- Once a VR is assigned with IPv4 address, it becomes IPv4 VR. After this, it will not accept any IPv6 address on that. A similar thing happens when IPv6 address is first assigned to a VR.
- We need to configure separate VRs for IPv4 address and IPv6 address when it was in the same VLAN.
- Basically, we can use the same VRID with different VLANs or same VLAN with different VRIDs.
- Apart from this, the same VRID can be used for IPv4 and IPv6 but not on the same VLAN.
