Hi Steven,

you cant change or delete the vrf under the Mgmt interface.

leaf-5664-1(config)# vrf context VPC-PKL
leaf-5664-1(config-vrf)# exit
leaf-5664-1(config)# int mgmt 0
leaf-5664-1(config-if)# vrf member VPC-PKL
ERROR: VRF VPC-PKL cannot be used for mgmt0

leaf-5664-1(config-if)# no   vrf member management
ERROR: VRF management cannot be deleted from mgmt0 interface
leaf-5664-1(config-if)#
leaf-5664-1(config-if)# end

Instead of using the Mgmt interface for keep alive, you can use separate L3 interface between both the switches for Vpc keep alive. In that interface you can configure different VRF.

Thanks,

Muthu.

Dear Muthu,

Thanks for you confirmation, this is what i noticed i thought there is a way to change it.

Thanks

  I really don't see why you couldn't , its just a another routing instance and you are using it for a simple point to point link for the vpc keep alive.

Hi Glen,

i tried to configure it but it didn't take it, i think we can't change vrf managment under managment interface, Did you try it?

Thanks

There are some workarounds:
