Layer-2 and L2VPN Features
All L2 and L2VPN features that are supported on physical ethernet or bundle ethernet interfaces are also
supported on Satellite Ethernet interfaces. The maximum number of bundles supported by Cisco ASR 9000
Series Router is increased to 510.
For more details on L2VPN features supported on the Cisco ASR 9000 Series Satellite System, see Cisco
ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Configuration Guide.

Layer-3 and L3VPN Features

All MPLS L3VPN features that are supported on ethernet interfaces such as GRE, netflow, and so on, are
also supported on the Cisco ASR 9000 Series Satellite System.
For more information on these features, see Cisco ASR 9000 Series Aggregation Services Router MPLS Layer
3 VPN Configuration Guide and Cisco ASR 9000 Series Aggregation Services Router Netflow Configuration
Guide.

Layer-2 and Layer-3 Multicast Features

All Layer-2 and Layer-3 multicast features, including IGMP, IGMP snooping, PIM, mLDP, MVPN, P2MP
TE, are supported on Satellite Ethernet interfaces, as they are supported on normal Ethernet and bundle ethernet
interfaces.
For more information on these features supported on a satellite system, see Cisco ASR 9000 Series Aggregation
Services Routers Multicast Configuration Guide.

which primarily pulls the address allocation to a more centralized NAT in the service provider network.
NAT44 is a technology that uses CGN and helps manage depletion issues of the IPv4 address space.
BNG supports the ability to perform NAT44 translation on IPoE and PPPoE-based BNG subscriber
sessions.
Note For BNG and CGN interoperability, configure the BNG interface and the application
service virtual interface (SVI) on the same VRF instance.
◦ Single Ethernet ports (non-bundle) on the CPE side of the Satellite node, connected to the ASR9K
through non-bundle configuration (static-pinning).
◦ Bundled Ethernet ports on the CPE side of the Satellite node, connected to the ASR9K through
bundle Ethernet connections.
