Which networks does L3VPN support

For S series switches (except S1700 switches), private network labels are distributed on an L3VPN using either of the following ways: 1. One label per VPN instance 2. One label per VPN route (default method) When a large number of VPN routes exist on a network, many private network labels are required if the default label distribution method is used. These private network labels may use up all entries. In this case, each VPN instance can be allocated a private network label to reduce the chip entries used.

When the switch functions as a PE, you can configure the static routing, RIPv1, RIPv2, OSPF, EBGP, and IS-IS multi-instances between the PE and the CE. The switch supports such networking modes as intranet, extranet, Hub&Spoke, CE dual-homing, and hierarchical MPLS BGP VPN.

Private network labels can be distributed in either of the following ways: 1.One label per VPN instance 2.One label per VPN route When a large number of VPN routes exist on a network, many private network labels are required if one VPN route is allocated with one label. These private network labels may use up all entries. In this case, each VPN instance can be allocated a private network label to reduce the chip entries used.
