Abstract:
This memo documents an enhancement to the OSPF routing protocol, whereby
an OSPF router can stay on the forwarding path even as its OSPF software is restarted.
This is called "graceful restart" or "non-stop forwarding". A restarting router may not be capable of
adjusting its forwarding in a timely manner when the network topology changes. In order to avoid
the possible resulting routing loops, the procedure in this memo automatically reverts to a normal OSPF
restart when such a topology change is detected, or when one or more of the restarting
router's neighbors do not support the enhancements in this memo. Proper network
operation during a graceful restart makes assumptions upon the operating environment of
the restarting router; these assumptions are also documented.
