Nuts and Bolts
10,000 foot view
- Protocols are recognizably similar in function and mechanism (unsurprising, given common heritage)
- Link state algorithms (network map is distributed, each router calculates routes independently based on the map)
- Two level hierarchies
- Designated Router on LANs
- Widely deployed (for some value of ÅgwideÅh)
- Multiple interoperable implementations
