Port Partitioning; Bfd Over Satellite Interfaces; Bng Interoperability - Cisco ASR 9000 Series System Configuration Manual

Configuring the Satellite Network Virtualization (nV) System

Port Partitioning

The Cisco ASR 9000 Series Satellite system allows you to split or partition the satellite ethernet ports across
multiple ICL interfaces. You can split the satellite ports between 4 ICLs in Cisco ASR 9000v satellite and 2
ICLs in Cisco ASR 901 satellite.
Port partitioning is not supported for simple ring and Layer 2 fabric network topologies.
Note

BFD over Satellite Interfaces

Bidirectional Forwarding Detection (BFD) over satellite interfaces feature enables BFD support on satellite
line cards. Satellite interfaces are known as virtual (bundle) interfaces. BFD uses multipath infrastructure to
support BFD on satellite line cards. BFD over satellite is a multipath (MP) single-hop session and is supported
on IPv4 address, IPv6 global address, and IPv6 link-local address. The BFD over Satellite is supported only
on ASR 9000 Enhanced Ethernet Line Card and is supported in asynchronous mode. BFD over satellite is
not supported in echo mode.
Use the bfd multipath include location node-id command to configure Multipath BFD sessions. With this
configuration, all Multipath sessions including BFD over Satellite, are downloaded and hosted on the configured
line cards. Configure one or more line cards to allow hosting of Multipath BFD sessions.
For more information on configuring BFD over Satellite Interfaces, see the Implementing Bidirectional
Forwarding Detection chapter in the Cisco ASR 9000 Series Aggregation Services Router Routing
Configuration Guide. For complete command reference of the BFD commands, see the Bidirectional
Forwarding Detection Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router Routing
Command Reference.

BNG Interoperability

The BNG interoperability allows BNG to exchange and use information with other larger heterogeneous
networks. These are the key features:
• BNG Coexists with ASR9001:
• BNG Supports nV Satellite:
• BNG interoperates with Carrier Grade NAT (CGN):
ASR9001 is a standalone high processing capability router that comprises of a route switch processor
(RSP), linecards (LC), and ethernet plugs (EPs). All BNG features are fully supported on the ASR9001
chassis.
The only topology that is supported with BNG-nV Satellite is - bundled Ethernet ports on the CPE side
of the Satellite node connected to the ASR9K through non-bundle configuration (static-pinning). That
is,
CPE --- Bundle --- [Satellite] --- Non Bundle ICL --- ASR9K
To address the impending threat from IPv4 address space depletion, it is recommended that the remaining
or available IPv4 addresses be shared among larger numbers of customers. This is done by using CGN,
