[Olsr-users] Howto feed routing-table into OLSRd2?

[Bastian Rosner]

Hi,

just to make sure that this is not related to any IPv6 settings, i
adjusted the configuration to be IPv4-only and changed to logging behavior:

According to logs plugin lan_import loaded fine. Also inserting
neighbors route to table 123 succeeded:

13:48:48.293 INFO(olsrv2_routing)
src-plugins/olsrv2/olsrv2/olsrv2_routing.c 767: Set route 'src-ip - gw
169.254.1.2 dst 10.31.105.4 src-prefix - metric 2 table 123 protocol 100
if eth1.31 (5)' (0 0 -)
13:48:48.293 INFO(olsrv2_routing)
src-plugins/olsrv2/olsrv2/olsrv2_routing.c 935: Successfully set route
'src-ip 10.31.105.5 gw 169.254.1.2 dst 10.31.105.4 src-prefix - metric 2
table 123 protocol 100 if eth1.31 (5)'

Log also contains the following message:

13:52:29.683 WARN(os_routing)
src-plugins/subsystems/os_linux/os_system_linux.c 503: netlink recvmsg
error: No buffer space available (105)

Do i need to run a recent version of olsrv2 on openwrt-side to accept
attached-network routes generated by ubuntu's lan_import?

Cheers,
Bastian
