I found the answer in an openbsd-cvs archive.
Ref. https://marc.info/?l=openbsd-cvs&m=151977078027087&w=2

Example command.
>$ doas ifconfig mgre0 tunneladdr 192.0.2.1

>$ ifconfig mgre
mgre0: flags=8800<SIMPLEX,MULTICAST> mtu 1476
        index 24 priority 0 llprio 3
        encap: vnetid none
        groups: mgre
        tunnel: inet 192.0.2.1 ttl 64 nodf
