Olsr Daemon

The OLSR.org OLSR Daemon (olsrd) is an implementation of the IETF RFC 3626: Optimized Link State Routing Protocol.

TBD (to be documented)

Hello...

yes YOU.

we really need someone willing to write a little bit about olsrd1 (history, usage, plugins, whatever) in this wiki.

Contact us on the OLSR.org developer mailing list if you are interested!

Dependencies

You need flex and bison to compile olsrd.

Compilation

After downloading the source of olsrd, you use a GNU compatible make file to compile both olsrd and its plugins:

# make build_all

Be careful that you use the shared object files (see ./lib/<name-of-plugin> directories) compiled from the same source as the main executable, otherwise it will not work.

Configuration

See OLSR network deployments for some example configurations for olsrd.

Plugins

There is a couple of plugins to equip olsrd with additional capabilities. Most of them have their own README file in their own subdirectory.

arprefresh	fills the local ARP table based on the incoming OLSR traffic
bmf	Basic Multicast Forwarding, which gives some form of local multicast distribution
dot_draw	creates dot draw compatible data from topology
dyn_gw	dynamically switches HNAs on/off based on external connectivity
dyn_gw_plain	dynamically switches HNAs on/off based on an IPv4 routing entry
httpinfo	provides internal OLSR information through a HTTP port
info	meta-plugin, common code base for txtinfo and jsoninfo
jsoninfo	provides internal OLSR information in JSON format
mdns	forwards MDNS packets in OLSR control messages
mini	example plugin
nameservice	provides a DNS between OLSR nodes by flooding the information every few seconds
p2pd	Distribution tree based multicast plugin
pgraph
pud	SNMP interface for olsrd
quagga	Integrates olsrd routes into Quagga
secure
sgwdynspeed	dynamic gateway speed for 'smart gateway' mechanism
txtinfo	provides internal OLSR information in text format
watchdog	overwrites a file every few seconds to allow an external process to see if olsrd is still alive
