How do you handle overlapping vlans when using OTV between Data Centers. i.e. in Data Center 1 i have vlan 100 with ip address 10.10.100.0/24 and in Data Center 2 I have vlan 100 with ip address 10.20.100.0/24. I don't want to combine these into one network but keep them seperate when extending them between Data Centers.. Can OTV re-assign the vlans? or do i have to ensure the vlan tags are unique between the data centers?
