[c-nsp] Nexus 7K vPC with Object Tracking

[Yham]

Hi Folks,

Topology is something like two N7K have two downstream N5K running dual
vPC. Each N7K is single homed with core. So since each N7K learns remote
networks for that only core link so if the link goes down the traffic black
hole because both N7K are not exchange routes.
I want to configure object tracking under vpc so if uplink core link goes
down, tracking bring down the downlinks toward N5K.

Is anybody using object tracking ? are there any drawbacks/limitations or
any design consideration.

Please share your thoughts.

Thanks & Regards
