29-104
Usage Guide:
A route-map may consist of several nodes each of which is a check unit. The check sequence
among nodes is identified by sequence-number. “permit” means the node filter will be passed if all
match subs are obtained by current route and then further all the set sub of this node will be
executed without entering the check in the next node; if the match subs can not be met, the proceed
to the check in next node. Relation among different node should be “or”, namely one node check
passed then the route filter is passed when the switch checks each node in turn in the route-map.
Attentions should be paid on that at least one node match mode should be “permit” when more than
one node is defined. When a route-map is used for filtering routing messages, if certain routing
message can not pass any node check, then it is considered denied by the route-map. If all nodes in
the route-map are set to deny mode, then all routing message should not be able to pass that
route-map.
Example:
Switch#config terminal
Switch(config)#route-map r1 permit 5
Switch(config-route-map)#match as-path 60
Switch(config-route-map)#set weight 30

no set aggregator as [ ]
Function:

Command Mode:
route-map mode

To use this command, one match clause should at first be defined.
