Cisco Carrier Routing System (CRS-1)—Additional Information
This section contains additional information about the Cisco Carrier Routing System (CRS-1) and
includes the following topics:
• Cisco Carrier Routing System (CRS-1) Prerequisite, page 120
• SDR Support for CRS-1, page 120
• Multichassis Support for CRS-1, page 121

Cisco Carrier Routing System (CRS-1) Prerequisite

As a prerequisite for the CRS-1 VNE, install the Cisco IOS XR Manageability Package on top of the
IOS-XR version. In addition, the device configuration must contain the command, xml agent tty.
When creating the SNMP community, the SystemOwner should be specified.

SDR Support for CRS-1

Secure Domain Router (SDR) is supported as a separate independent VNE, with its own IP and login
sequence. When adding a SDR to Cisco ANA it is treated like any other network element, namely, it is
added as a new VNE using Cisco ANA Manage. The SDR IP address is attached to the active DRP of
the SDR (or the virtual IP, if it exists).
As a prerequisite for the CRS-1 VNE, install the Cisco IOS XR Manageability Package on top of the
IOS-XR version (XR 3.4 and 3.4.1). In addition, the device configuration must contain the command,
xml agent tty and when creating the SNMP community the SystemOwner should be specified.
The IP address, snmp read community and telnet login sequence must be defined.
Cisco ANA uses the management network (if available) to manage the devices. The CRS platform
assigns specific management interfaces on the RP modules (DRP in the case of SDR). In order to retrieve
the IP address of these management interfaces, login to the device and run the command show ipv4
interface brief | include Mgmt as shown in the example:
RP/0/RP1/CPU0:P1_CRS8#show ipv4 interface brief | include Mgmt
MgmtEth0/RP1/CPU0/0 1.60.34.104 Up Up
