[Olsr-users] max packet size

[Evgeni Bikov]

Hi,
I'm using OLSR 0.6.0 on interfaces with MTU = 2304.
Internal MAXMESSAGESIZE value is set to 1500 by olsr internal default:
#define MAXMESSAGESIZE          1500    /* max broadcast size */


In my mind, maximum size of broadcast packet in the system is about 1500. I
can be wrong, but It corresponds with the fact that packet parser calls
recvfrom with buffer size of 1504.
Unfortunately in the case of pretty numerous and dense topology I can
observe packets of unexpected sizes (>2000).
Can u please clarify this for me? What mechanism in olsrd limits broadcast
packet size?

Thanks in advance.
