Segment Routing config
set protocols ospf source-packet-routing node-segment ipv4-index 100x ------ node segment 레이블 설정
set protocols ospf source-packet-routing srgb start-label 800000 -------------------------- 시작 레이블 설정
set protocols ospf source-packet-routing srgb index-range 4000 --------------------------- 인덱스 범위 설정
show ospf neighbor 및 show route summary 명령을 사용하여 OSPF가 제대로 작동하고, 레이블이 있는 OSPF (L-OSPF) 경로가 광고되는지 확인.
inet.3 에 L-OSPF 경로 확인.
inet.3 테이블에 다른 Router loopback 주소가 있으므로 BGP next hop recursive route lookup에 사용가능.
동일한 label 로 swap함. 경로에 있는 모든 라우터가 동일 레이블로 swap한다.
R7 에서 광고받은 경로(10.0.1.0/24)의 protocol next hop 이 192.168.100.7이고 inet.3 테이블 확인.
경로확인 R1 - R2 - R5 - R7
R1에서 TE 설정 ( 경로 R1 - R3 - R4 - R5 -R7 )
