Note:
The DR priorities configured by the ospf dr-priority command and the peer
command have different purpose:
z The priority set with the ospf dr-priority command is used for actual DR election.
z The priority set with the peer command is used to indicate if a neighbor has the
right to vote. If you specify the priority to 0 when configuring a neighbor, the local
router will believe that the neighbor has no right to vote and sends no Hello packet
to it. This configuration can reduce the number of Hello packets on the network
during the election of DR and BDR. However, if the local router is already a DR or
BDR, it will send Hello packets to the neighbor whose DR priority is 0 to establish
the neighboring relationship.
4.6 OSPF Route Control
Perform the following configurations to control the advertisement and reception of the
routing information discovered by OSPF and import routing information discovered by
other protocols.
4.6.1 Configuration Prerequisites
Before configuring OSPF route control, perform the following tasks:
z Configuring the network layer addresses of interfaces so that the adjacent nodes
are reachable to each other at the network layer
z Completing basic OSPF configuration
z Configuring filter list to filter routing information
4.6.2 Configuring OSPF Route Summary
The configuration of OSPF route summary includes:
z Configuring ABR route summary,
z Configuring ASBR route summary for imported routes.
