Cisco ASR 1000 Series Aggregation Services Routers are Cisco routers deployed as managed service provider routers, enterprise edge routers, and service provider edge routers. These routers use an innovative and powerful hardware processor technology known as the Cisco QuantumFlow Processor.
Cisco ASR 1000 Series Aggregation Services Routers run the Cisco IOS XE software and introduce a distributed software architecture that moves many operating system responsibilities out of the IOS process. In this architecture, Cisco IOS, which was previously responsible for almost all of the internal software processes, now runs as one of many Cisco IOS XE processes while allowing other Cisco IOS XE processes to share responsibility for running the router.
Migrating to Cisco IOS XE Denali 16.3
The Cisco IOS XE Denali 16.3 Migration Guide for Access and Edge Routers contains key information and steps that will help ensure a successful migration from extant Cisco IOS XE 3S releases, Cisco IOS XE Denali 16.2 to Cisco IOS XE Denali16.3. It is critical that you read this information before you begin migration to ensure that you have completed all the prerequisites and that you understand the migration process.
For a list of caveats in this release, see the Caveats section in this document.

New Software Features in Cisco ASR 1000 Series Aggregation Services Routers for Cisco IOS XE Denali Release 16.3.2
The following are the new software features introduced in Cisco ASR 1000 Series Aggregation Services Routers for Cisco IOS XE Denali Release 16.3.2.
Bypass NAT Functionality
For detailed information, see the following Cisco document:
IWAN 2.2 - Multiple DMVPN Tunnel Termination
The IWAN 2.2 - Multiple DMVPN Tunnel Termination feature allows you to terminate two or more active DMVPN tunnels. The limitation of only one active tunnel per VRF on a device is not valid anymore. The routing protocol must be configured to ensure that there is one primary path and one or more secondary paths for a network. When Performance Routing (PfR) is used in conjunction with this feature, PfR is used as the primary path as well as the secondary paths so that all paths can be used in an active-active manner. Use the maximum-secondary-paths [eibgp | ibgp ] path command to configure this feature, where the path indicates the number of secondary paths a routing protocol is allowed to install. The range for path is from zero to 32.
Web User Interface - Configuring EIGRP Routing
Enhanced Interior Gateway Routing Protocol (EIGRP) is an interior gateway protocol suited for many different topologies and media. In a well-designed network, EIGRP scales well and provides extremely quick convergence times with minimal network trafficConfiguring EIGRP Routing.
Important Notes
The following sections contain important notes about Cisco ASR 1000 Series Aggregation Services Routers.
