Abstract:
Many OSPFv2 or OSPFv3 deployments run on overlay networks provisioned
by means of pseudo-wires or L2-circuits. When the devices in the
underlying network go for maintenance, it is useful to divert the
traffic away from the node before the maintenance is actually
scheduled. Since the nodes in the underlying network are not visible
to OSPF, the existing stub router mechanism described in [RFC3137]
cannot be used.
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 in the underlying network devices.
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.
