MSDP group between Catalyst and Nexus?

[fjcardenas-1]

Is there compatibility to create an MSDP group between Catalyst 6509 switches and N7K switches? Any restrictions? Has anyone done this and works fine?

MSDP works fine between 6500 and Nexus, i do not see any issue. (until you have any special case around the design)

here is the basic guide :
