Hi again!
 
I discovered part of the problem, but another one emerged.
I was using a shared nics on each node which somehow was filtering some packets. The solution to the problem was to use dedicated nics with vlan.
 
Is there any difference to using vlans in the freertr hardware file?
 
[rtr-hw example]
hwid r2
proc ifc1.sh /rtr/rawInt.bin eth0 20002 127.0.0.1 20001 127.0.0.1
int eth1 stat eth fa:16:3e:e1:52:6a 127.0.0.1 20001 127.0.0.1 20002
proc ifc2.sh /rtr/rawInt.bin eth1 20004 127.0.0.1 20003 127.0.0.1
int eth2 stat eth b8:ce:f6:af:83:42 127.0.0.1 20003 127.0.0.1 20004
proc ifc3.sh /rtr/rawInt.bin eth2 20006 127.0.0.1 20005 127.0.0.1
int eth3 stat eth b8:ce:f6:af:83:43 127.0.0.1 20005 127.0.0.1 20006
....
 
r1#show lldp neighbor
interface hostname iface ipv4 ipv6
ethernet2 r2 ethernet2.100 192.168.1.2 null
 
I'm still not able to ping the r2 router, but at least the lldp is working.

Best regards.
