LSP hierrachy on IOS XRv

I am trying to configure LSP Hierarchy, starting with creation of Optical TE tunnels (http://www.cisco.com/c/en/us/td/docs/ios_xr_sw/iosxr_r3-7/mpls/configuration/guide/gc37te.html#wp1165592) on IOS XRv.
But I have some challenges, as it seems the 'switching transit' command is not there:
RP/0/0/CPU0:01-P2(config)#interface tunnel-te6
RP/0/0/CPU0:01-P2(config-if)#s?
service-policy show shutdown signalled-bandwidth
signalled-name soft-preemption
Is the LSP hierarchy supported on IOS XRv?
Thanks,
Krzysztof

hi matt,
MPP eventually gets programmed in the hardware forwarding as an ACL.
since XRv doesn't have that hardware layer as such, I dont think this feature will work "as expected" on real hardware.
You could check cisco live session id 2904 from sanfran 2014 and orlando 2013 that may have some good detail for you on the MPP operation and verification under the hood.
I am afraid this is a limitation of XRv.
Also there is a default TCP alllow all for 22, which results in the fact taht every interface effectively is capable of accessing the ssh control plane.
you may want to put the inband interface all and not allowing anything specifically. Bit surprised on the default TCP 22 there in your output, but this may be that restriction of XRv possibly.
cheers

IOS-XRv and HSRP: Supported?

Hey gang -
I'm building a virtual lab within a KVM hypervisor, and it includes 2 XRv images tied together across a VM switch image (Arista vEOS, but that's unimportant). The L2 connectivity is clearly there between the two routers:
RP/0/0/CPU0:r2#show cdp neighbors gigabitEthernet 0/0/0/6
Fri Apr 17 10:49:07.505 UTC
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge

r1    Gi0/0/0/6        149     R          IOS XRv S Gi0/0/0/6
And HSRP is able to sync up appropriately between the two of them:
RP/0/0/CPU0:r2#show hsrp br
Fri Apr 17 10:46:32.806 UTC
IPv4 Groups:
                        P indicates configured to preempt.

Gi0/0/0/6         1 100 P Standby 172.17.0.242    local          172.17.0.241
IPv6 Groups:
However, r2 (the secondary) can't ping the HSRP IP at all. It can ping the buddy router's IP address, but not the HSRP one:
RP/0/0/CPU0:r2#ping 172.17.0.242

Further, the switch VM that the two XRv routers are connected to can ping both of their IPs on Gig0/0/0/6, but can't ping the HSRP IP:

(Pay no mind to the horrendous latency; it's due to the way Arista wrote the VM).
So after all of that: should I expect HSRP to be fully supported with XRv? Or, like the L2 interfaces that are fully configurable, is it something that isn't supported? Did I, perhaps, forget to enable some bit within the XRv's config?
Thanks!

In order to get redundancy to run between two SLB switches, you need to configure HSRP between the two VLAN interfaces and then associate the standby name with the Cisco IOS SLB Virtual Server (Vserver). When using IOS SLB in an HSRP environment ensure that the active HSRP router (also active for IOS SLB) is receiving the return traffic for the IOS SLB connections.

IOS XRv Crashes on booting.

Hi Guys I have tried all versions of IOS-XRv for Virtual Box and VMware, but in both cases the IOX-XRv crashes as soon as it boots.

MPP on IOS XRv

Hi,
I have the following configuration on IOS XRv (5.3.0):
control-plane
management-plane
out-of-band
vrf MGMT
interface MgmtEth0/0/CPU0/0
allow SSH
allow Telnet
interface MgmtEth0/0/CPU0/0
cdp
vrf MGMT
ipv4 address 10.6.6.202 255.255.255.0
interface GigabitEthernet0/0/0/0
ipv4 address 10.6.6.203 255.255.255.0
With this configuration, I thought that MPP would only allow management (SSH/telnet) connections on MgmtEth0/0/CPU0/0. However, I can still ssh to the virtual XR instance on the 10.6.6.203 IP address in the global VRF. Is this by design or is it a feature?

