Cisco Nexus 3548 Switch NX-OS Unicast Routing Command Reference
OL-27852-01
Chapter Unicast Routing Commands
set origin
set origin
To set the Border Gateway Protocol (BGP) origin code, use the set origin command. To delete the entry,
use the no form of this command.
set origin {egp as-num [:as-num] | igp | incomplete}
no set origin
Syntax Description
Command Default Default origin, based on route in main IP routing table.
Command Modes Route-map configuration mode
Command History
Usage Guidelines You must have a match clause (even if it points to a “permit everything” list) if you want to set tags.
Use the route-map global configuration command, and the match and set route-map configuration
commands, to define the conditions for redistributing routes from one routing protocol into another. Each
route-map command has a list of match and set commands associated with it. The match commands
specify the match criteria—the conditions under which redistribution is allowed for the current
route-map command. The set commands specify the set actions—the particular redistribution actions
to perform if the criteria enforced by the match commands are met. The no route-map command deletes
the route map.
The set route-map configuration commands specify the redistribution set actions to be performed when
all of the match criteria of a route map are met. When all match criteria are met, all set actions are
performed.
This command requires the LAN Enterprise Services license.
Examples This example shows how to set the origin of routes that pass the route map to IGP:
switch# configure terminal
switch(config)# route-map set_origin
switch(config-route-map)# match as-path 10
switch(config-route-map)# set origin igp
switch(config-route-map)#
egp as-num Specifies the autonomous system (AS) number for a remote exterior
gateway protocol (EGP) system. You can specify the AS number as a 2-byte
integer or a 4-byte integer in aa:nn format. The range is from 1 to 65535.
igp Specifies a local interior gateway protocol (IGP) system.
incomplete Specifies an unknown heritage.
Release Modification
5.0(3)A1(1) This command was introduced.
