I have question regarding how OSPF behave
in selecting route
A--R0--R1----R2----R3---R4
\ /
----------
Where R1 is connected back to back with R2
using Serial 0
and R1 is connected back to back with R3 using
Serial 1
A is host connected to R0 and is in Area 0
Link R0 to R1 , OSPF Area 0
Link R1 to R2 , OSPF Area 1
Link R2 to R3, OSPF Area 2
Link R3 to R4, OSPF Area 2
Link R1 to R3, OSPF Area 3
There is virtual link to between R0-R1 to R2-R3
using Area 1 as transit area
When R4 try to reach A, which Route R4 will use
Is R4-R3-R2(Virtual Link)-R1-R0-A or
R4-R3-R1-A ?
Can somebody explain to me how route selection
in ospf works in this case ?
Thanks in advance