IOS XRv LAB connectivity Issue

Dear
I faced issues in connectivity test (ping, trace route, CDP) between My IOS XRv router and another integrated routers cisco 7200 when i built my Lab on GNS3, any one faced these issue before and can help me ?
Interfaces is up
on the same subnet
i think the issue at setup IOS xrv on GNS3
Thanks

Your post is quite confusing, for several reasons.
First of all, you're talking about a Lenovo PC, but you have posted in the "iTunes for Mac" forum. Your profile indicates you have a MacBook Pro, but it's not at all clear if that enters into your scenario.
Secondly, it sounds like perhaps you're trying to use an iPad to do the "transfer an iMovie". If so, that is the source of your issue. The iPad cannot serve as a storage device to transfer iTunes data from one PC to another. You must use your computer's backup to do that. If you reformatted your laptop's disk, then it likely looks like a new computer to iTunes. You must restore the old backup to move the iTunes data to the newly formatted disk.

IOS XRv VM not booting

When I boot the VM it starts the boot process until it gets to the following error messages:

IOS XRv 5.1.1 LDP Interop with Junos

Hi
I have configured a Demo Lab
JunoS---------XRv5.1.1---------Ixia
I have setup on all ISIS and LDP
ISIS is working fine
however I am not able to get the LDP up, I have taken a packet capture and I see that Cisco is sending both in the hello and in the initialization packet a vendor-private tlv. as Ixia do not care the session is going up but it seems like juniper do not like that there for terminating the session.
I have tried to look if there is a way to turn that off, no luck!
will appriciate some informative comment.

I actually tried to look over into the trace but it was not very informative, my best guess was on the vendor-private in hello:

IOS-XR XRv

Hello,
Looks like the release notes for 4.3.2 indicate an upcoming download for XRv (XR4U?). 4.3.2 is available for download now for ASR9000 and CRS. Anyone know when we might see a download for XRv?
http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.3/general/release/notes/reln_432a9k.html#concept_15579287A4DE44C58EE16FD3399AB0C8
It will be nice to have a couple of these VMs running in a lab.

Folks,
I'm one of the XRv development leads. As has been mentioned on this thread already, Cisco IOS XR 5.1.1 software is *LIVE on CCO*.
This includes over 100 new feature offerings supported across multiple platforms including new platform support for XRv.
I've been collecting customer 5.1.1 links for XRv, and it's growing so I may add more (there are some minor changes to the release notes and the data sheet to come - bear with us as we don't release new platforms - even virtual ones - too often). Note that the demo image is free to use and the download works. The production images require the correct PIDs (I'll post more on this later).
I hope this product is useful, and we'll have many more features to come in future releases (HA for example...).
Thanks,
Rich Wellum ([email protected])

Hi everyone,
Have there been any SMU's released for XRv 5.1.1? I tried downloading and installing a SMU with regular ASR9K SMU's, but it complains:

It sure acts like a real XR router which is a good thing. Even if there were some dummy SMU's that would be cool. I need to apply some SMU's to my real ASR9k, and XRv would be perfect to practice on.
Thanks

Hi Tim,
Unfortunately I don't know this answer, but just as a heads up (if you don;t know it yet) you can test the installation without actually doing it with the command "install activate {pie name and location} test".

Segment Routing in XR 5.2.0?

Can anyone share some details on the Segment routing implementation in XR 5.2.0?
It seems that only Nodal segments gets label allocated. If Adjacency segments do get local labels, how is this information viewed?
I've configured this in addition to the normal isis ipv4 stuff:
router isis core
address-family ipv4 unicast
segment-routing mpls
interface loopback 0
address-family ipv4 unicast
prefix-sid index 4000
My topology is two P-routers with dual links between them, and two PE-routers dual-homed to the P-routers.
MPLS-forwading between loopbacks works fine based on the SR-assigned and-distributed labels.
My lab is running on IOS XRv 5.2.0
Another slightly related question: Is SR remote-lfa (draft-francois-segment-routing-ti-lfa-00) implemented (or getting implemented) yet?
/Mikkel

Hi Mikkel,
Check out the slideshare PPT link under the Miscellaneous tab of http://www.segment-routing.net/home
This site is kept up by the segment routing team.
At the end of the PPT is an alias you can email to get further information such as roadmaps if you are under an NDA.
Also note that XRv does not have all the functions of regular XR, so that may be why you are having an issue.
Thanks,

