[Olsr-users] Slow reaction to change in bitrate/signal changes

I've been testing a setup with two VMs. Both of them running two Layer
2 links (IPv6 only) to each other. Very straight forward. To simulate
a link quickly dropping in quality I used the telnet Plugin to set the
rx_bitrate and tx_bitrate parameters.

I noticed however that this takes about 30 seconds to take effect and
traffic switching to the other link. This is *much* longer than I
would expect for OLSR to react to a link quality change. Are there
config parameters that should be adjusted here? Changing the
hello_interval down to 0.1 reduces this time to about 5 seconds -
which is much better but still fairly slow.
