BPDU filter

[mohammedrafiq]

Hi,

I have seen this topology (attached) in Cisco best practice datacenter design.My question is, if your two DC are connected over layer2 links then why you would disable BPDU filter ?

We do have same topology ,Two DC's connected over layer2 links(10+10G) in one vPC.

Hello,

In general, the BPDUFilter feature is used to split a (formerly) single STP domain into two independent STP domains so that each of them can have its own set of spanning trees, roots and active links, and topology changes in one domain do not propagate to the other domain, neither do they influence it. This is done to prevent one datacenter topology from influencing the other datacenter.

Of course, activating the BPDU FIlter effectively disables STP on the links configured with this feature. A great care has to be then taken to make sure that no switching loops ensue as a result.

Can you post the URL to the design document?

Best regards,

Peter

this looks like a nexus DC design.

some of the advanced features of nexus requires that STP is disabled

Hi,

Yes it is from Nexus DC design, but what advanced feature required STP disabled?

Thanks .
