Configuring Route Redistribution Configuration

This screen can be used to configure the RIP Route Redistribution parameters. The
allowable values for each field 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 'Static', 'Connected', 'OSPF' and 'Create'.

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',
and 'OSPF'.

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.
