Abstract Abstract
OSPFv3 defines an option field for router-LSAs known as a R-bit in OSPFv3 defines an option field for router-LSAs known as a R-bit in
RFC5340. If the R-bit is clear, an OSPFv3 router can participate in RFC5340. If the R-bit is clear, an OSPFv3 router can participate in
OSPF topology distribution without acting as a forwarder to forward OSPF topology distribution without acting as a forwarder to forward
the transit traffic. In such cases, an OSPF router would only accept the transit traffic. In such cases, an OSPF router would only accept
traffic intended for local delivery. This draft defines R-bit traffic intended for local delivery. This draft defines R-bit
functionality for OSPFv2 defined in RFC2328. functionality for OSPFv2 defined in RFC2328.
