[OOR-Users] OOR | OpenWRT | "stretched" VLAN between sites

[Albert López]

Hello Jim,

The scenario you are proposing requires the implementation of layer 2 
support for LISP (basically be able to manage ARP packets). OOR only 
have level 3 support so this scenario is not supported.

Best regards

Albert
