How to reproduce

when i plug out wan wire,gre_0 interface will del ,ifconfig cant find gre_0 
then `route -n`, cant find other route's br-lan route info,that is right 
then i plugin wan wire,gre_0 will up after few seconds,
but ospf cant re update the other route's route info,and cant find neighbor in cmd `show ip ospf neighbor` 

Expected behavior

ospf and frr can regenerate other route's info

Actual behavior

after gre_0 restart,frr cant find ospf neighbor ,and cant generate other route's info
