What are the network configurations for GRE IPv6 tunnels, I tried using some basic configurations to set up the tunnel across my Router and host machine, but somehow the tunneling interface at router end is not being created, any workaround will be appreciated

config interface 'mygre'
	option ip6addr 'fdbf:6dd6:68bb::1'
	option peer6addr 'fdbf:6dd6:68bb:0:8b93:5e27:6f69:838a'
	option proto 'grev6tap'
	option weakif 'br-lan'
	option ikey '06'
	option okey '05'
 
config interface 'mygre_static'
	option proto 'static'
	option ifname '@mygre'
	option ip6addr '21DA:D3:0:2F3B:2AA:FF:FE28:1'

sudo ip link add tun1 type ip6gretap remote fd86:2bac:7368::1 local fd86:2bac:7368::9e45:e16f:b9e2:2969 dev enx000e0986c5cd ikey 05 okey 06
sudo ip addr add 21DA:D3:0:2F3B:2AA:FF:FE28:2 dev tun1
sudo ip link set tun1 up
