Cross-Platform Release Notes for Cisco IOS Release 15.1XB
April 16, 2012
Cisco IOS Release 15.1(4)XB8
Text Part Number OL-21523-01 Rev. I0
These release notes support Cisco IOS Release 15.1XB and are updated as needed. This release is based on Cisco IOS Release 15.1M&T. Use these release notes with Cross-Platform Release Notes for Cisco IOS Release 15.1M&T.
Note
Cisco IOS Release 15.1(1)XB2 introduces changes to LISP packet formats as prescribed by draft-ietf-lisp-07. LISP in Cisco IOS Release 15.1(1)XB2 is not backward compatible with the previous LISP releases. All LISP deployments must move to Cisco IOS Release 15.1(1)XB2 to retain compatibility.

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.

This section describes the following new and changed software features in Cisco IOS Release 15.1(4)XB6.
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.

There are no new hardware features in Cisco IOS Release 15.1(4)XB5.
New Software Features in Cisco IOS Release 15.1(4)XB5
This section describes the following new and changed software features in Cisco IOS Release 15.1(4)XB5.
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.

This section describes the following new and changed software features in Cisco IOS Release 15.1(1)XB2.
Support for 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.
Map 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.

New Software Features in Cisco IOS Release 15.1(1)XB1
This section describes the following new and changed software features in Cisco IOS Release 15.1(1)XB1.

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.
LISP 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.
LISP 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.

New Software Features in Cisco IOS Release 15.1(1)XB
This section describes new and changed software features in Cisco IOS Release 15.1(1)XB.
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:
