Fisheye [Enable, Disable]: To increase stability in a mesh, TC
messages should be sent quite frequently. However, the network
would then suffer from the resulting overhead. The idea is to
frequently send TC messages to adjacent nodes, i.e. nodes that
are likely to be involved in routing loops, without flooding the
whole mesh with each sent TC message. The default value is
Enable.
Enable local HNA entry
HNA entry [Enable, Disable]: Hosts in an OLSR routed network
can announce connectivity to external networks using HNA
messages. This function is used to set the IPv4 networks to be
announced by this host.
Security
The function uses this shared secret key for signature generation
and verification.
Security [Enable, Disable]: To enable or disable the security
function.
Security Key [0123456789abcdef]: For nodes to participate in the
OLSR routing domain they need to use the key used by the other
nodes. The key is 128-bits.

192.168.2.15
0.0.0.0/0.0.0.0
Destination: The node that packet is sent to.
Gateway: The route packets via which gateway.
Metric: The 'distance' to the target (usually counted in hops).
ETX: the ETX value for this link, calculated by ETX = 1 / (ILQ x LQ).
Interface: the device interface the packets go through.
Type: HOST means that it's belong to node's routing tables. HNA
means that node can connect to internet via this routing path.
