ROSE protocole is extensively used for level 2 or level 3 networking 
packet AX25 frames through neighbours and digipeaters stations in order 
to exchange data or messages by radio or Internet links.

nodes and routes are most often managed by FPAC suite of applications.

fpad sets up local nodes and adjacent neighbours using fpac.conf, 
fpac.nodes and fpac.routes configuration files.

Then at any time it is possible to add or delete rose nodes from the 
list of previously defined nodes to help routing and connections using 
ax25tools application rsparms:

# rsparms  -nodes list
2080175520/0010 -> ax0    F6BVP-9
2080175526/0010 -> ax0    F6BVP-11
2080835201/0010 -> ???    RSLOOP-0

# rsparms  -nodes add 2080444501/0 axudp F3KT-11 F6BVP-9

# rsparms  -nodes list
2080175520/0010 -> ax0    F6BVP-9
2080175526/0010 -> ax0    F6BVP-11
2080835201/0010 -> ???    RSLOOP-0
          */0000 -> ax0    F3KT-11   via F6BVP-9

# rsparms  -nodes d 2080444501/0 axudp F3KT-11 F6BVP-9

# rsparms  -nodes list
2080175520/0010 -> ax0    F6BVP-9
2080175526/0010 -> ax0    F6BVP-11
2080835201/0010 -> ???    RSLOOP-0

Up to now no issues have been encountered during add or delete nodes 
process.
