Has anyone managed to configure IS-IS routing with wireguard interfaces ?

I've added multicast address to AllowedIPs (AllowedIPs=224.0.0.0/24) but 
when I activate ip router isis on the wireguard interface, tcpdump only 
shows: unknown ip 8

expecting to see something like L1 Lan IIH, hlen: 27, v: 1, pdu-v: 1, 
sys-id-len: 6 (0), max-area: 3 (0)

or

L2 Lan IIH, hlen: 27, v: 1, pdu-v: 1, sys-id-len: 6 (0), max-area: 3 (0)


OSPF, RIP, EIGRP are working fine

Thanks!

IS-IS uses layer 2 while wireguard only provides layer 3 connectivity.
IS-IS will not work over wireguard.
