Parameter

Description

Route Map Number

Identifies the route map

Sequence Number

Identifies the sequence within the route map. The numbers need not be consecutive.

Match List Name

Associates an access list with this sequence, as shown in the figure above.

Weight

Alters the weight used to determine the best path. This value replaces the importance
assigned to the route by the weight parameter in the neighbor configuration.

Origin, Set Nexthop,
Set Metric, Set Local
Preference, Set
Atomic Aggregate,
Set Aggregate AS
number, Set AS Path,
AS Path Prepend,
AS Path AS-SET

These parameters modify the path attributes with the same name in the update
message.

STEP SEVEN
The neighbor definition should now be changed again to include the new route map. This is done in the Neighbor
Menu described in step 2.

STEP EIGHT
This last step permits aggregation of networks inside the AS to simplify routing tables. In the example in Figure
12.4, the two networks can be aggregated to form one network with the IP address/Mask of 200.50.50.0/23.
