OSPF Name Aggregation
Using OSPF Name Aggregation
Name Limitations
Each OSPF name in the network database consumes a small amount of IOP/IOM,
ULC, BIO, and CP/SP/NP memory. Because the network has a fixed amount of
memory for all Lucent switch cards, it is not possible to provision unlimited OSPF
names in the network. However, you can use OSPF name aggregation to maintain a
balance between the maximum number of OSPF names the network can support and
the total amount of memory available for other required switch functions.
Using OSPF Name Aggregation
This section provides a sample network configuration, summarizes the drawbacks of
the typical approach to address provisioning, and describes two ways of using OSPF
name aggregation to provision the sample network prefixes and addresses more
efficiently.
Sample Network Addressing Scenario
The network scenario in Figure G-1 displays sample configuration and addressing
information for Switches 1, 2, and 3. These switches can represent any combination of
B-STDX, CBX, or GX switches.
Figure G-1. Sample Network Addressing Scenario
Note – See the current switch Software Release Notice (SRN) for recommended
OSPF name limitations for each card and switch, and for the entire network. These
limitations can change with each switch software release.
