Configuring OSPF

Dynamic OSPF memory
Virtual ADX dynamically allocates memory for Link State Advertisements (LSAs) and other OSPF
data structures. So long as the Layer 3 Switch has free (unallocated) dynamic memory, OSPF can
use the memory.
Configuring OSPF
To begin using OSPF on the router, perform the steps outlined below.
1. Enable OSPF on the router.
2. Assign the areas to which the router will be attached.
3. Assign individual interfaces to the OSPF areas.
4. Define redistribution filters, if desired.
5. Enable redistribution, if you defined redistribution filters.
6. Modify default global and port parameters as required.
7. Modify OSPF standard compliance, if desired.
NOTE
OSPF is automatically enabled without a system reset.
Configuration rules
Consider the following:
• If a router is to operate as an ASBR, you must enable the ASBR capability at the system level.
• Redistribution must be enabled on routers configured to operate as ASBRs.
• All router ports must be assigned to one of the defined areas on an OSPF router. When a port is
assigned to an area, all corresponding subnets on that port are automatically included in the
assignment.
OSPF parameters
You can modify or set the following global and interface OSPF parameters:
Global parameters:
• Modify OSPF standard compliance setting.
• Assign an area.
• Define an area range.
• Define the area virtual link.
• Set global default metric for OSPF.
• Change the reference bandwidth for the default cost of OSPF interfaces.
• Disable or re-enable load sharing.
