Help for RIP Configuration

Configurable Data

RIP Admin Mode - Select enable or disable from the pulldown menu. If you select enable RIP will be enabled for the switch. The default is disable.
Split Horizon Mode - Select none, simple or poison reverse from the pulldown menu. Split horizon is a technique for avoiding problems caused by including routes in updates sent to the router from which the route was originally learned. The options are:
- None - no special processing for this case.
- Simple - a route will not be included in updates sent to the router from which it was learned.
- Poisoned reverse - a route will be included in updates sent to the router from which it was learned, but the metric will be set to infinity.
The default is simple.
Auto Summary Mode - Select enable or disable from the pulldown menu. If you select enable groups of adjacent routes will be summarized into single entries, in order to reduce the total number of entries The default is enable.
Host Routes Select Mode - Select enable or disable from the pulldown menu. If you select enable the router will be accept host routes. The default is enable.
Default Information Originate - Enable or Disable Default Route Advertise.
Default Metric - Sets a default for the metric of redistributed routes.This field displays the default metric if one has already been set or blank if not configured earlier. The valid values are (1 to 15)

Non-Configurable Data

Global Route Changes - The number of route changes made to the IP Route Database by RIP. This does not include the refresh of a route's age.
Global queries - The number of responses sent to RIP queries from other systems.

Command Buttons

Submit - Send the updated configuration to the switch. Configuration changes take effect immediately. These changes will not be retained across a power cycle unless a save is performed.

Help for RIP Interface Summary

Non-Configurable Data

Slot/Port - The slot and port for which the information is being displayed.
IP Address - The IP Address of the router interface.
Send Version - The RIP version to which RIP control packets sent from the interface conform. The value is one of the following:
- RIP-1 - RIP version 1 packets will be sent using broadcast.
- RIP-1c - RIP version 1 compatibility mode. RIP version 2 formatted packets will be transmitted using broadcast.
- RIP-2 - RIP version 2 packets will be sent using multicast.
- None - RIP control packets will not be transmitted.
The default is RIP-2.
Receive Version - Which RIP version control packets will be accepted by the interface. The value is one of the following:
- RIP-1 - only RIP version 1 formatted packets will be received.
- RIP-2 - only RIP version 2 formatted packets will be received.
- Both - packets will be received in either format.
- None - no RIP control packets will be received.
The default is Both.
RIP Admin Mode - Whether RIP is enabled or disabled on the interface.
Link State - Whether the RIP interface is up or down.

Help For RIP Interface Configuration

Selection Criteria

Slot/Port - Select the interface for which data is to be configured.

Configurable Data

Send Version - Select the version of RIP control packets the interface should send from the pulldown menu. The value is one of the following:
- RIP-1 - send RIP version 1 formatted packets via broadcast.
- RIP-1c - RIP version 1 compatibility mode. Send RIP version 2 formatted packets via broadcast.
- RIP-2 - send RIP version 2 packets using multicast.
- None - no RIP control packets will be sent.
The default is RIP-2.
Receive Version - Select what RIP control packets the interface will accept from the pulldown menu. The value is one of the following:
- RIP-1 - accept only RIP version 1 formatted packets.
- RIP-2 - accept only RIP version 2 formatted packets.
- Both - accept packets in either format.
- None - no RIP control packets will be accepted.
The default is Both.
RIP Admin Mode - Select enable or disable from the pulldown menu. Before you enable RIP version 1 or version 1c on an interface, you must first enable network directed broadcast mode on the corresponding interface. The default value is disable.
Authentication Type - You may select an authentication type other than none by clicking on the 'Configure Authentication' button. You will then see a new screen, where you can select the authentication type from the pulldown menu. The choices are:
- None - This is the initial interface state. If you select this option from the pulldown menu on the second screen you will be returned to the first screen and no authentication protocols will be run.
- Simple
- Encrypt - If you select 'Encrypt' you will be prompted to enter both an authentication key and an authentication ID. Encryption uses the MD5 Message-Digest algorithm. All routers on the network must be configured with the same key and ID.
Authentication Key - Enter the RIP Authentication Key for the specified interface. If you do not choose to use authentication you will not be prompted to enter a key. If you choose 'simple' or 'encrypt' the key may be up to 16 octets long. The key value will only be displayed if you are logged on with Read/Write privileges, otherwise it will be displayed as asterisks.

