I've tried to lab this and getting unconclusive results ..
question is about Type 5 LSAs, if a router recieves two type 5s and both are same type and metric, which one is preferred?
eg
R1 -----------------R2-----------------------R3
all in area 0. Same ospf costs.
R1 router id = 10.1.99.1
R3 router id = 10.1.99.3
R1 is redistributing 192.168.10.0 /24 , R3 is redistributing same 192.168.10.0 /24
Which LSA does R2 prefer and why ? Im getting R3 being preferred regardless of LSA age -- but then i read somewhere lower R-ID preferred so am confused a bit.
