OSPF C ONFIGURE C OMMANDS
Use OSPF configure commands to configure all OSPF routing parameters.
NOTE: See the command configure interface loopback in the Command Reference Guide: Domestic
Products for important information about loopback interfaces.
When configuring OSPF, keep the following in mind:
n When you enable OSPF on bundles, make sure that both ends of the bundle are either
“numbered” or “unnumbered.” If there is a mismatch, even though the adjacency will come up,
route reachability issues may develop.
n When the IP address is specified for a bundle and you later want to change the network type on
that bundle to “broadcast,” you must also specify the type parameter for the bundle IP address.
To do this, you must delete the bundle’s assigned IP address and reassign the IP address with the
type broadcast parameter. For example:
Alcatel /configure/interface/bundle wan1> no ip address 2.2.2.2 24
Alcatel/configure/interface/bundle wan1> ip address 2.2.2.2 24 type broadcast
n Adjacencies will not form if hello_interval, dead_interval, or area_type mismatches are present.
