Usage Guideline DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide This command is to set the route-preference for BGP route. BGP route contains two types one is IBGP and the other is EBGP. When two or more route protocols have learned one same route, the route-preference will be used to decide which one should be added into IP route table. Of course, for one route the smaller the routepreference, the better the route is. Users can verify the settings by entering the show ip route-preference command in Privileged mode. Example This example shows how to configure the iBGP route-preference for autonomous system 200. DXS-3600-32S#configure terminal DXS-3600-32S(config)#router bgp 200 DXS-3600-32S(config-router)#route-preference ibgp 15 DXS-3600-32S(config-router)# 7-66 router bgp This command is used to enable (configure) the BGP routing process. Use the no form of this command to remove a BGP routing process. router bgp AS-NUMBER no router bgp AS-NUMBER Parameters AS-NUMBER Specifies the number of an autonomous system that identifies the router to other BGP routers. The range for 2-byte numbers is 1 to 65535. The range for 4-byte numbers is 1 to 4294967295. Default Command Mode Command Default Level Usage Guideline No BGP routing process is enabled by default. Global Configuration Mode. Level: 8. (EI Mode Only Command) Each public autonomous system that directly connects to the Internet is assigned a unique number that identifies both the BGP routing process and the autonomous system (a number from 1 to 64511). Private autonomous system numbers are in the range from 64512 to 65534 (65535 is reserved for special use). The AS Number size is defined as 2 bytes in RFC1771 and RFC4271. But the AS Number can be expanded to 4 bytes to support much AS number.[RFC4893] To support 4-byte AS number, the AS number range is supported from 1 to 4294967295. Private autonomous system numbers can be used for internal routing domains but must be translated for traffic that is routed out to the Internet. BGP should not be configured to advertise private autonomous system numbers to external networks. Use this command to enter router configuration mode for the specified routing process. Example This example shows how to configure a BGP process for autonomous system 200. DXS-3600-32S#configure terminal DXS-3600-32S(config)#router bgp 200 DXS-3600-32S(config-router)# 115
