I've got over 30 offices dotted up and down the country. I need to create two additional vlans in each site. Currently I have all the offices connected to each other via MPLS from a third party. What I'd like to do is run OSPF in each office, so bearing this in mind would it be better to have the following vlans and incrementing subnets in each office:
VLAN 20 10.6.1.0 /27
vlan 21 10.7.0.0 /24
Or is there a better way to do it?
Thanks in advance
