Hello Everyone,
I've recently installed and configure 2 * Unifi LR-6. One directly connected to the router (called mesh-lr6-gw) and on as a mesh node (called mesh-lr6-node1). My problem is certainly very simple (with the knowledge..)
I tried to set-up the VLAN part, and I were able to make it partially work (mesh is okay, batman too, and sometime one vlan among the both work).
While the mesh-lr6-gw, get an IP from the DHCP for each vlan interface, the mesh-lr6-node1 don't, why ? What is wrong with my set-up ? It seems like only one of the both bat get an ip. Sometime the vlan 300, sometime the 400. Is it related with the mac which is the same for both vlan (see ip a below) ? What are the good practice to solve that ? In such a way that only the router has dhcp server (one per vlan) and that each mesh node get multiple ips (one per vlan) ?

Notes:
- I'm tagging the eth0 on both nodes, since there will be a manageable switch connected to the lr6-node1.
- on the lr6-node1 i ran the
ip acommand thanks to connecting the node to a router.
Really hope that someone can help me ?
just in case: this topic follow another one with a question concerning the hardware selection for my mesh set-up Home set-up with OpenWrt and Ubiquiti
