configuring PTSP
You can configure the packet-triggered subscribers and policy control (PTSP) feature on MX Series routers to allow the application of policies to dynamic subscribers that are controlled by a subscriber termination device, such as a B-RAS or GGSN device, connected to an MX Series router. The subscribers are associated by their IPv4 address and dynamic or static policies can be applied. Dynamic policies take precedence over static policies. When you download a new dynamic policy, it takes effect only for new flows. All new flows and TCP connections use the new dynamic policy. Existing flows are not affected by the new policy unless they timeout, after which they are considered a new flow.
To configure PTSP services on the MX Series router:
- Configure the Multiservices DPC.
- Configure the Diameter application to support the download of dynamic PTSP policies from the external policy manager (such as SRC). The PTSP application also provides statistics collection and reporting.
- Configure the static PTSP service rules.
- Configure statistics collection and reporting in a flat
file.
