Chapter 1. Commands for Routing Policy 17

 no set metric [< metric_val>]

 Function: Configure the metric value of the route. The “no set metric [< metric_val>]”

command deletes the configuration.

 Parameter: <metric_val > is the metric value, ranging between 1～4294967295.

 Command Mode: route-map mode

 Usage Guide: The metric value only affects the path option from external neighbors to

local AS. The less the metric value is the higher is the priority. Under normal

circumstances only the path metric value of the neighbors of the same AS will be

compared. To extend the comparison to the metric values of different neighbor path,

the bgp always-compare-med command should be configured. To use this command,

one match clause should at first be defined.

 Example:

 Switch#config terminal

 Switch(config)#route-map r1 permit 5

 Switch(config-route-map)#set metric 60

1.24 set metric-type

 Command: set metric-type <type-1 | type-2>

 no set metric-type [<type-1 | type-2>]

 Function: Configure the metric type of the OSPF routing message. The “no set metric-

type [<type-1 | type-2>]” command deletes this configuration.

 Parameter: type-1 means matches the OSPF type 1 external route; type-2 means

matches the OSPF type 2 external route.

 Command Mode: route-map mode

 Usage Guide: To use this command, one match clause should at first be defined.

 Example:

 Switch#config terminal

 Switch(config)#route-map r1 permit 5

 Switch(config-route-map)#set metric-type type-1

1.25 set origin

 Command: set origin <egp | igp | incomplete >

 no set origin [<egp | igp | incomplete >]

 Function: Configure the origin code of the BGP routing message. The “no set origin

[<egp | igp | incomplete >]” command deletes this configuration.

 Parameter: egp means the route is learnt from the external gateway protocols, igp

means the route is learnt from the internal gateway protocols, incomplete means the

route origin is uncertain.

 Command Mode: route-map mode

 Usage Guide: To use this command, one match clause should at first be defined.
