Utilizing LHG60 with less capacity backup link on different waveband, main and backup lines are switched via OSPF. Problem is when weather going bad and decrease LHG60 link quality it start loosing packets but short OSPF packets still going throught and OSPF did not switch to backup line.
Have idea to add some signal level thresholds point to radion configuration on witch packets will no longer been transmited through radio layer. Let say "Lower Thrashold Level - LTL" and "Higher Threshold Level - HTL" could be defined in radio management.
Let say my experiance is on signal 35 the packetloss is 1% but on signal 30 is 10%. Than LTL could be signal 35 but HTL could be signal 40. When signal decreasing and reach LTL, radio link stop forwarding packets and OSPF switch to backup. When signal increasing and reach HTL, radio start packets forwarding again. The difference between HTL and LTL is to avoid oscilating beteen two states when signal floating about the limit.
It could stop only OSPF packets (protocol 89) passthrough on LTL reach, but have no idea if there is a internal mechanism to identify protocol number.
