but the core routines are there and seem to be working.
o lib/ipv6.[ch] written
o Lexical analyser recognizes IPv6 addresses and when in IPv6
mode, treats pure IPv4 addresses as router IDs.
o Router ID must be configured manually on IPv6 systems.
o Added SCOPE_ORGANIZATION for org-scoped IPv6 multicasts.
o Fixed few places where ipa_(hton|ntoh) was called as a function
returning converted address.

* protocols: implement dumping of protocol-dependent rte attributes
|
|
|
|
- IPv6 support
|
|
|
|
- io.c: refuse old-style multicasts for unnumbered interfaces?
|
|
|
|
- counters (according to SNMP MIB?)
|
|
- better memory allocators
|
|
- 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?
|
|
|
|
- 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
|
|
|
|
- config: executable config files
|
|
- config: when parsing prefix, check zero bits
|
|
- config: reconfiguration
|
|
- config: useless rules when protocols disabled
|
|
|
|
- krt: rescan interfaces when route addition fails?
|
|
- krt: does PERSIST mode have any sense if kernel syncer is shut down as last?
|
|
|
|
- cmdline: implement
|
|
- cmdline: echo of debug/log messages
|
|
|
|
- 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.
|
|
- 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
|
|
|
|
Various ideas
|
|
~~~~~~~~~~~~~
|
|
- 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)
|
|
|
|
|
|
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
|
|
- 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
|
|
|
|
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)
