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 )

 - 172.16.1.3 은 direct connected neighbor IP

inet.3 에서  label stack 확인가능.

경로확인 R1 - R3 - R4 - R5 - R7

위와 같은 웹로그인 화면에서 아무리 로그인 시도를 해도 반응이 없을때 

아래 3가지 방법을 시도해보세요

1. eve-ng 콘솔 또는 ssh 접속후 아래 명령어 입력하여 권한수정

   root@eve-ng:~# /opt/unetlab/wrappers/unl_wrapper -a fixpermissions

2. "df -h"를 사용하여 기존 HDD 용량을 확인하고. 가득 차면 VM Ware에서 새 SCSI 카드 드라이브를 만들어 HDD를 추가

3. eve-ng 콘솔 또는 ssh 접속후 아래 명령어 입력하여 SQL 데이터페이스를 수정

   root@eve-ng:~# /opt/unetlab/wrappers/unl_wrapper -a restoredb
