Using this method, it is possible to effectively control from which nodes RSVP messages will be accepted by sharing the secret key with those RSVP neighbors. Any RSVP neighbor that does not belong to a security domain will have its messages rejected.
RSVP authentication software is responsible for carrying out the following tasks:
–
–
–
–
–
•
The following two types of packets that can arrive at the disposition-egress are normal EoMPLS data packets and VCCV packets. Both types are supported in this release. The VCCV echo reply is sent as IPv4 (meaning that the reply mode is IPv4). This reply is forwarded either as IP or MPLS, or a combination of both.
Cisco CRS-1 Software Features
•
The following commands were added:
–
–
•
•
•
•
–
–
In addition to the current MPLS-aware NetFlow, you can collect and export the IPv4 fields in the MPLS packet. You can also specify how many labels (up to 6) in the MPLS label stack should be used as key for the MPLS NetFlow. In order not to disturb the existing deployment of MPLS aware NetFlow, the current implementation of MPLS aware NetFlow remains the default behavior. The collection of IPv4 fields in the MPLS aware NetFlow and N-label are options to the MPLS flow record.
MPLS Aware Netflow commands added:

Important Notes
In certain countries, use of these products may be prohibited and subject to laws, regulations, or licenses, including requirements applicable to the use of the products under telecommunications and other laws and regulations; customers must comply with all such applicable laws in the countries in which they intend to use the products.
When upgrading a Cisco XR 12000 Series Router from Cisco IOS to Cisco IOS XR software, follow the upgrade instructions provided to minimize traffic impact. For detailed instructions, see the Upgrading from Cisco IOS to Cisco IOS XR Software on the Cisco 12000 Series Router, document for procedures.
Follow the instructions provided by Cisco for all card removal and replacement (fabric cards, line cards, fan controller and RP, and so on) to avoid impact to traffic. See the Cisco IOS XR Getting Started Guide for procedures.
If you intend to test beyond the combined maximum configuration tested and published by Cisco, please contact your Cisco representative to discuss how to engineer a large-scale configuration maximum for your testing.
Cisco SIP-600 line cards (for the Cisco XR 12000 Series Router) draw more power than previous line cards. Depending on the exact configuration of power entry modules (PEMs) and other cards in the chassis, there may not be enough power available when inserting a new card or removing a PEM. Before you insert a new card or remove a PEM, run the following command in admin mode:
RP/0/0/CPU0:router# adminRP/0/0/CPU0:router# show environment power-supply table48V CurrentR/S/I Module (V) (A)0/24/* PEM1 54 4PEM2 53 40/25/* PEM1 54 4PEM2 53 4Total Power Supplies: 3200WRedundant Power Supplies: 1600WWorst Case Power Used: 621WCurrent Power Used: 428WCurrent Redundant Power Available: 1172WCurrent Total Power Available: 2772WWorst Case Redundant Power Available: 979WWorst Case Total Power Available: 2579WPID Description Watts--- ----------- -----GRP-B Route Processor 38PRP-1 Cisco 12000 Series Performance Route Processor 60LC-4OC-3-POS-SM 4 Port Packet Over SONET OC-3c/STM-1 804OC3X/POS-MM-MJ-B 4 port ISE OC3 90...If you plan to insert a new card, locate the entry for the card to be inserted and note the power consumed by it. If this power is less than the figure given in Worst Case Redundant Power Available (the figure is displayed in the show environment power-supply table command output), the card can be safely inserted. As long as the Worst Case Redundant Power Available is not zero, a PEM can be powered down for replacement without impact.
Note
Caveats
Caveats describe unexpected behavior in Cisco IOS XR software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.
Open Caveats—Release 3.4.1
This section lists the caveats for Cisco IOS XR Software Release 3.4.1. The caveats are organized as follows:
•
•
Quality of Service (QoS) Units of Measure Changes
Since the default units of measure may no longer be the same, care must be taken when taking a configuration earlier than Cisco IOS XR Software Release 3.3.0 and applying it to Cisco IOS XR Software Release 3.3.0 or later. Table 7 lists the changes to QoS units of measure.
Note
Keywords cannot be inserted into the running configuration on a router running Cisco IOS XR Release 3.2.x in advance of the upgrade. An option is to edit the configuration offline, and add the necessary keywords.
Note
To remove a service policy from an input or output interface, use the no form of the service-policy command in interface configuration mode, as shown in the following syntax:
no service-policy {input | output}When the policy is removed from any interfaces, the edited policy is applied. See the following Cisco IOS XR command reference sections:
–
–
Platform-Independent Caveats
The following caveats apply to both platforms:
Note
•
Basic Description:
IA tunnel does NOT go down and come up on topo change in non-head area.
Symptom:
When IOS XR Release 3.4 MPLS Traffic Engineering node is a non-head area node and there is a topology change triggered either due to IGP link add/removal or any other topology change in the IGP (say) Level 1 to Level 2 for the links on that node. The inter-area tunnels originating from the Head and going via that link will NOT flap as a result of this topology change.
Conditions:
This behavior is seen in IOS XR Release 3.4 in a non-head area node and inter-area TE tunnel is being setup with loose hop in the path ERO.
Additional Notes:
Path verification and tunnel reoptimization indication are not done by the midpt ABR node. This is similar to the IOS behavior today. This feature will be added in a future release.
Workaround:
None.
•
Basic Description:
L2VPN: Control word cant be set if PW is established with cbit=0
Symptom:
Router not sending Control Word even when Controlk word is enabled.
Conditions:
If a PW is established with cbit=0, and later using config we enabled control word or if neighbor sends a label mapping with control word cbit=1, IOX will still send cbit=0.
Workaround:
The workaround is to delete and reconfigure the PW on both the PE's
•
Basic Description:
L2VPN: Support destination with Rtg ID different than LDP rtr Id
Symptom:
Can't establish PW to a non LDP router ID address
Conditions:
PW can be established on to the LDP router ID. Currently IOX does not support PW to non LDP router ID's
Workaround:
None
Cisco CRS-1-specific Caveats
The following caveats are specific to the Cisco CRS-1 platform:
•
Basic Description:
10GE requires XGXS reset after OIR of Xenpack (lane issue).
Symptom:
A 10 Gigabit interface may remain in a down/down state when attached to a no good port or with an external loopback applied.
The show controller tengige r/s/0/p mac output for the stuck interface will report the PLA is disabled and loopback is enabled.
RP/0/RP0/CPU0:crs#show controller tengig 0/0/0/3 mac
MAC (PLA) device is disabled
MAC (PLA) device is in promiscuous mode
MAC (PLA) device loopback is enabledIf the show controller tengige r/s/0/p xgxs command is issued, the DTE XGXS Status will report a value other than 0x801f. The Status of 0x801f indicates that the DTE XGXS is operating normally with the lanes in sync. A value other than 0x801f indicates a problem.

