MetalLBとRTX1300によるBGPmode接続編

前置き

一応動いてるけど、ほんとにいいのこれで？というのがとても不安
というか経路情報をルータに送り込めてなくね…ということでip route書いてます…
けどstatic route書くとちゃんとルータ配下のPCからアクセスできるんよね…
なので一応OKかなと…

FRRモードのMetalLB

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.14.5/config/manifests/metallb-frr.yaml

RTX1300側のconfig

ip route 192.168.101.0/24 gateway 192.168.100.150
bgp use on
bgp autonomous-system 64512
bgp neighbor 2 64513 192.168.100.150 ignore-capability=on
bgp router id 192.168.100.1
