On
a
firewall
running
6.2.4.2
or
higher,
the
MTU
is
changed
on
the
interface
that
terminates
a
VPN
tunnel,
causing
the
numbered
tunnel
interface
MTU
to
change.
Administrators
are
advised
to
check
the
MTU
setting
on
both
VPN
peering
endpoints
to
ensure
that
the
values
match
so
that
OSPF
can
establish
neighbor
adjacency.
See
Knowledge
Base
article
SW10735
for
more
information
about
OSPF
and
tunnel
interfaces,
