I'm usig frr routing with eigrp over wg

EIGRP: eigrpd 3.1-dev starting: vty at 2613
EIGRP: interface 192.168.123.1 [10] join EIGRP Multicast group.
EIGRP: interface 172.16.223.2 [15] join EIGRP Multicast group.
EIGRP: Neighbor 172.16.223.1 (wg0) is pending: new adjacency
EIGRP: Neighbor(172.16.223.1) adjacency became full

but it can be used as unicast specifing the neighbor, but with no 
interface for the moment, is under development
