[c-nsp] Nexus 7K - Routing over vPC Peer-link between chassis

[Yham]

Hi All,

Could you please tell me what is the disadvantage of running routing
protocols e.g. iBGP between SVIs of two chassis over vPC peer-link? I heard
a lot that cisco recommend to use a separate link for layer-3 but why?

logically peer-link should be more reliable as generally it bundle with
multiple physical links.

Thanks in advance.

Regards
