Managed Vpns - Cisco SCE2020-4XGBE-SM Configuration Manual

Chapter 6 Configuring the Line Interface
VLAN
A single VLAN tag is supported per packet (no QinQ support).
Subscriber classification by VLAN tag is supported only in symmetric VLAN environments – i.e. where
the upstream and downstream tags of a flow are identical.
MPLS
MPLS/VPN-based subscribers with private IP support are a special case of classification by tunneling
information.
MPLS labels are supported up to a maximum of 15 labels per packet.
For more information regarding MPLS/VPN-based subscribers, see the

Managed VPNs

A managed VPN is a named entity, introduced in the same way that a subscriber is introduced, and
containing VPN mappings.
A managed VPN may contain several MPLS mappings or a single VLAN mapping. A VPN-based
subscriber contains a set of mappings of the form: IP@VpnName, where IP can be either a single IP
address or a range of addresses.
Managed VPN entities can be configured only via the SM. The SCE platform CLI can be used to view
VPN-related information, but not to configure the VPNs.
Private IP Addresses
Private IP addresses are supported only in the following modes, as these modes provide information
regarding the higher-level entity (VLAN or VPN) to which the IP addresses of the flow belong:
