네트워크에서 BGP 불평등 비용로드 균형 조정 기능을 구현하려고합니다. 시스코 매뉴얼에 따르면 (긴 : http://www.cisco.com/c/en/us/td/docs/ios/12_2s/feature/guide/fsbgplb.html , 짧게 : https://ccieblog.co.uk / bgp / bgp-unequal-load-cost-sharing ) 나는 그러한 순 토폴로지를 구축했습니다.
R1- 나가는 트래픽에 대한로드 밸런싱을 구현하려는 라우터. 이름 nat이있는 VRF 테이블 이 사용됩니다.
R2-R4- quagga를 실행하는 NAT 서버, eBGP를 통해 R1 과 공유 되는 R5에 대한 기본 경로 .
R1 IOS 버전 : 12.2 (33) SXJ4 (s72033-adventerprisek9_wan-mz.122-33.SXJ4.bin)
R2 구성 ( R3 R4 전용 router-id와 vlan이 다름)
결과적으로 R1 에 동일한 공유 수-1/1 (1 : 1 : 1)의 3 가지 기본 경로가 있습니다. 그러나 비율 1 : 2 : 3이 연장되었습니다.

내가 무엇을 잘못하고 있지? 매뉴얼에 따르면, 다른 dmzlink bw값은 다른 부하 분배 비율을 유발해야하지만 실제로는 그렇지 않습니다!

neighbor dmzlink-bw는 (구성에 표시된) 이웃에게만 대역폭을 알리는 기능과 bgp dmzlink-bw, 비례로드 밸런싱을 가능하게합니다 (그리고 구성에 누락 된 것 같습니다). bgp dmzlink-bw실행중인 구성 에 넣을 수 있습니까?
bandwidth 50000'인터페이스 Vlan3228'에 대해 실행중인 R1 구성이 누락 되었습니까? 'sh ip bgp <IP of R5>'의 출력도 첨부 해 주시겠습니까?
