Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Configure the local routing device so that it appears to be overloaded. You might want
to do this when you want the routing device to participate in IS-IS routing, but do not
want it to be used for transit traffic. Note that traffic to immediately attached interfaces
continues to transit the routing device. You can also advertise maximum link metrics in
network layer reachability information (NLRI) instead of setting the overload bit.
NOTE: If the time elapsed after the IS-IS instance is enabled is less than the
specified timeout, overload mode is set.
—Advertise maximum link metrics in NLRIs instead of setting the
advertise-high-metrics
overload bit.
allow-route-leaking —Enable leaking of route information into the network even if the
overload bit is set.
NOTE: The
allow-route-leaking
dynamic overload mode. Dynamic overload can occur if the device has
exceeded its resource limits, such as the prefix limit.
