VPRN Features

Filter Policies

In Release 3.0 of the 7705 SAR, IP filters are applied to ingress pseudowire SAPs (Epipes
and Ipipes), VPRN SAPs, and IES SAPs, as well as to ingress network interfaces and IES
management SAPs.
Configuration of filter policies is similar for network interfaces, IES management SAPs,
Ethernet and IP pseudowire SAPs, and VPRN and IES SAPs. This guide describes the
assignment of filter policies to SAPs. For information on IP filters assigned to SAPs, see
Filters

CE to PE Routing Protocols

The 7705 SAR VPRN supports static PE to CE routing protocol.

PE to PE Tunneling Mechanisms

The 7705 SAR supports multiple mechanisms to provide transport tunnels for the
forwarding of traffic between PE routers within the RFC 2547bis network.
The 7705 SAR VPRN implementation supports the use of:
These transport tunnel mechanisms provide the flexibility of using dynamically created
LSPs, where the service tunnels are automatically bound (the "auto-bind" feature) and there
is the ability to provide certain VPN services with their own transport tunnels by explicitly
binding SDPs, if desired. When the autobind command is used, all services traverse the
same LSPs and do not allow alternate tunneling mechanisms (like GRE) or the ability to
craft sets of LSPs with bandwidth reservations for specific customers, as is available with
explicit SDPs for the service.

Per-VRF Route Limiting

The 7705 SAR allows setting the maximum number of routes that can be accepted in the
VRF for a VPRN service. There are options to specify a percentage threshold at which to
generate an event that the VRF table is nearly full and an option to disable additional route
learning when the VRF is full or only generate an event.
