Introduction
Cisco IOS XE Release 3.7.0Xx is based on Cisco IOS XE Release 3.7.0 and is a continuation of Cisco IOS Release 2.5.1XC. Many features and hardware that are supported in this software have been previously released to customers on other software releases. This release is intended exclusively for the deployment of the Locator/ID Separation Protocol (LISP) functionality on the routers that are listed in the "Supported Hardware" section on page 2 section.
For information on new features and Cisco IOS commands that are supported by Release 3.7.0Xx, see the "New and Changed Information" section on page 2.
System Requirements
This section describes the system requirements for Cisco IOS XE Release 3.7.0Xx and earlier releases and includes the following section:
Supported Hardware
Cisco IOS XE Release 3.7.0Xx and earlier releases support the following Cisco routers:
Cisco Aggregation Services Router ASR 1000 Series with:

New and Changed Information
This section lists the new hardware and software features supported by Cisco IOS XE Release 3.7.0Xx and contains the following subsections.
•
•
•
•
New Hardware Features in Cisco IOS Release 3.7.0XB
There are no new hardware features in Cisco IOS Release 3.7.0XB.
New Software Features in Cisco IOS Release 3.7.0XB
This section describes new and changed software features in Cisco IOS XE Release 3.7.0XB.
•
LISP Extended Subnet Mode Mobility Support
The LISP Extended Subnet Mode (LISP ESM) feature enables an IP host (virtual or physical) to migrate (move) between data centers where the subnet or VLAN is extended between these data centers using OTV or other L2 extension mechanisms.
SHA-2 Support
The SHA-2 feature enables the configuration of the SHA-2 cryptographic hash function for use in LISP Map-Register and Map-Notify messages. Prior releases only included the SHA-1 cryptographic hash function for these messages.
New Hardware Features in Cisco IOS Release 3.7.0XA
There are no new hardware features in Cisco IOS Release 3.7.0XA.
New Software Features in Cisco IOS Release 3.7.0XA
This section describes new and changed software features in Cisco IOS Release 3.7.0XA.

•
LISP Across Subnet Mode Mobility Support
The LISP Across Subnet Mode (ASM) feature enables an IP host (virtual or physical) to be migrated from one IP subnet to another IP subnet while retaining its original IP address.
LISP-Security Support
The LISP-Security (LISP-Sec) feature enables a set of security mechanisms that provide origin authentication, integrity, and anti-replay protection for Map-Request/Map-Reply mapping resolution exchanges.
LISP Delegated Database Tree
The LISP Delegated Database Tree (DDT) feature provides the ability to define a large-scale distributed database of LISP Endpoint Identifier (EID) space using a new type of LISP-speaking device known as a DDT node. A DDT node is configured to be authoritative for some specified portion of an overall LISP EID space, as well as the set of more specific subprefixes that are delegated to other DDT nodes.
LISP Locator Table Virtualization Support
The LISP Locator Table virtualization feature allows multiple LISP instantiations created in support of multi-tenancy to each be associated with their own routing locator address space reachable via a Virtual Routing and Forwarding (VRF) table.
LISP ALT Summary Route
The LISP ALT Summary Route feature enables an ALT-connected device to summarize and announce an aggregate prefix into the LISP ALT. This summary route can be announced in lieu of more-specifics to improve ALT scalability, and to simplify Map-Request handling.
LISP PETR Load Sharing
The LISP PETR Load Sharing feature adds priority and weight options to configured PETRs for configurable load sharing.
LISP Remote RLOC Probe
The LISP Remote RLOC Probe feature improves convergence times for LISP encapsulations by immediately sending triggered probes to remote RLOCs that undergo next-hop changes.
LISP RLOC Auto-Discovery
The LISP RLOC Auto-Discovery feature provides the ability to configure a LISP site with multiple xTRs to use dynamic provisioning for their RLOC interfaces (locators).
LISP Route-Import
The LISP Route-Import feature enables dynamic proxying of EID-space by a Proxy-ITR.
LISP Instance ID Support
The LISP Instance ID Support feature includes the following support:
•
ALT-less Proxy Ingress Tunnel Route support: Ability to configure LISP PITR functionality without requiring the PITR to be ALT-connected for EID-to-RLOC mapping resolution. This results in a simpler configuration of the PITR, and allows the PITR to use standard Map-resolution mechanisms for EID-to-RLOC mapping resolution instead of the ALT.
