Core
~~~~
- socket open failure should not be fatal
- &&,||: priorities
- client: `?' in BGP masks
- filters: function for BGP path length
- static: allow specifying a per-route filter program for setting route attributes?

Globals
~~~~~~~
- right usage of DBG vs. debug
- logging and tracing; use appropriate log levels
- check incoming packets and log errors!!
- check log calls for trailing newlines and log levels followed by comma
- check if all protocols set proper packet priorities and TTL's.
- try compiling with -Wunused
- does everybody test return value of sk_open?
- protocols: implement CLI hooks and per-procotol CLI commands
- protocols: implement reconfigure hook
- protocols: use locking
- check use of system includes and sprintf()

Various ideas
~~~~~~~~~~~~~
- client: paging of output
- client: Ctrl-R eats one more enter
- bgp: timing of updates?
- netlink: realms
- netlink: import Linux route attributes to our rta's, so that they can be filtered?
- config: executable config files
- filters: user defined attributes?
- client: access control
- io: use poll if available
- IPv6 router advertisements
- real multipath (doesn't seem to be simple at all :()
- fake multipath (even less simple)
- route recalculation timing and flap dampening [see RFC2439 for algorithms]
- aggregate engine: standard route aggregation and summarization [RFC2519]
- aggregate engine: injection of manually configured pseudo-static routes
- generate default route if any working BGP connection exists (aggregate engine again?)
- generate default route to IGP's (aggregate engine yet another time?)
- look at RFC 2386 (QoS-based routing)
- cli: show tables?

OSPF
~~~~
	- refuse running on non-multicast devices
	- importing of device routes for networks where we don't run OSPF
	- check incoming packets using neighbor cache
	- RFC2328 appendix E: Use a better algorithm
	- automatic generation of external route tags (RFC1403)
	- RFC1587 NSSA areas
	- RFC2370 opaque LSA's
	- respect interface MTU and try not to create larger packets unless unavoidable
        - AS external LSAs are in topology database of every OSPF Area
        - Limit export rate of external LSAs (like Gated does)
        - Maximal distance is just 0xffff, but 2328 requires 0xffffff
