Cross-Platform Release Notes for Cisco IOS XE Release 2.5.1X
November 1, 2010
Cisco IOS Release 2.5.1XC and Earlier Releases
Text Part Number OL-22449-01 Rev. D
These release notes support the Cisco IOS XE Release 2.5.1XC Early Deployment (ED) software release and earlier releases are updated as needed. This release is based on Cisco IOS XE Release 2.5.1. Locator/ID Separation Protocol (LISP) capabilities are currently supported on a range of Cisco routing and switching platforms via ED software releases. These LISP ED releases are intended only for deployments on LISP nodes and are not intended nor recommended for general production deployments throughout a customer's network.
Note
Cisco IOS Release 2.5.1XB introduces changes to LISP packet formats as prescribed by draft-ietf-lisp-07. LISP in Cisco IOS Release 2.5.1XB is not backward compatible with previous LISP releases. All LISP deployments must move to Cisco IOS Release 2.5.1XB to retain compatibility.

These release notes describe the following topics:

Introduction
Cisco IOS XE Release 2.5.1X is based on Cisco IOS XE Release 2.5.1. Cisco IOS XE Release 2.5.1XC and earlier releases are intended exclusively for the deployment of the LISP functionality on the routers that are listed in the "Supported Hardware" section.
For information on this new feature and Cisco IOS commands that are supported by Cisco IOS XE Release 2.5.1X, see the "New and Changed Information" section.

LISP Map Server and Map Resolver Functionality
Map Resolver
A LISP Map-Resolver is deployed as a LISP infrastructure component. A Map-Resolver receives LISP Encapsulated Control Messages (ECM) containing Map-Requests from LISP ITRs directly over the underlying locator-based network. The Map-Resolver decapsulates these messages and forwards them on the LISP-ALT topology, where they are then delivered either to an ETR that is directly connected to the LISP-ALT and that is authoritative for the EID being queried by the Map-Request, or to the Map-Server that is injecting EID-prefixes into the LISP-ALT on behalf of the authoritative ETR.
For more information, see the Cisco IOS LISP Configuration Guide at:
http://www.cisco.com/en/US/docs/ios/lisp/configuration/guide/LISP_configuration_guide.pdfMap Server
A LISP Map-Server is deployed as a LISP Infrastructure component. LISP site commands are configured on the Map Server for a LISP ETR that registers to it, including an authentication key, which must match the one also configured on the ETR. A Map Server receives Map-Register control packets from ETRs. When the Map Server is configured with a service interface to the LISP-ALT, it injects aggregates for the registered EID prefixes into the LISP-ALT.
The Map-Server also receives Map-Request control packets from the LISP-ALT, which it then forwards as a LISP Encapsulated Control Messages (ECM) to the registered ETR that is authoritative for the EID prefix being queried. The ETR returns a Map-Reply message directly back to the ITR.

Locator/ID Separation Protocol
Locator/ID Separation Protocol (LISP) is a next-generation routing feature. LISP can be used for any multi-homing environments while reducing operational complexities.
LISP creates a new paradigm by splitting the device identity, known an Endpoint Identifier (EID), and its location, known as its Routing Locator (RLOC) into two different numbering spaces. Splitting EID and RLOC functions yields several advantages that include improved scalability of the routing system through greater aggregation of RLOCs and improved multi-homing efficiency and ingress traffic engineering while avoiding site renumbering and reducing opex costs.
The Cisco IOS implementation of LISP supports the following Internet Drafts:

LISP Proxy Ingress Tunnel Router (PITR) Support
LISP Proxy Ingress Tunnel Router (PITR) support allows non-LISP enabled sites to communicate with LISP-enabled sites.
For more information, see the Cisco IOS LISP Configuration Guide at:
http://www.cisco.com/en/US/docs/ios/lisp/configuration/guide/LISP_configuration_guide.pdfLISP Proxy Egress Tunnel Router (PETR) Support
LISP Proxy Egress Tunnel Router (PETR) support allows two LISP enabled sites with a common address-family to communicate with each other when the intermediate network between does not use that address family. PETR support also allows a LISP enabled site to communicate with non-LISP enabled sites when it is necessary to bypass Unicast Reverse Path Forwarding (uRPF) mechanisms.
For more information, see the Cisco IOS LISP Configuration Guide at:
http://www.cisco.com/en/US/docs/ios/lisp/configuration/guide/LISP_configuration_guide.pdfLISP Support for IPv6
As a protocol, LISP was designed to operate in a mixed address-family manner. The initial Cisco IOS release of LISP did not implement IPv6 support. This release of Cisco IOS and Cisco IOS XE provides support for IPv6.
IPv6 support is provided for all LISP features available in these releases when LISP encapsulates IPv6 EIDs over IPv6 RLOCs or IPv6 EIDs over IPv4 RLOCs. This release does not support the LISP encapsulation of IPv4 EIDs over IPv6 RLOCs.
