Abstract Abstract
OSPFv2 and OSPFv3 include a reliable flooding mechanism to OSPFv2 and OSPFv3 include a reliable flooding mechanism to
disseminate routing topology and Traffic Engineering (TE) information disseminate routing topology and Traffic Engineering (TE) information
within a routing domain. Given the effectiveness of these within a routing domain. Given the effectiveness of these
mechanisms, it is convenient to envision using the same mechanism for mechanisms, it is convenient to envision using the same mechanism for
dissemination of other types of information within the domain. dissemination of other types of information within the domain.
However, burdening OSPF with this additional information will impact However, burdening OSPF with this additional information will impact
intra-domain routing convergence and possibly jeopardize the intra-domain routing convergence and possibly jeopardize the
