Nuts and Bolts
Neighbor Adjacency Establishment
- IS-IS essentially uses its regular flooding techniques to synchronize neighbors (thatÅfs what flooding naturally does)
- Coarse database granularity makes this easy (just a few CSNPs)
- Transient routing issues can be reduced (albeit nondeterministically) by judicious use of the ÅgoverloadÅh bit (one of a number of opportunistic hacks)
