Can two networks with the same subnet be connected to the same router in different VRF?
Clash Royale CLAN TAG#URR8PPP
Let's say I have the following four networks:
- Network A: 10.0.1.0/24
- Network B: 10.0.0.0/24
- Network C: 10.0.1.0/24
- Network D: 10.0.0.0/24
I would like to connect networks A and B together, and do the same between C and D (while A/B can't access C/D). With only a single router, could this be configured by setting two different VRF as shown below ?
If yes, what would happens if I set up BGP to exchange route between the two VRF, like in the following link: https://www.cisco.com/c/en/us/support/docs/multiprotocol-label-switching-mpls/multiprotocol-label-switching-vpns-mpls-vpns/47807-routeleaking.html#diffvrfs

For overlapping networks to communicate, you would need to use NAT. See this question and answers about that

You have two questions here.
Can two networks with the same subnet be connected to the same router
in different VRF?
Yes, as long as the two domains (VRF A and VRF B) do not communicate with each other. Think of a VRF as a virtual router.
What would happens if I set up BGP to exchange route between the two
VRF?
Things will not work, because hosts on Net A will never see hosts on C, and vice versa. Same for B and D.
