Hello,

I have a question about the trunk connection between border and fusion router .

when provisionning overlay network , DNAC implement vlan range start to 300X for the connection vlan/vrf of the VN .

this is mandatory or you can change this range ?

As @Jonathan Cuthbert mentioned you cannot change the 300x vlans that get assigned for EBN<-->FR. If you have dual EBNs & dual fusions you could use the 400x series for your connections between EBNs and then use 200x series vlans for FR <--> "legacy" connections. Just be aware that DNAC will provision the default voice vlan as 4000 and the default critical vlan as 2047. Good luck & HTH!

The VLAN ranges used for the Fabric overlay SVIs and for the Border Automation L3 Hand-off are not user configurable.
