Core
~~~~
* right usage of DBG vs. debug
* cleanup debugging calls!
- TOS not supported by kernel -> automatically drop routes with TOS<>0
- use -freg-struct-return ?
- fake multipath?
- replace all NUM's by expr's
1998-11-29 14:51:47 +00:00
- config file: define ipaddr constants?
- counters (according to SNMP MIB?)
- ifdef out some debugging code?
- better memory allocators
- default preferences of protocols: prefer BGP over OSPF/RIP external routes?
- secondary addresses -> subinterfaces
1998-10-19 18:18:12 +00:00
- check if all protocols set proper packet priorities and TTL's.
- better default protocol names
- config: comments at end of line -> explicit ';' needed?
- remove post-config hooks?
- command-line arguments: name of config file
- static: check validity of route destination?
- static: device routes
- filter: logging of dropped routes (?)
- limitation of memory consumption: per-process and total (?)
1998-11-29 14:51:47 +00:00
- adding of route: check whether all bits not covered by masklen are zero
- switch: generate default route only if at least one BGP connection exists (?)
- route recalculation timing + flap dampening (?)
- "generate default route" switch for all IGP's
- Check incoming packets and log errors!!
RIP
~~~
- RIP: export-only and import-only mode?
- drop RIPv1 (Historic protocol)?
- Route Tag
- limit routing table xfer (frequency, only to neighbors)
1998-11-29 14:51:47 +00:00
- multicast on/off (per interface)
- remember routes for all neighbors?
OSPF
~~~~
- point-to-point interface with address: advertise as stub network
- static routes: stub networks?
- modes: PtP, PtP-unnumbered, Broadcast, NBMA, point-to-multipoint
- importing of device routes for networks where we don't run OSPF
- tie breaking for equal type 2 ext metrics by using internal (type 1) metric
- SPF tree recalc timing (per-area timers?)
- aggregation: specify network list for each area
- stub area: either no external routes or only default route
- automatic generation of external route tags (RFC1403)
BGP
~~~
- in, local, out RIB
- maxsize=4096
- detection of loops
- aggregation, ATOMIC_AGGREGATE
- communities
- confederations
- attributes must be sorted!
- re-export of NEXT_HOP attribute
- BGP session over currently down interface
- route flap dampening?
- LOCAL_PREF attribute
- error notification received -> log error
- set TTL to 1 (configurable?)
- consulting IGP for next-hop information? (what if it changes?)
- inter-advertisement delay???!
- normalize (sort) incoming AS-SET's
- maximum length of AS paths
- expected neighbor AS
- hold time
- idle timer after error: initial value, exponential growth, maximum value
- import of IGP routes (use external route tags from OSPF)