•
Basic Description:
netio process restarts when trying to restore config from disk.
Symptom:
An unexpected Netio process termination may occur when trying to restore configuration from disk or when changing the encapsulation of an interface from ppp to hdlc and vice versa.
Conditions:
Condition1: If the router has POS or serial interfaces and the configuration is cleared using following commands:
–
–
–
And then restored back from disk, the netio process can terminate.
Condition 2: If the encapsulation of serial interface is changed repeatedly from ppp to hdlc and viceversa, and if the packets are being sent out of that interface at the same time, the netio process can terminate
Workaround:
Workaround for Condition 1: When loading the configuration from disk, make sure the POS and serial interfaces are in a shut-down state. Once the configuration is loaded, the interfaces can be enabled again.
Workaround for Condition 2: If there is a need to change the encaps of a serial or POS interface, shut the interface before changing the encapsulation. The interface can be enabled after the configuration change has been made.

Workaround:
Its a one time flap and there is no work around.
Resolved Cisco IOS XR Software PSIRT-Related Caveats
•
Basic Description:
BGP flaps due to unknown attribute
Symptom:
Cisco IOS XR Software contains a vulnerability in the Border Gateway Protocol (BGP) feature. The vulnerability manifests itself when a BGP peer announces a prefix with a specific, valid but unrecognized transitive attribute. On receipt of this prefix, the Cisco IOS XR device will corrupt the attribute before sending it to the neighboring devices. Neighboring devices that receive this corrupted update may reset the BGP peering session.
Conditions:
Affected devices running Cisco IOS XR Software corrupt the unrecognized attribute before sending to neighboring devices, but neighboring devices may be running operating systems other than Cisco IOS XR Software and may still reset the BGP peering session after receiving the corrupted update. This is per standards defining the operation of BGP.
Workaround:
No workaround. Cisco developed a fix that addresses this vulnerability and will be releasing free software maintenance upgrades (SMUs) progressively starting 28 August 2010.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
