Abstract:
When a link is being prepared to be taken out of service, the traffic
needs to be diverted from both ends of the link. Increasing the
metric to the highest metric on one side of the link is not
sufficient to divert the traffic flowing in the other direction.
It is useful for routers in an OSPFv2 or OSPFv3 routing domain to be
able to advertise a link being in an overload state to indicate
impending maintenance activity on the link. This information can be
used by the network devices to re-route the traffic effectively.
This document describes the protocol extensions to disseminate link
overload information in OSPFv2 and OSPFv3.
