ASR 9001 Cluster (Nv)

Dear ASR9000 experts,

If using 2 x ASR9001 with the Cluster technology (starting on the 4.3.0) can we assume that we can achieve processor redundancy ? For instance, if the active RP on the ASR9001 #1 fails can we assume that the standby RP on the ASR9001 #2 will assume the job in hands and that LC on the #1 and #2 chassis will continue forwarding NSR style ?

Thanks !

I would assume this as well

As it is not ready yet, we don't know the full story and if there are any caviat.

Thanks Alexei. When can we have absolutely sureness about it ? Only when 4.3.0 is released for the iron man ?

Aha, you know its code name, so you should have other information sources

But yes, the probability is high, but you never know.

Re: ASR 9001 Cluster (Nv)

Hello All,

Is it needed to buy any optics for the EOBC Links ? Or the built-in ports has all that is needed for the connection ?

Thanks!

SFPs would be needed to purchase separately.

Hello Alexei,

Have you more insight information to answer my initial post ?

Almost correct.  We have primary and backup DSC but we don’t have chassis standby RP.

the standby RP on the ASR9001 #2 will take over, but ASR #2 manages LCs in chassis #1 via RSP in chassis #1,  so if the first chassis fails due to RSP failure and we switch to the second chassis, we loose all the links on chassis 1.

if we switch due to a process crash for example and we don’t really have an RSP failure, then yes, RSP on the chassis 2 will take over with NSR and will manage both racks.

Hello Alexei, could you tell me what kind of SFP need for the Cluster Ports?

I ca use this one?

SFP-10G-SR=

What about the Inter Rack Links for these setup between the ASR9001?

Thanks

Hello Gerard,

No, this SPF is not good for EOBC. only 1G is supported.

any data 10G port can be configured as IRL link.

My 10G LR SFP+'s work fine on the cluster links so i guess it IS 10Gig capable.

Re: ASR 9001 Cluster (Nv)

Hi Alexei,

From my testing with XR 4.3.0 clustering on ASR9001 I drove the same conclusion: only 10G SFP+ was working for EOBC. What is the explanation? Does Giga SFP also work?

Thanks, kind regards

Re: ASR 9001 Cluster (Nv)

10G EOBC is NOT supported and NOT needed, the BW requirements for EOBC are very low. The optics may work and they may not, I have seen the same optics work in one chassis on 4.3.0 and not in another on 4.3.0.

Please see https://supportforums.cisco.com/docs/DOC-34114 for the list of optics which have been tested and are confirmed to work for EOBC.

Thanks,

Sam

Re: ASR 9001 Cluster (Nv)

Hi Sam,

Thank you for your reply. I'm aware of the doc but it doen't fully apply to ASR9001.

I'll test SFP-GE-L as EOBC SFP and let you know the result.

Thanks, kind regards,
Edi
