In case of point to point networks when link goes down, the attached router will come to know about the state change and will immediately flood the link state update packets. So in this case it takes less time for the state change to get propagated.
R1 R2 R3 R4 | | | | | | | |
------------------ Multiaccess network
How does this work in case of broadcast networks. Support router R1,R2,R3 and R4 are part of broadcast networks and R1,R2 are DR and BDR respectively. If the link connecting R3 to broadcast network is down how will the DR come to know about this state change and how long does it take to come to know this change.
As I understand it is possible to come to know about this state change using hello packet.Does DR wait for DeadInterval and then declare that the state change. In that case it is long interval.
Any help on this...
