6.4. 경로 광고 설정 예시

클러스터 관리자는 클러스터에 대한 다음 예제 경로 광고 설정을 구성할 수 있습니다. 이 구성은 경로 광고를 구성하는 방법을 보여주는 샘플입니다.

6.4.1. 샘플 경로 광고 설정
링크 복사

클러스터 관리자는 클러스터에 대한 BGP(Border Gateway Protocol) 라우팅 지원을 활성화할 수 있습니다. 이 구성은 경로 광고를 구성하는 방법을 보여주는 샘플입니다. 이 구성에서는 전체 메시 설정 대신 경로 반사를 사용합니다.

참고

BGP 라우팅은 베어메탈 인프라에서만 지원됩니다.

사전 요구 사항

OpenShift CLI(oc)를 설치합니다.
클러스터 관리자 권한이 있는 사용자로 클러스터에 로그인했습니다.
클러스터는 베어메탈 인프라에 설치됩니다.
FRR 데몬 컨테이너를 실행할 클러스터에 액세스할 수 있는 베어 메탈 시스템이 있습니다.

다음 명령을 실행하여 RouteAdvertisements 기능 게이트가 활성화되었는지 확인하세요.
```
oc get featuregate -oyaml | grep -i routeadvertisement
```
```
$ oc get featuregate -oyaml | grep -i routeadvertisement

다음 내용을 포함하는 daemons 라는 파일을 만듭니다.

데몬 구성 파일 예

This file tells the frr package which daemons to start.
Sample configurations for these daemons can be found in
/usr/share/doc/frr/examples/.
ATTENTION:
When activating a daemon for the first time, a config file, even if it is
empty, has to be present *and* be owned by the user and group "frr", else
the daemon will not be started by /etc/init.d/frr. The permissions should
be u=rw,g=r,o=.
When using "vtysh" such a config file is also needed. It should be owned by
group "frrvty" and set to ug=rw,o= though. Check /etc/pam.d/frr, too.
The watchfrr and zebra daemons are always started.
If this option is set the /etc/init.d/frr script automatically loads
the config via "vtysh -b" when the servers are started.
Check /etc/pam.d/frr if you intend to use "vtysh"!
configuration profile
This is the maximum number of FD's that will be available.
Upon startup this is read by the control files and ulimit
is called. Uncomment and use a reasonable value for your
setup if you are expecting a large number of peers in
say BGP.
The list of daemons to watch is automatically generated by the init script.
for debugging purposes, you can specify a "wrap" command to start instead
of starting the daemon directly, e.g. to use valgrind on ospfd:
  ospfd_wrap="/usr/bin/valgrind"
or you can use "all_wrap" for all daemons, e.g. to use perf record:
  all_wrap="/usr/bin/perf record --call-graph -"
the normal daemon command is added to this at the end.
