Hi dear all, I found something wrong with OSPF neighbor establishment.
OSPF network type is p2mp.
After make neighbore down and then recover the link, never established to Full state.
the remote M10i is always "init" state.
so I tried issue the "restart routing" command, then established OSPF neigbore Full.
also it's able to be recover this command action "commit" with some changing with configuration.
Is there anyone know this phenomenone?
below I attached the logg.
Tks.
