ISC is a family of intelligent network management applications that helps reduce overall administration and management costs by providing automated resource management and rapid profile-based provisioning capabilities. ISC enables fast deployment and time to market of Multiprotocol Label Switching (MPLS) and Carrier Ethernet technologies. In addition, the ISC Traffic Engineering Management application is Cisco's exclusive planning and provisioning application for Cisco MPLS Traffic Engineering (MPLS-TE)-enabled routers. For Diagnostics, use MDE, which is an automated, decision tree analysis-based network management application that troubleshoots and diagnoses problems in MPLS Virtual Private Networks (VPNs). There are four separate applications in ISC 5.2, which can operate alone or as a suite in an L2/L3 Management Solution. These and Application Programing Interfaces (APIs) are all distributed on one product CD:
•Cisco ISC MPLS VPN Management (ISC:MPLS)
•Cisco ISC Layer 2 VPN and Carrier Ethernet Management (ISC:L2VPN/CE)
•Cisco ISC Traffic Engineering Management (ISC:TEM)
•Cisco MPLS Diagnostics Expert (MDE)

For more information about these features, see the "MPLS New Features" section.
Common Infrastructure New Features
All common infrastructure features are explained in the Cisco IP Solution Center Infrastructure Reference, 5.2.
This section includes the new features for multiple components that were added specifically in this release:
Cisco Configuration Engine Version 3.0
In addition to the previously supported versions of the Cisco Configuration Engine that manage an IOS device, this release now also supports version 3.0. This is explained in Appendix A of the Cisco IP Solution Center Infrastructure Reference, 5.2.
MPLS VPN Template Variables
New MPLS VPN template variables have been added in this release. These are specified in Table 6-4 in Chapter 6 of the Cisco IP Solution Center Infrastructure Reference, 5.2.
MPLS New Features
All MPLS features, including the new features since ISC 5.1, are explained in detail in the Cisco IP Solution Center MPLS VPN User Guide, 5.2.
Note All new IOS XR-supported features are supported for IOS XR versions 3.6.2 and 3.7.1 only.
The following MPLS VPN enhancements were added specifically in ISC 5.2:
The following MPLS VPN enhancements were added in the limited release ISC 5.0.4:
Note These features are not supported for Multi-VPN routing/forwarding instance for Customer Edge device (MVRFCE) policies and service requests, with the exception of the OSPF to BGP Redistribution feature.
BGP Route Map for IOS
ISC now supports the addition of a route map field for IOS devices with BGP, as the PE to CE protocol. The IN and OUT route map name can be specified. If Site of Origin (SOO) is enabled in the service request level, the Route Map/Policy In text box is grayed out and the Route Map/Policy In value takes the name of the SOO during deployment time.
Carrier Supporting Carrier on IOS XR for the BGP Protocol
The Carrier Supporting Carrier (CSC) feature enables a service provider to carry the traffic of a different service provider across its MPLS network. In ISC, the customer carrier PE device is modeled as a CE device and the backbone carrier PE device is modeled as Network-facing Provider Edge (N-PE) device. An MPLS Service Request with the CSC option can be created with these PE and CE devices.
You can configure the CSC feature on IOS XR PE devices. The CSC service is applicable for the following PE-CE link configurations:
The CSC service is applicable for the BGP PE-CE routing protocol.
eBGP—Community Strategy for Additional Route Support
ISC now supports two additional route-policy commands. You can specify the "in" and "out" policy name in a text field. These attributes are set when BGP is chosen as the routing protocol in the policy.
Note This option is only available when the PE-CE routing protocol is BGP.
ISC allows the BGP neighbor send-community command to be configured on the PE device for both IOS and IOS XR. This is available for both IPv4 and IPv6 eBGP neighbors on IOS XR PE devices. The Standard, None, Extended, and Both attributes are supported.
Note This option is only available when the PE-CE routing protocol is BGP.
eBGP—Site of Origin
The ISC graphical user interface (GUI) previously supported eBGP Site of Origin for IOS. In this release, eBGP Site of Origin is additionally supported only for IPv4 eBGP neighbors on IOS XR PE devices.
