Scalability Issues
Flooding load--the only serious issue
- Full-mesh topologies are worst-case for both
- N^2 copies of each update (each of which is O(N) in size)
- Link failure: O(N^3) information
- Router failure: O(N^4) information
- IS-IS Ågmesh groupÅh hack provides backward-compatible way of pruning flooding topology
- OSPF has no solution without protocol change