Ethernet over MPLS/VPLS

Hi,
I would appreciate if you answer my following questions :
- As you know EoMPLS is based on physical port, but how about VPLS?
- Could you tell me minimum router which supports VPLS?
- Any other solutions for transfer ethernet frames over MPLS except VPLS and EoMPLS?
- I think VPLS is better EoMPLS because it supports multipoint to multipoint ,is it true? could you please tell me VPLS advantage and disadvatage?
Regards,
M.Arshad rad

Ehlo ,
1)EoMPLS is available in port and vlan mode.Since VPLS
is actually using martini encapsulations ( both lasserre and kompella ) it is possible to use raw and tagged modes.
2)IMHO only Cisco router that supports VPLS now is 7600.Additionaly VFI can be only assigned to SVI.
3)Juniper CCC ( RSVP based ) - but obviously you won't use it since it's proprietary ( nevertherless it has nice feature like lsp-stiching ) and IOS couldn't signall it .
4) VPLS is designed to support p-to-mp and therefore
it's more complex.IF you don't need its features you can stick with raw p2p martini , which is relatively simple and widely implemented ( no problem for example to configure it between ios and junos boxes ).

IOS support for MPLS QoS as stated in RFC 3270 L-LSP

Hi,
does anybody know something about the degree of implementation of RFC 3270 (Multi-Protocol Label Switching (MPLS) Support of Differentiated Services), particularly on the classification based on Labels (L-LSP)?
From what is detailed on the CCO it seems that only Exp-bits based LSP are supported (configuring all links along the path for the proper data plane behaviour based on the Exp-bits values): E-LSP
Thanx in advance
Francesco

I guess, in PPP and LAN environments, E-LSP is the preferred method and in the ATM only L-LSP is possible. Maybe cisco chose to implement only the E-LSP for the LAN and PPP environments, i am not sure though.
Anyone knows this for sure?
Check out http://www.cisco.com/warp/public/732/Tech/mpls/docs/mpls_qos_jayk.ppt for more details on MPLS-QoS

IPhone 3GS (iOS 5) will not sync, stuck on *backing up* in iTunes 10.6.3.25

I recently updated iTunes to the latest update for Windows, since then, whenever I connect my phone and try to sync it just gets stuck in *backing up* for ages.. if I leave it it will be in backing up for hours. I cannot sync my phone or add any content now. I've been told to try and click the *X* in the progress window at the top of iTunes - but doing this does nothing but freeze iTunes for a few minutes - then it continues to *back up*... frustrating. Can anyone help?
Ta very much,
Chrissi
Windows 7 Home Premium, iPhone 3GS (iOS 5.1.1) and iTunes 10.6.3.25
I am also having this problem: https://discussions.apple.com/thread/4076906?tstart=0 Could they be related?
Message was edited by: ChrissiMoon

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 n above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if the problem has been resolved.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

Not working multitopology ISIS with IOS and IOS-XR

Hi everyone,
I've gon a problem setting up IPv6 routing with ISIS in the test network. There are four routers connected as shown on the image.
I've got problems setting up IPv6 routing in this topology. I tried single topology and multitopology ISIS. Neither of them works properly. Single topology simple does not come up when IPv6 is configured in ISIS. Multitopology yet comes up but uyields only working IPv4 roting. I can see that IPv6 ISIS RIB is buit by the routers, but it is not copied into the main routing table.
That's what I get in the multitopology mode:
All neignors are up.

I don't understand the following: Why R8 doesn't consider itself attached to Pseudonodes R8.01 and R8.03 in IPv6 topology? The same question about R9 and Pseudonodes R9.01 and R9.03 in IPv6 topology. R7 and R2 consider themselves as attached to Pseudonode R7.04, although R7.04 doesn't look much different from the rest of the Pseudonode LSPs in the database. This fact still doesn't allow them to calculate a correct RIB.
Am I missing something?

Hello,
Can you check on XR that you have option of enabling metric-style wide under ipv6 address-family.I'm not sure but i suppose you will also need to configure metric-style wide under ipv6 address-family as you are using multi-topology .IOS default run single topology and XR run default multi-topology.only need to be sure that you are running same topology and metric-style same on all router,in transition process like from multi to single or changing metric-style you can use "metric-style transition" option..

Ashish

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes, sync and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:
iTunes 10.5 for Windows: May see performance issues and blank iTunes Store
