Hi all, It was JUNOS version bug.
Now It's ok upgraded to JUNOS version 8.3
Tks.
>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?
