~~~~
3
- config: when parsing prefix, check zero bits
4

    
5
- static: check validity of route destination?
6
- static: allow specifying a per-route filter program for setting route attributes?
7

    
8
- krt: rescan interfaces when route addition fails?
9

    
10
- tagging of external routes?
11

    
12
- when an identical route is received, don't trigger updates
13

    
14
- configure: --enable-ipv6
15
- configure: IPv6 on glibc 2.0?
16

    
17
- Makefile: install target?
18

    
19
- forgetting device routes???
20
- kernel syncer doesn't support reconfiguration
21
- filter-defined internal attributes
22
- netlink: realms
23

    
24
- bgp: wait on restart

Commands
27
~~~~~~~~
28
- showing of routing table as seen by given protocol
29

    
30
Documentation
31
~~~~~~~~~~~~~
32
- write doctool
33
- write documentation :|
34

    
35
Globals
36
~~~~~~~
37
- right usage of DBG vs. debug
38
- kill preconfigs?
39
- check dump functions
40
- cleanup debugging calls
41
- logging and tracing; use appropriate log levels
42
- check incoming packets and log errors!!
43
- check log calls for trailing newlines and log levels followed by comma
44
- check if all protocols set proper packet priorities and TTL's.
45
- replace all NUM, IPA and expr tokens by constant filter expressions
46
- try compiling with -Wunused
47
- does everybody test return value of sk_open?
48
- doc: references to RFC's we did follow
49
- protocols: implement CLI hooks and per-procotol CLI commands
50
- protocols: implement reconfigure hook
51
- protocols: use locking
52
- check use of system includes and sprintf()
53

    
54
Various ideas
55
~~~~~~~~~~~~~
56
- netlink: import Linux route attributes to our rta's, so that they can be filtered?
57
- config: executable config files
58
- client: access control
59
- io: use poll if available
60
- IPv6 router advertisements
61
- real multipath (doesn't seem to be simple at all :()
62
- fake multipath (even less simple)
63
- route recalculation timing and flap dampening [see RFC2439 for algorithms]
64
- aggregate engine: standard route aggregation and summarization [RFC2519]
65
- aggregate engine: injection of manually configured pseudo-static routes
66
- generate default route if any working BGP connection exists (aggregate engine again?)
67
- generate default route to IGP's (aggregate engine yet another time?)
68
- look at RFC 2386 (QoS-based routing)

OSPF
72
~~~~
73
	- refuse running on non-multicast devices
74
	- importing of device routes for networks where we don't run OSPF
75
	- check incoming packets using neighbor cache
76
	- RFC2328 appendix E: Use a better algorithm
77
	- automatic generation of external route tags (RFC1403)
78
	- RFC1587 NSSA areas
79
	- RFC2370 opaque LSA's
80
	- respect interface MTU and try not to create larger packets unless unavoidable
