Chapter 3 Configuring OSPFv2
Configuring Advanced OSPFv2
This example shows how to control LSA flooding with the lsa-group-pacing option:
switch# configure terminal
switch(config)# router ospf 201
switch(config-router)# timers lsa-group-pacing 300
switch(config-router)# copy running-config startup-config
Restarting an OSPFv2 Instance
You can restart an OSPv2 instance. This clears all neighbors for the instance.
To restart an OSPFv2 instance and remove all associated neighbors, use the following command:
Configuring OSPFv2 with Virtualization
You can create multiple VRFs and use the same or multiple OSPFv2 instances in each VRF. You assign
an OSPFv2 interface to a VRF.
Note Configure all other parameters for an interface after you configure the VRF for an interface. Configuring
a VRF for an interface deletes all the configuration for that interface.
BEFORE YOU BEGIN
Ensure that you have enabled the OSPF feature (see the “Enabling the OSPFv2 Feature” section on
page 3-13).
