[OLSR-users] invalid Link type between sym_NEIGH ?

[Daffys neko]

Hi all,

Here's my topology, 4 nodes connecting with Ethernet.
(Node A) 10.0.1.2 <--> 10.0.2.1 (Node B) 10.0.2.2 <--> 10.0.3.1 (Node
C) 10.0.3.2  <--> 10.0.4.1 (Node C)

When I look at the OLSR Packet in node C. I have
* a MPR Link with 10.0.2.2, ok
* but why the link with 10.0.4.1 is invalid ?? Shouldn't it be
SYM_LINK and SYM_NEIGH ?? What does invalid means for ethereal (04) ?
I don't undesrtand why the link is invalid ?
