    Hi All

    we configure GRE over ipsec and running ospf on GRE interface.

    The ipsec tunnel is up, but GRE interface goes down sometime and can't come up again, we need to "clearp crypto ipsec sa" rebuilt the ipsec to bring the GRE up.

    We try to disable keepalive on gre tunnel, the GRE tunnel is up, but ospf neighbor down.

    Anyone can help?
