Setting Up Devices for IOS XR Support
L2VPN in ISC 6.0 supports devices running Cisco’s IOS XR software. IOS XR, a new member of the
Cisco IOS family, is a unique self-healing and self-defending operating system designed for always-on
operation while scaling system capacity up to 92Tbps. In L2VPN, IOS XR is only supported on Cisco
XR12000 and CRS-1 series routers functioning as network provider edge (N-PE) devices.
In L2VPN, the following e-line services are supported for IOS XR:
•
Point-to-point ERS with or without a CE.
•
Point-to-point EWS with or without a CE.
The following L2VPN features are not supported for IOS XR:
•
Standard UNI port on an N-PE running IOS XR. (The attribute Standard UNI Port in the Link
Attributes window is disabled when the UNI is on an N-PE device running IOS XR.)
•
SVI interfaces on N-PEs running IOS XR. (The attribute N-PE Pseudo-wire On SVI in the Link
Attributes window is disabled for IOS XR devices.)
•
Pseudowire tunnel selection. (The attribute PW Tunnel Selection in the Link Attributes window is
disabled for IOS XR devices.)
•
EWS UNI (dot1q tunnel or Q-in-Q) on an N-PE running IOS XR.
•
Frame Relay/ATM and VPLS services.
To enable IOS XR support in L2VPN, perform the following steps.
Step 1
Set the DCPL property Provisioning\Service\l2vpn\platform\CISCO_ROUTER\IosXRConfigType to
XML.
Possible values are CLI, CLI_XML, and XML (the default).
Step 2
Create the device in ISC as an IOS XR device, as follows:
a.
Create the Cisco device by choosing Service Inventory > Inventory and Connection Manager >
Devices > Create. The Create Cisco Device window appears.
b.
Set the OS attribute, located under Device and Configuration Access Information, to IOS_XR.
Note
For additional information on setting DCPL properties and creating Cisco devices, see the
Step 3
Create and deploy L2VPN service requests, following the procedures in this guide.
Sample configlets for IOS XR devices are provided in
Appendix A, “Sample Configlets”
Defining a Service Provider and Its Regions
You must define the service provider administrative domain before provisioning L2VPN. The provider
administrative domain is the administrative domain of an ISP with one BGP autonomous system (AS)
number. The network owned by the provider administrative domain is called the backbone network. If
an ISP has two AS numbers, you must define it as two provider administrative domains. Each provider
administrative domain can own many region objects.
