Abstract:
This document describes an optional ISIS extension that allows the
creation of IS-IS flood reflection topologies. Flood reflection
allows the creation of topologies where L1 areas provide transit
forwarding for L2 destinations within an L2 topology. It
accomplishes this by creating L2 flood reflection adjacencies within
each L1 area. The L2 flood reflection adjacencies are used to flood
L2 LSPDUs, and they are used in the L2 SPF computation. However,
they are not used for forwarding. This arrangement gives the L2
topology better scaling properties. In addition, only those routers
directly participating in flood reflection have to support the
feature. This allows for the incremental deployment of scalable L1
transit areas in an existing network, without the necessity of
upgrading other routers in the network.
