USING THE WEB MANAGEMENT INTERFACE
To enable learning of default RIP routes:
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 RIP in the tree view to expand the list of RIP option links.
4. Click on the Interface link to display the RIP interface table.
5. Click on the Modify button in the row for the port.
6. Select Disable or Enable next to Learn Default.
7. Click the Apply button to save the change to the device's running-config file.
NOTE: To apply the changes to all RIP interfaces, select the Apply To All Ports button instead of the Apply
button.
8. To configure settings for another port, select the port (and slot, if applicable) and go to step 5.
9. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device's flash memory.
Configuring a RIP Neighbor Filter
By default, a Foundry Layer 3 Switch learns RIP routes from all its RIP neighbors. Neighbor filters allow you to
specify the neighbor routers from which the Foundry router can receive RIP routes. Neighbor filters apply globally
to all ports.
USING THE CLI
To configure a RIP neighbor filters, enter a command such as the following:
BigIron(config-rip-router)# neighbor 1 deny any
Syntax: [no] neighbor <filter-num> permit | deny <source-ip-address> | any
This command configures the Layer 3 Switch so that the device does not learn any RIP routes from any RIP
neighbors.
The following commands configure the Layer 3 Switch to learn routes from all neighbors except 192.168.1.170.
Once you define a RIP neighbor filter, the default action changes from learning all routes from all neighbors to
denying all routes from all neighbors except the ones you explicitly permit. Thus, to deny learning from a specific
neighbor but allow all other neighbors, you must add a filter that allows learning from all neighbors. Make sure
you add the filter to permit all neighbors as the last filter (the one with the highest filter number). Otherwise, the
software can match on the permit all filter before a filter that denies a specific neighbor, and learn routes from that
neighbor.
BigIron(config-rip-router)# neighbor 2 deny 192.16.1.170
BigIron(config-rip-router)# neighbor 1024 permit any
USING THE WEB MANAGEMENT INTERFACE
To define a RIP neighbor filter:
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 RIP in the tree view to expand the list of RIP option links.
4. Click on the Neighbor Filter link.
• If the device does not have any RIP neighbor filters, the RIP Neighbor Filter configuration panel is
displayed, as shown in the following example.