IOS to IOS XR Migration
For assistance in migrating services deployed on IOS devices to IOS XR devices, contact Cisco Advanced Services.
IOS XR Support Added
The following features are no longer just supported on IOS. They are now also supported on IOS XR, with the stated exceptions:
•BGP Multipath Configuration
–The maximum number of paths supported for IOS is 1 to 32 and for IOS XR the maximum number of paths supported in 2 to 8.
–Subsuming is now introduced for modification of all services requests with shared multipath attributes. This is new for both IOS and IOS XR.
Note Import paths are supported in IOS but not in IOS XR.
•eBGP Advertisement Interval
Multilink Frame Relay Support
The MLFR interfaces are supported on IOS XR devices. As with the previous support for IOS devices, ISC does not set up the MLFR interface, ISC provisions the layer 3 service on the MLFR interface.
Multicast Support for IPv6
ISC allows the following on IOS XR PE devices running release 3.7.0 or later: a multicast VPN to be deployed on an IPv6 PE-CE link and multicast to be enabled during the creation of the VPN routing/forwarding instance (VRF) object.
When creating a VPN or a VRF object, you can enable multicast for IPv4, IPv6, or both. You can enter IPv6 addresses as static Rendezvous Point (RP) addresses if IPv6 multicast is enabled during the creation of a VPN or VRF object.
You can also modify an existing VPN or VRF object to enable multicast for IPv4, IPv6, or both. When IPv4 multicast is enabled, all deployed service requests containing IPv4 links of the same VPN or VRF are moved into Requested state.
In addition, you can specify within the MPLS service request whether you want to enable multicast for IPv4, IPv6, or both on a given MPLS link.
When IPv6 multicast is enabled, all deployed service requests containing IPv6 links of the same VPN or VRF are moved into Requested state. If IPv4 is previously configured and only IPv6 multicast is enabled in a VPN, only the service requests with IPv6 links are moved into Requested state.
You can modify an existing VPN or VRF object and add IPv6 static RP addresses when IPv6 multicast is enabled. Any service requests already in Deployed state are then moved to the Requested state.
You can create a service policy or an MPLS VPN link in the service request with IPv6 Numbered or IPv4+IPv6 Numbered as the IP addressing scheme and a multicast VPN or a VRF with multicast enabled.
Multiple IPv6 Address Configuration
ISC supports multiple IPv6 addresses on the PE interface for IOS XR PE devices.
OSPF to BGP Redistribution
ISC now supports redistribute OSPF addition of a route policy. Previously, this configuration was hard-coded. ISC supports taking the values from the GUI and putting them into the device configuration. Special characters are taken as is, with no GUI validation being performed.
The following features are supported only for IPv4 routing on IOS and IOS XR PE devices:
•Redistribute OSPF route policy
•Redistribute OSPF match internal
•Redistribute OSPF match external
The following warning messages can be displayed and work only for IOS XR PE devices:
•Keep OSPF process for the Interior Gateway Protocol (IGP) as a separate process
•DCPL property to set the maximum number of OSPF processes (mpls\ospfProcessLimit)
•OSPF process identifier (ID) check
OSPF Protocol—New Settings
You can specify an OSPF domain ID on a PE or you can use an OSPF domain ID from a VRF or VPN.
Remote 4-Byte BGP AS Number Support
ISC supports a remote 4-byte autonomous system (AS) number in the format [0-65535].[0-65535]. As an example: 100.65535. This remote 4-byte AS number is supported as a CE BGP AS number in a service policy and as a CE BGP AS number in a service request. If the platform does not support a remote 4-byte AS number, the service deployment fails.
The previously supported 2-byte integer values are also supported as valid AS number values.
Route Distinguisher Format Addition
You can now configure an RD in ipaddress format on IOS and IOS XR PE devices. For IOS XR, only the IPv4 address format is supported. The new RD format is supported for creation and modification of an independent VRF, a VRF service request, and an MPLS service request, not an MPLS policy.
