- IPv6 support
1999-08-04 03:35:01 +08:00
- io.c: refuse old-style multicasts for unnumbered interfaces?
- counters (according to SNMP MIB?)
- better memory allocators
1999-08-04 03:35:01 +08:00
- real attribute cache
- real neighbor cache
- default preferences of protocols: prefer BGP over OSPF/RIP external routes?
- static: check validity of route destination?
- static: allow specifying a per-route filter program for setting route attributes?
1999-08-04 03:35:01 +08:00
- rte_update: check whether all bits not covered by masklen are zero
- rte_update: debug mode
- netlink: import Linux route attributes to our rta's, so that they can be filtered?
- iface: SIOCGIFINDEX exists on glibc systems, but it doesn't work on 2.0.x kernels!
- socket: Use IP_RECVERR for BGP TCP sockets?
- OSPF: refuse running on non-multicast devices
1999-08-04 03:35:01 +08:00
- config: executable config files
- config: when parsing prefix, check zero bits
1999-08-04 03:35:01 +08:00
- config: reconfiguration
- config: useless rules when protocols disabled
- krt: rescan interfaces when route addition fails?
1999-08-04 03:35:01 +08:00
- krt: does PERSIST mode have any sense if kernel syncer is shut down as last?
- tagging of external routes?
- port to FreeBSD

Cleanup
~~~~~~~
- right usage of DBG vs. debug
- cleanup debugging calls
- logging and tracing; use appropriate log levels
- check incoming packets and log errors!!
- check log calls for trailing newlines
- check if all protocols set proper packet priorities and TTL's.
1999-03-30 04:46:00 +08:00
- replace all NUM, IPA and expr tokens by constant filter expressions
- try compiling with -Wunused
- does everybody test return value of sk_open?
- add references to RFC's we did follow
- protocols: implement CLI hooks
Various ideas
~~~~~~~~~~~~~
- real multipath (doesn't seem to be simple at all :()
- fake multipath (even less simple)
1999-03-02 01:51:29 +08:00
- 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)
RIP
~~~
- export-only and import-only mode?
- drop RIPv1 (Historic protocol)?
- Route Tag
- limit routing table xfer (frequency, only to neighbors)
OSPF
~~~~
- importing of device routes for networks where we don't run OSPF
1999-03-02 01:51:29 +08:00
- check incoming packets using neighbor cache
- RFC2328 appendix E: Use a better algorithm
- automatic generation of external route tags (RFC1403)
1999-03-02 01:51:29 +08:00
- RFC1587 NSSA areas
- RFC2370 opaque LSA's
- respect interface MTU and try not to create larger packets unless unavoidable
BGP
~~~
- aggregation, ATOMIC_AGGREGATE
- communities
- attributes must be sorted!
- re-export of NEXT_HOP attribute
- BGP session over currently down interface
- 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)
