ipmp 설정 문제..

[몸이]

ipmp를 active - active로 구성 할려구 합니다

e1000g2 -> 192.168.0.2      e1000g2:1 -> 192.168.0.12

e1000g3 -> 192.168.0.3      e1000g3:1 -> 192.168.0.13 이렇게 아이피를 설정 했습니다

ifconfig e1000g2 plumb 192.168.0.2 group MNIC up

ifconfig e1000g2 addif 192.168.0.12 deprecated -failover up

bash-3.00# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 inde
 1
        inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 192.168.0.1 netmask ffffff00 broadcast 192.168.0.255
        ether 0:14:4f:e:eb:62
e1000g2: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 5
        inet 192.168.0.2 netmask ffffff00 broadcast 192.168.0.255
        groupname MNIC
        ether 0:14:4f:e:eb:64
e1000g2:1: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILO
ER> mtu 1500 index 5
        inet 192.168.0.12 netmask ffffff00 broadcast 192.168.0.255

bash-3.00# ifconfig e1000g3 plumb 192.168.0.3 group MNIC up
bash-3.00# ifconfig e1000g3 addif 192.168.0.13 deprecated -failover up

두번째 가상 아이피를 설정 해주면 밑에 처럼 아이피가 바뀝니다

랜선은 뽑지 않았구요

bash-3.00# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 inde
 1
        inet 127.0.0.1 netmask ff000000

        inet 192.168.0.2 netmask ffffff00 broadcast 192.168.0.255
e1000g3:2: flags=19040803<UP,BROADCAST,MULTICAST,DEPRECATED,IPv4,NOFAILOVER,FAI
ED> mtu 1500 index 6
        inet 192.168.0.13 netmask ffffff00 broadcast 192.168.0.255

위와 같은 현상은 어떤 문제가 있는 건가요?? 답변 부탁드려요.

=========================================================================================

/etc/hosts , /etc/hostname.e1000g2 , /etc/hostname.e1000g3 에 등록을 하고

재부팅을 시켰더니 제대루 아이피 나오기는 합니다 근데.. ping을 e1000g2 에 하고

e1000g2 쪽 랜선을 뽑아버리고 ifcofnig -a 를 해보면 아이피에 변화가 없습니다;;

도대체 머가 문제 인지 모르겠습니다;;;  답변 부탁드립니다.

설정하는 명령어 상에서는 문제가 보이지 않고요.... 처음 설정 했을때 부터 ifconfig 출력 화면에 보면 e1000g3, e1000g3:1 설정하자 마자 .... Failed 플래그가 보이는 것으로 보아.... 바로 Fail over 기능이 동작한것 같습니다. 제가 정상적인 절차 대로 작업한 내용 한번 올릴께요. ^^

[진짜 메미넴™]

아무리 라우터가 중요하다고 말씀드렸지만.... 너무 하시다는 -_-;;;;;

[몸이]

ㅋㅋ 돼는듯 했으나.. 또 안되네여 =ㅅ =;;;

[백승찬]

ㅋㅋㅋㅋ.... 이런... 해결된줄 알았는데... ^^

[몸이]

강사님 failback 기능은 따로 설정을 해주어야하나요? /etc/default/mpathd 여기에서 failback=yes 로만 해주면 대는걸루 알고 있는데 ㅎㅎ;

[백승찬]

아니요... IPMP는 failover, failback 기능이 자동입니다. 따로 설정하지 않습니다.

[백승찬]

IPMP는 기본설정 쓰시면 자동입니다.
