Command Usage
◆
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.
Example
Console(config)#interface vlan 1
Console(config-if)#ipv6 ospf priority 5
Console(config-if)#
ipv6 ospf
