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

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

MgmtEth0/4/CPU0/0 unassigned Shutdown Down

MgmtEth0/4/CPU1/0 unassigned Shutdown Down

In a multiple (D)RP environments there is an option to configure a virtual management interface and
assign an IP address to it, so that the device is reachable via the same IP address no matter which
(D)RP is active. In such an environment, each (D)RP has its own IP address but it is not used in order
to access the device.

In order to get the virtual IP address, login to the device and run the command

show running-config

ipv4 virtual address

as shown in the example:
