Link Bundle - MPLS TE & FRR Support

Hi Sir,
Platform Cisco 12406 PRP, current running IOS 12.0(32)SY3.
May I know what is latest IOS that can support MPLS TE & FRR over link bundle (L3 Etherchannel) ?
Regards

Hi,
12.0(33)S is the last IOS version for GSR and doesn't support this feature. New development focus on XR only and only few of them like 4B ASN are ported to 33S.

At which interfaces MPLS TE FRR supported?

Dear Sir!
In my last thread "Problem with FRR" I cannot to make FRR begin working.
So can you tell me (I cannot find it at www.cisco.com) at which interfaces are FRR supported?
Because in "Problem with FRR"
PE1 - 7204VXR with 12.0(29)S installed,
P1 - 7206VXR with 12.0(29)S installed, and use
Gi-interface to P2,
P2 - 3662 with 12.3.4(T) installed and use
Fa-interface to P1
Is it true, that FRR supports only on PoS interfaces?
Hope you help,
Maxim Denisov

FRR is supported on GigE interface. The issue is usually with failure detection. You need
to use RSVP Hellos or tune down the IGP hellos to ensure you quickly detect the link failure. Once you detect the failure, everything else works well.
Hope this helps,

MPLS TE FRR IOS support

Dear Sir!
Can you tell, is there some technology IOS for 36xx/37xx
to test MPLS TE FRR in our lab
(not in real network)?
Because we haven't 720x/7600 etc. in our lab.
Best regards,
Max

Hi Max,
In my opinion, MPLS FRR is not supported in 36xx/37xx.
Thanks,
Vikas

MPLS TE/FRR on ME 3600X

Hi,
Can ME 3600X provides 50-ms rerouting time upon link failure with MPLS TE/FRR?
There are many failure detection mechanisms cause the routers to switch LSPs onto their backup tunnels:
1.Interface Down Notification
(When a router’s link or neighboring node fails, the router often detects this failure by an interface down notification.
On a Packet over SONET (POS) interface, this notification is very fast.)
2.Loss of Signal
(Unlike POS interfaces, Gigabit Ethernet does not have any alarms to detect link failures. If a link is down
due to a cut cable or because the remote end shuts its laser, the optics module (GBIC or SFPs) on the
Gigabit Ethernet card detects a loss of signal (LOS). The LOS is used as a mechanism to detect the
failure and begin the switchover.)
3.Notification from the RSVP hello that a neighbor is lost
4.Notification from the Bidirectional Forwarding Detection (BFD) protocol that a neighbor is lost
5.Notification from the Interior Gateway Protocol (IGP) that the adjacency is down
6.For point-to-point link, PPP or HDLC keepalives
I know the 1st and 6th failure detection mechanism can't be applied with ME 3600X. Which failure detection mechanisms
cause ME 3600X to switch LSPs onto their backup tunnels to achieve 50-ms rerouting time upon link failure with MPLS TE/FRR?
My customer want to implement Ring Topology with ME 3600X to provide MPLS L2/L3 VPN services with MPLS TE/FRR.
What is the best pracetice design for Ring Topology with MPLS TE/FRR to provide link protection?
Regards,
Pipatpong

Hello Pipatpong
Below are the answers to your questions:
2. Should be able to detect and cutover.
3. Should be able to detect based on timer configuration. However the recommended value for RSVP hellos is 200 msec
From the config guide :
(http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/release/12.2_52_ey/configuration/guide/swmpls.html#wp1183359)
To prevent false detection of a down neighbor and unnecessarily triggering fast reroute, we recommend configuring a minimum frequency of 200 ms.
4. BFD support not yet available
5.Dont think IGP will be able to do 50ms on any platform.

Link bundle between 2950 & 7204VXR (NPE400)

Dear Team,
We have made etherchannel between Cisco WS-C2950T-24 L2 & Cisco 7204VXR (NPE400) router for load balancing purpose.
But the traffic from L2 switch to router is just being forwarded on single port & other port is idle while router is properly load balancing on both the ports.
Below is the configuration for both the switch & router.

Thanks in advance.
Nilesh.

Leo,
Thanks for the info. And please forgive me, I am not doubting your knowledge, just wanted to make sure about it. However, are you sure that channel numbers are supposed to be same? If that is the case, 2950 supports only up to 6 channels, and 3550 I think about 24 if I remember correctly. So what happens when I configure more then a 6 channels of 2950s into 3550. Next channel after six-th one would be 7, 8 and so on. However, I cannot configure channel # higher then 6 on 2950. With this, I am limiting 3550 to only 6 channels.
Now, I have not got experience in doing ether-channels. However, I was thinking logicly and thoughed that Cisco would not limit 3550s to 2950 limitation.
Please advise.
Thanks

C2600xm MPLS and QinQ support

Does anybody know an IOS version that supports both MPLS and QinQ support. Nearly all advance enterprise services 12.4 support QinQ and some 12.3T, but i believe that later versions of IOS 12.3 and onwards removed MPLS support. I could really do with finding both these features in the same IOS as it would greatly help me study. IOS selector is hard to trust as it doesnt appear to label MPLS support under some IOS which i know have the commands. Also certain 12.3T ios have been deferred which makes getting them to try hard to begin with.
So far i have tried the below.
c2600-adventerprisek9-mz.123-11.T.bin <-- QinQ no mpls
c2600-adventerprisek9-mz.123-26.bin <-- no QinQ
c2600-advipservicesk9-mz.123-4.T6.bin <--no QinQ
c2600-telco-mz.123-26.bin <-- MPLS but no QinQ
c2600-telco-mz.124-7.bin <- no MPLS
All the 12.4 IOS have had the tag-switching/MPLS commands removed.
Any help will be most appreciated!

Hi,
If your CE at both ends are routers, then you can configure both CE's with a Sub interface on the trunk link that is going towards PE. On this Sub interface of CEs you can configure IP address and also, if CEF is enabled on router and the interface then you can use mpls ip command on this sub interface and form LDP neighborship between both CEs over this l2 circuit.
Yes MTU size will have to be capable of supporting this increased packet size.

When you insert data from SQL Server into a linked server, then a distributed transaction should be started and here it seems this fails.

MPLS-TE FRR NNHOP protection (positioning of the NNHOP node)

Hi All,
I have a conception question about MPLS-TE FRR NNHOP protection. Does the NNHOP need to be along the path of the originally protected TE LSP but just downstream of the protected node?
David

Hi David,
Yes thats Correct. The Next Hop in a FRR TE LSP needs to be a long the path of the Protected TE LSP from the Headend Label Switch router to the Tailend LSR of the TE LSP.
You would normally have more than one Path OR a TE tunnel between the Headend and Tailend LSRs with FRR enabled. The Priority assigned to those tunnels selects the Primary Tunnel. and with FRR feature, if the first tunnel experience failure along the path with ANY of the intermediate next hops to the Tailend LSR of that LSP, the Secondary TE tunnel takes place with faster convergence time.

Mohamed

How to preempt MPLS TE FRR

I have an Explicit Path configured on a tunnel as 1 and a dynamic path as 2.

Hi,
By default, the re-optimization is around 1 hour. You can use the below command to speed up the re-optimization,
mpls traffic-eng reoptimize timers frequence <seconds>
With this command, the router after the seconds mentioned will check for better path for existing LSP (to see if primary path option is available) and use it if available.

MPLS TE FRR & some BFD

Hi,
I have a few questions:
1. If you have TE tunnel with FRR configured for it, what will trigger the switchover to backup tunnel?
In my mind:
a. Link Protocol down on the interface
b. RSVP signalling
Now two other problematic ones are:
c. IGP neighbor down over a protected link (will it trigger TE reroute WITHOUT using FRR, so IGP neighbors and FRR would be two completely different approaches?)
d. BFD. Is it activated on a specific protected link or on the LSP headend (tailend) to "test" the end-to-end LSP? It is mentioned in BFD docs that when used with TE FRR it can report tunnel down BEFORE the tunnel having sufficient time to be rerouted (because BFD would be acting so fast). Does this mean BFD allows end-to-end LSP testing?
2. More about BFD. The docs say that BFD itself just reports to the protocol employing its services (like IGPs and maybe TE) that the connectivity betweem two points BFD is responsible for is down. If BFD is configured over an interface, does this mean that when BFD senses lack of reachability but Link Protocol stays up (like Ethernet), will it actually bring down the Link Protocol on that particular interface?
If not, it is unclear why would docs also say that BFD is best deployed with Interface Dampening. Interface dampening would work in case Link Protocol flaps...
Thanks!
David

