- fake multipath?
|
|
- config file: symbolic constants?
|
|
- counters (according to SNMP MIB?)
|
|
- generation of subnet mask ICMP's for v6?
|
|
- unaligned accesses?
|
|
- neighbor cache: local broadcast address?
|
|
- ipv4: recognize site scope addresses?
|
|
- ifdef out some debugging code?
|
|
- better memory allocators
|
|
- precedence of all packets (incl. TCP)
|
|
- default preferences of protocols: prefer BGP over OSPF/RIP external routes?
|
|
- all internal tables are in host order
|
|
|
|
- filter: logging of dropped routes (?)
|
|
- limitation of memory consumption: per-process and total (?)
|
|
- alloca
|
|
- adding of route: clear all bits not covered by masklen
|
|
- switch: generate default route only if at least one BGP connection exists
|
|
|
|
- route recalculation timing + flap dampening
|
|
|
|
- reconfiguration without restart of all protocols?
|
|
- change of interface address: ??? (down and up?)
|
|
- "generate default route" switch for all IGP's
|
|
|
|
- running protocol on an interface:
|
|
- interface is not required to exist
|
|
- can specify a wildcard pattern or an interface list
|
|
|
|
- timers - one-shot and periodic, resolution 1 sec, randomized
|
|
- re-configuration: restart of routing protocols (shutdown mode)
|
|
- route: originating AS
|
|
|
|
- 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)
|
|
- multicast on/off
|
|
- remember routes for all neighbors?
|
|
|
|
OSPF
|
|
~~~~
|
|
- Dijkstra: use Fibonacci heaps?
|
|
- 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
|
|
- BGP identifier aka router id
|
|
- 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)
