As far as I know, the priority keyword in neighbor statement means the neighbor
's priority. It is recommended to set on NBMA networks to influence DR election
.
For example if the the router has config like
int s 0
encapsulation frame-relay ietf
ip address 172.16.100.1 255.255.255.252
ip ospf priority 0
router ospf 1
neighbor 172.16.100.2 priority 100
Then this router does not try to be DR or BDR but consider the neighbor as DR,
this simplifies and determines the DR/BDR selection.
It works this way, I have tried this.
In fact, I don't know if the priority in neighbor statement takes precedence ov
er the priority in hello packets.
