we all know that the TC message can broadcast through the whole network by MPR, now i want to restrict TC message broadcast through whole network.I wish the nodes which receive TC forward the TC based on some constraints.For example,every TC message has a flag,when the flag=1,the node forwards the TC,when the flag=0,the node does not forward the TC.I feel that i should modification the code which is responsible for forwarding the TC,But i can not find that which folder the code belongs to.wish you to understand me and help me.

Hi,

an OLSR mesh can only work when every node gets a copy of every TC...
maybe you can describe what you want to do, your idea sounds like a
way to break your mesh.

Hi,

but then the mesh "clusters" will not be connected to each other anymore, right?

(P.S.: please don't forget to CC the mailing list for your replies)

i have a very huge mesh ,i need cluster for the huge mesh,so i need restrict
the TC message inside the cluster.

Hi,

There are several options to split a mesh apart into multiple pieces,
both inside and outside olsrd.

You could (as an example) use iptables or ebtables to prevent sending
UDP on the olsrd port (698) between nodes of different clusters.
You could use different VLAN tags, different radio frequencies or
different encryption keys to completely separate them.

You could also use a different UDP port for each cluster (that would
be a setting inside Olsrd).

Thanks for your reply!
I have other methods to resolve the route between the different cluster
,first i consider the route inside the cluster.
