-* router id
* right usage of DBG vs. debug
- TOS not supported by kernel -> automatically drop routes with TOS<>0
- default preferences of protocols: prefer BGP over OSPF/RIP external routes?
- all internal tables are in host order
- secondary addresses -> subinterfaces
+- check if all protocols set proper packet priorities and TTL's.
- filter: logging of dropped routes (?)
- limitation of memory consumption: per-process and total (?)
- route recalculation timing + flap dampening (?)
-- reconfiguration without restart of all protocols?
-- change of interface address: ??? (down and up?)
- "generate default route" switch for all IGP's
- running protocol on an interface:
- interface is not required to exist
- can specify a wildcard pattern or an interface list
-- re-configuration: restart of routing protocols (shutdown mode)
+- re-configuration: restart of affected routing protocols (shutdown mode)
- Check incoming packets and log errors!!
