Modify Import/Export Route-target Under EVPN

Hi,

I'd like to consult whether adjusting the route-target under EVPN, which currently doesn't match between DCI and LEAF, to align with each other would impact the services being utilized. I discovered misconfigurations and seeks to rectify them but would like to understand the implications beforehand.

Scenario 1 involves modifying the route-target at DCI. Understanding that servers under LEAF cannot currently communicate with DCI, if we adjust the route-target to align, would it have any repercussions?

Scenario 2 entails modifying the route-target at the Leaf level. I'm concerned if it would affect communication between other Leafs or within the same Leaf.

2.1 Specifically, in the case where we need to adjust route-targets across all 4 Leafs, would it hinder communication?

2.2 Also, how long does it take for L2 to be learned between Leafs in such a scenario?

Thanks in advance.
