[j-nsp] EX4500 and Nexus 5K STP

[Alex Martino]

Hi All,

I have to connect two Juniper EX4500 (in VC) to Cisco Nexus 5K VPC (two) and they currently run with RSTP+ and many many VLANs. Uplink ports will be ae on Juniper side and PO on Cisco side.

The documentations and forums aren't clear to me about the fact that VSTP is sufficent for clean interop or if I also need RSTP enabled and the native vlan id configured the uplink to handle STP on the Cisco native vlan 1.

Experience and insights are highly appreciated.

Thanks,
Alex
