192.168.101.11 rosenstein
192.168.101.12 kryptaroof-upper rb433 - ether3 management IP only !

192.168.101.25 RB493AH - spenger25 indoor testbed :)

management:

192.168.101.110 - nix_roof 
192.168.101.101 - panel@spenger25 (193.238.156.201)

on olsr router behind the 5 ghz devices there is following rule for ip assignment for better management of routerboards (e.g. useful for ssh-tunnel)

192.168.101.100+x

above shall mean if routerboard has 192.168.101.23 router attached to routerboard should have 192.168.101.123

best place to add this ip (on an fff-router) is to append /etc/init.d/S40network with

#routerboard management ip
ip addr add 192.168.101.1xx/24 dev vlan1

(Caution: this will not survive flashing the router again)

btw: if you have multiple (olsr) routers attached to the routerboard, than you setup is to be considered invalid, as it causes unwanted traffic to the routerboard network!

ips of range 192.168.101.200..254 are reserved for temporal usage only!

Geplant (Markus)

--> check freebone activities also!

Leopoldsberg - HP 4

Heunord antenna 2 - stp1 (28dbi grid dort schon vorhanden und ausgerichtet)

Liechtwicht - HP4 auf DUAL ausbauen (Teststrecke)

Bei Erfolg:

DUALLINK NIX - HO6 
DUALLINK HO6 - Liechtwicht
DUALLINK NIX - OEBV

vorersts duallinks vermutlich mit bonding, langfristig mittels ospf costs (das wenn auch im ganzen routerboard network ospf läuft)

Plans (Jan)

Create point to multipoint, fully redundant (OSPF setup) uplink in triangle:

KRYPTA-PELIKAN-HEUNORD

Capable of carrying 60-80 mbps traffic full duplex

    we need:
    3x ALIX 3c1 or RB433AH
    6x mini pci sparklan or R52
    3x ALU BOX for board, with 3xN-ufl pigtails
    3x MARS 25 DBI dual polarisation antenna
    6x pigtails ufl-n
    6x 2 meters of 5ghz (RF400) meter cable N-N   
    ---

Functional routerboard links:

heunord - spenger25

tadellos 30mbps
2x rb411´

heunord antenna 3 - VIVI (UPLINK for heunord)

temporary link, antenas not perfect aligned 18/18 mbps
08/12/01 antenna on vivi moved away, fixed in Novermeber
08/12/15 link deaktiviert, zu schlechtes signal
08/12/29 antenna on vivi fixed again (33db SNR), now 22/25mbit
always suffers from interferences with outher links, maybe minipci shielding, may improve this, or better antenna cables, or bigger distances between antennas,..

heunord antenna 3 - rosentstein

markus, tadellos, geplanter polarisationswechel und verbindung mit heunord antenna 2, to reduce airtime conflicts with VIVI-HEUNORD

heunord antenna 2 - liechtwicht

markus, war tadellos (40mbps) seit november08 etwas problematisch (nach Umbau, vmtl. schlechtes pigtail)
aber auch absichtlich möglichst hohen kanal, und kein rutbo-mode, und geringere leistung 
um heunord - VIVI nicht zu stören, momentan (12/16mbit)

heunord antenna 0 - garten94

markus, currently 25mbps (40 would be no problem)
turbo mode deaktivated, as it makes huge interferences with other links (even when on low tx-power)
very low tx power on both ends (as its only 200 meters anyways, and disturbs viv-heunord)

garten94 (rb433) - nord27 (rb411)

markus, 12km link, 28db grid on garten and 23 db antennabox
18mbit, very reliable, better than with heunord (which it was before), less interference with other 5ghz and with trees (-;

liechtwicht - hp4

markus, felix
19dbi gentlebox, 18dbi dual antenna, 30/18mbps, turbo-mode, noch nicht perfekt ausgerichtet
momentan kein duallink, aber ist geplant, sobald weitere dualantennen vorhanden(schon bestellt)

VIVI - HO6

2x RB532 - andi/markus
durch votivkriche sehr extrem eingeschränkte sicht, ca. 20mbit
26db gridantennen
