Features Supported in the Satellite nV System

9 In the Dual-home scenario, for multiple satellites with a single physical ICL connected on hosts and
Satellite, both hosts must use same encapsulation and VLANs must be different from Satellite point of
view.
10 In the Dual-home scenario, for multiple satellites with multiple physical ICLs on one host, both hosts must
use same encapsulation and VLANs must be different from Satellite point of view.
11 In the Dual-home scenario, if the L1 and L2 Fabric connections are on the same host, there is no limitation
till same type of topology is used to connect both hosts on the Satellite side. There is no restriction on the
host side.
12 These service state synchronization are not supported.
Features Supported in the Satellite nV System
This section provides details of the features of a satellite system.

Satellite System Physical Topology

The satellite system supports the point-to-point, simple ring, hub and spoke physical topology, and the Layer
2 Fabric network topology for the ICLs between satellite switches and the host. These topologies allows a
physical Ethernet MAC layer connection from the satellite to the host. This can be realized using a direct
Ethernet over Fiber or Ethernet over Optical transport (such as Ethernet over a SONET/ SDH/ CWDM/
DWDM network).
These topologies also allow a satellite switch to be geographically at a separate location, other than that of
the host. There is no limit set for the distance, and the solution works even when the satellite is placed at a
distance of tens, hundreds, or even thousands of miles from the host.

Inter-Chassis Link Redundancy Modes and Load Balancing

The Cisco ASR 9000 Series Satellite system supports these redundancy modes:
• Non-redundant inter-chassis links mode - In this mode, there is no link level redundancy between
• Redundant inter-chassis links mode - In this mode, the link level redundancy between inter-chassis

• A satellite can support different encapsulations from both hosts till the layer 2 fabric connections
from both the hosts terminate on different satellite ICL links.
• A satellite can support multiple Layer 2 fabric connections with same VLAN on different physical
ICL interfaces.
• ANCP
• IGMP
• ARP
• DHCP