Hi David,
Pls see my what i feel inline...
a. Link Protocol down on the interface
b. RSVP signalling
1(a,b)
Here again RSVP hellos are used as a trigger to achieve the FRR rather than relying on the line protocol to go down.
Which provides us fast upto 50msec protection.
Afaik TE FRR can utilize BFD as its relatively less resource intensive than generating RSVP hellos.
c. IGP neighbor down over a protected link (will it trigger TE reroute WITHOUT using FRR, so IGP neighbors and FRR would be two completely different approaches?)
1(c)
Without using FRR the TE reroute would be pure Tunnel Reoptimization based on your IGP convergence towards your Tunnel TailEnd.
d. BFD. Is it activated on a specific protected link or on the LSP headend (tailend) to "test" the end-to-end LSP? It is mentioned in BFD docs that when used with TE FRR it can report tunnel down BEFORE the tunnel having sufficient time to be rerouted (because BFD would be acting so fast). Does this mean BFD allows end-to-end LSP testing?
1(d)
"BFD can help test end-to-end data plane only just like LSP ping, but there is currently no integration of the results and mapping of the same to control plane in MPLS. hence BFD with LSP ping is being preached. More details can be found at http://www.ietf.org/internet-drafts/draft-ietf-bfd-mpls-03.txt."
2. More about BFD. The docs say that BFD itself just reports to the protocol employing its services (like IGPs and maybe TE) that the connectivity betweem two points BFD is responsible for is down. If BFD is configured over an interface, does this mean that when BFD senses lack of reachability but Link Protocol stays up (like Ethernet), will it actually bring down the Link Protocol on that particular interface?
If not, it is unclear why would docs also say that BFD is best deployed with Interface Dampening. Interface dampening would work in case Link Protocol flaps...
2.
No BFD would not involve itself into getting the link down, it will only enable the protocol bootstrapping or using it to declare a failure.
Now assume if the link is bouncing up and down, or there are intermittent losses because of link intergity. Then BFD would keep sending up down messages to the protocol employing it. Hence if the integration is with Dampening, then such UP or DOWN messages can be considered as flaps in the configured interval and the interface can be dampened. The Dampening as a process would utilize BFD triggers for calculating flaps rather than the Line protocol based UP or DOWN triggers. Thus enabling us to achieve the upto 50ms recovery time which is generally provided by POS/SONET with APS.
HTH-Cheers,
Swaroop

MPLS LDP FRR

HI all,
I'm aware that you can enable MPLS FRR with RSVP. But how do you achieve FRR capabilities with LDP ??
Many Thanks

Hi Per,
From RFC 4090 (Fast Reroute Extensions to RSVP-TE for LSP Tunnels):
"A protected LSP is an explicitly-routed LSP that is provided with protection. The repair methods described here are applicable only to explicitly-routed LSPs. Application of these methods to LSPs that dynamically change their routes, such as LSPs used in unicast IGP routing, is beyond the scope of this document."
So currently there is no standard covering the required functionality. Imho the underlying reason is avoidance of routing loops. As TE tunnels have fixed starting and endpoints, you might reroute them in any way without creating loops, if preventing loops for the backup tunnel. When it comes to IGP based LSPs the problems are not that easy to solve. Example: R1-R2-R3 Assume the link from R2 to R3 is protected by a tunnel from R2 to R1 ... In IGP based LSPs a routing loop will be created and is hard to detect/avoid.
In case you have a feature request for your customer, drop me an email and we can discuss things offline.
Regards, Martin
