Problem is in kernel vue of routing

ip route get fd99:1234:beef:cafe:fade::7000 from 
anycast fd99:1234:beef:cafe:fade::7000 from 
fd99:1234:beef:cafe:fade::7fff dev lo table local proto kernel src 
fd99:1234:beef:cafe:fade::7fff metric 0 pref medium


ip route replace fd99:1234:beef:cafe:fade::7000 from 
fd99:1234:beef:cafe:fade::7fff dev wig0 table local

evrything is going back to normal behavior.

Thanks for your support
