◆
A designated router (DR) and backup designated router (BDR) are
elected for each OSPF area based on Router Priority. The DR forms an
active adjacency to all other routers in the area to exchange routing
topology information. If for any reason the DR fails, the BDR takes over
this role.
◆
Set the priority to zero to prevent a router from being elected as a DR
or BDR. If set to any value other than zero, the router with the highest
priority will become the DR and the router with the next highest priority
becomes the BDR. If two or more routers are tied with the same
highest priority, the router with the higher ID will be elected.
◆
If a DR already exists for a network segment when this interface comes
up, the new router will accept the current DR regardless of its own
priority. The DR will not change until the next time the election process
is initiated.
◆
Configure router priority for multi-access networks only and not for
point-to-point networks.
