BGPRouting

simple module

Implements BGP Version 4. TODO config file!

The model implements RFC 4271, with the following limitations:

NOTIFICATION message is not implemented
MinASOriginationIntervalTimer and MinRouteAdvertisementIntervalTimer are not implemented
Optional UPDATE message Path Attributes are not implemented
Optional Final State Machine events are not implemented

Implemented features by RFC 4271 chapters:

3. Summary of Operation (Routes & routing Information Base) -- implemented
4. Message Formats:

Header, OPEN, UPDATE & KEEPALIVE -- implemented
NOTIFICATION -- not implemented

5. Path Attributes:

ORIGIN, AS_PATH, NEXT_HOP -- implemented
MULTI_EXIT_DISC, LOCAL_PREF, ATOMIC_AGGRGATE, AGGREGATOR -- not implemented

6. BGP Error Handling -- not implemented
7. BGP Version Negotiation -- not implemented
8. Event for the BGP FSM -- implemented except optional ones
9. UPDATE Message Handling:

Decision Process -- implemented
Update-Send Process -- implemented except Controlling Routing Traffic Overhead

10. BGP timers:

ConnectRetryTimer, Holdtimer, KeepAliveTimer -- implemented
MinASOriginationIntervalTimer and MinRouteAdvertisementIntervalTimer -- not implemented
