ACI MultiPod Remote Spine Discovery

[ITforever]

Hello,

We are setting up a multi-pod but not having a luck with discovering anything on the remote side (Pod 2). Our setup is as below:

APIC1/2---LF111/112---SP121/122---N7K_HO_1/2---N7K_BR_1/2---SP221/222---LF211/212

The config is as per below white paper:

https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c11-739714.html

APIC shows remote spines as inactive. Ping from N7K_BR_1/2 to SP221 is successful. But no IGMP Join is seen from the remote spines yet.

Date/Time on Remote Spines 6+ hrs behind. And the cerificate shows n/a.

Where is best to start troubleshooting? Any suggestion would be helpful.

Thanks.

What version is your ACI fabric running?  

What is the version of code your leafs and spines are running in pod2?

what model are your spines in pod2?

Time can be an issue, but I would also make sure that the leaf and spine nodes in POD2 are running a code that is not too far apart from POD1’s version.
