USING THE WEB MANAGEMENT INTERFACE
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Click on the plus sign next to Configure in the tree view to expand the list of configuration options.
3. Click on the plus sign next to BGP in the tree view to expand the list of BGP option links.
4. Click on the General link to display the BGP configuration panel, shown in Figure 19.2 on page 19-8.
5. Change the number in the Maximum Routes field. The maximum number you can enter depends on the
device you are configuring. See “Memory Considerations” on page 19-9 for the maximum for your device.
6. Click the Apply button to apply the changes to the device’s running-config file.
7. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change

configuration change into effect.
Changing the Maximum Number of Route-Attribute Entries
The BGP4 route table lists the route attributes associated with each route in the table. These attributes include
the following:
• IP address of the next hop router
• Metric
• Local Preference
• Origin
• Communities
• and others
A collection of these attributes is called a route-attributes entry . Each route-attributes entry is a unique set of
values for these attributes. For example, the following set of attribute values is a route-attributes entry:
Next Hop :192.168.11.1 Metric :0 Origin:IGP
Originator:0.0.0.0 Cluster List:None
Aggregator:AS Number :0 Router-ID:0.0.0.0 Atomic:FALSE
Local Pref:100 Communities:Internet
A route-attribute entry can be used by one or more routes. For example, if the first and second routes listed in the
BGP4 route table use exactly the same set of attribute values, the routes both would use a single route-attributes
entry. If any of the attributes differs for the two routes, each route would use a separate route-attributes entry.
See “Displaying BGP4 Route-Attribute Entries” on page 19-114 for a description of the route-attribute fields shown
in the example above.
You can change the maximum number of route-attribute entries the router can contain using either of the following
methods.
USING THE CLI
To change the maximum number of route-attribute entries to 2500, enter the following command:
NetIron(config-bgp-router)# max-attribute-entries 2500
NetIron(config-bgp-router)# end
NetIron# reload
Syntax: max-attribute-entries <num>