Non-Configurable Data

IP Address - The IP Address of the router interface.
Link State - Indicates whether the RIP interface is up or down.
Bad Packets Received - The number of RIP response packets received by the RIP process which were subsequently discarded for any reason.
Bad Routes Received - The number of routes, in valid RIP packets, which were ignored for any reason (e.g. unknown address family, or invalid metric).
Updates Sent - The number of triggered RIP updates actually sent on this interface. This explicitly does NOT include full updates sent containing new information.

Command Buttons

Configure Authentication - Display a new screen where you can select the authentication method for the virtual link.
Submit - Send the updated configuration to the switch. Configuration changes take effect immediately. These changes will not be retained across a power cycle unless a save is performed.

Help For RIP Route Redistribution Configuration

This screen can be used to configure the RIP Route Redistribution parameters. The allowable values for each fields are displayed next to the field. If any invalid values are entered, an alert message will be displayed with the list of all the valid values.

Configurable Data

Configured Source - This select box is a dynamic selector and would be populated by only those Source Routes that have already been configured for redistribute by RIP. However, the topmost option in the select box would be "Create", and this allows the user to configure another, among the Available Source Routes. The valid values are
- Create
- Static
- Connected
- OSPF
- BGP
Available Source - This select box is a dynamic selector and would be populated by only those Source Routes that have not previously been configured for redistribution by RIP. This select box would appear only if the user selects "Create" option as Configured Source. The valid values are
- Static
- Connected
- OSPF
- BGP
Metric- Sets the metric value to be used as the metric of redistributed routes. This field displays the metric if the source was pre-configured and can be modified. The valid values are (1 to 15)
Match - One or more of these checkboxes must be selected to set the type of OSPF routes to be redistributed. This field would appear only if Source is "OSPF". This field displays the configured match options if "OSPF" was pre-configured and can be modified.
- Internal - Sets Internal OSPF Routes to be redistributed
- External 1 - Sets External Type 1 OSPF Routes to be redistributed
- External 2 - Sets External Type 2 OSPF Routes to be redistributed
- NSSA-External 1 - Sets NSSA External Type 1 OSPF Routes to be redistributed
- NSSA-External 2 - Sets NSSA External Type 2 OSPF Routes to be redistributed
The default is Internal.
Distribute List - Distribute List - Sets the Access List that filters the routes to be redistributed by the destination protocol. Only permitted routes are redistributed. If this command refers to a non-existent access list, all routes are permitted. The valid values for Access List IDs are (1 to 199). When used for route filtering, the only fields in an access list that get used are
- Source IP Address and netmask
- Destination IP Address and netmask
- Action (permit or deny)
All other fields (source and destination port, precedence, tos, etc.) are ignored.
The source IP address is compared to the destination IP address of the route. The source IP netmask in the access list rule is treated as a wildcard mask, indicating which bits in the source IP address must match the destination address of the route. (Note that a 1 in the mask indicates a "don’t care" in the corresponding address bit.)
When an access list rule includes a destination IP address and netmask (an extended access list), the destination IP address is compared to the network mask of the destination of the route. The destination netmask in the access list serves as a wildcard mask, indicating which bits in the route’s destination mask are significant for the filtering operation.

Command Buttons

Submit - Send the updated configuration to the router. Configuration changes take effect immediately.
Delete - Delete the entry of the Source Route selected as Configured Source from the list of Sources configured for RIP Route Redistribution.
