如何使用iproute2設定bond網路 - Linux

嗨各位大大，我現在有個問題
「如何在Linux中建立bond網路」

我的最終目標是可以建立bond並且讓其可以連上網際網路
我在container中與host都做過了一樣的事情，但是卻得到了一樣的結果
我想使用container可以更容易復現我的結果

1. 環境建立
docker run --cap-add=NET_ADMIN -it ubuntu:20.04
apt update && apt install -y iproute2

2. 建立虛擬網路
# 建立 bond0 網路，並且設定為 backup 模式
ip link add bond0 type bond mode active-backup primary eth0
ip link set eth0 down
# 設定 eth0 為 bond0 的子網路
ip link set eth0 master bond0
# 啟動
ip link set eth0 up
ip link set bond0 up

3. 測試
# 為了避免dns問題，使用ip更為可靠
curl -vv -H 'Host: www.google.com' 142.251.10.94

我也看過了幾篇網路文章，但是照著操作卻無法連上網路
1. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/configuring-network-bonding_configuring-and-managing-networking
2. http://www.uni-koeln.de/~pbogusze/posts/LACP_configuration_using_iproute2.html

目前在猜測是否需要使用 iptable 去設定封包流 （希望不是）

其他輸出:
$ ip a
