本文实验如何通过ovn的分布式网关端口将ovn网络连接到外部网络。
分布式网关端口是一个逻辑路由器端口，只不过它需要绑定到指定节点上(一个或者多个节点)。注意和网关路由器的区别，网关路由器是绑定到指定节点(只能绑定到一个节点)的逻辑路由器，而分布式网关端口只是正常逻辑路由器上的一个端口，只不过需要绑定到某些节点。
下图是ovn-architecture中分布式网关端口的逻辑拓扑，相比较网关路由器简化不少。

设置分布式网关端口，可参考ovn-nb的Distributed Gateway Ports部分，有两种方式，可通过设置Logical_Router_Port表的如下两个参数实现

可以设置多个chassis，并指定chassis的优先级，只有优先级最高的chassis工作，其他chassis作为备份，chassis之间使用bfd检测是否存活。
对应的命令如下
//设置 Distributed Gateway Ports 的方式之一：
ovn-nbctl ha-chassis-group-add ha1
ovn-nbctl ha-chassis-group-add-chassis ha1 master 1
ovn-nbctl ha-chassis-group-add-chassis ha1 node1 2
//465efd10-c0e0-4966-be32-a20b213a2dbc 为 ha1 的uuid，可通过 ovn-nbctl ha-chassis-group-list 查看
ovn-nbctl set Logical_Router_Port lr1-lslocal ha_chassis_group=465efd10-c0e0-4966-be32-a20b213a2dbc
//设置 Distributed Gateway Ports 的方式之二：
ovn-nbctl lrp-set-gateway-chassis lr1-lslocal master 1
ovn-nbctl lrp-set-gateway-chassis lr1-lslocal node1 2

首先创建图中lr1及其上面部分的组件
###创建两个交换机和一个路由器
//创建两个虚拟交换机 ls1 和 ls2
ovn-nbctl ls-add ls1
ovn-nbctl ls-add ls2
//创建一个虚拟路由器 lr1
ovn-nbctl lr-add lr1
//在虚拟路由器 lr1 上添加端口，用来连接虚拟交换机 ls1
ovn-nbctl lrp-add lr1 lr1-ls1 00:00:00:00:00:01 10.10.10.1/24
//在虚拟交换机 ls1 上添加端口，用来连接虚拟路由器 lr1
ovn-nbctl lsp-add ls1 ls1-lr1
//端口类型必须为 router
ovn-nbctl lsp-set-type ls1-lr1 router
//设置地址，必须和 lr1-ls1 的一致
ovn-nbctl lsp-set-addresses ls1-lr1 00:00:00:00:00:01
//指定 router-port
ovn-nbctl lsp-set-options ls1-lr1 router-port=lr1-ls1
//在虚拟路由器 lr1 上添加端口，用来连接虚拟交换机 ls2
ovn-nbctl lrp-add lr1 lr1-ls2 00:00:00:00:00:02 10.10.20.1/24
//在虚拟交换机 ls2 上添加端口，用来连接虚拟路由器 lr1
ovn-nbctl lsp-add ls2 ls2-lr1
//端口类型必须为 router
ovn-nbctl lsp-set-type ls2-lr1 router
//设置地址，必须和 lr1-ls2 的一致
ovn-nbctl lsp-set-addresses ls2-lr1 00:00:00:00:00:02
//指定 router-port
ovn-nbctl lsp-set-options ls2-lr1 router-port=lr1-ls2
###在交换机上添加vm接口
//在虚拟交换机 ls1 上添加两个端口，指定 mac 和 ip(10.10.10.0/24网段)，用来连接vm
ovn-nbctl lsp-add ls1 ls1-vm1
ovn-nbctl lsp-set-addresses ls1-vm1 "00:00:00:00:00:03 10.10.10.2"
ovn-nbctl lsp-set-port-security ls1-vm1 "00:00:00:00:00:03 10.10.10.2"
ovn-nbctl lsp-add ls1 ls1-vm2
ovn-nbctl lsp-set-addresses ls1-vm2 "00:00:00:00:00:04 10.10.10.3"
ovn-nbctl lsp-set-port-security ls1-vm2 "00:00:00:00:00:04 10.10.10.3"
//在虚拟交换机 ls2 上添加两个端口，指定 mac 和 ip(10.10.20.0/24网段)，用来连接vm
ovn-nbctl lsp-add ls2 ls2-vm1
ovn-nbctl lsp-set-addresses ls2-vm1 "00:00:00:00:00:03 10.10.20.2"
ovn-nbctl lsp-set-port-security ls2-vm1 "00:00:00:00:00:03 10.10.20.2"
ovn-nbctl lsp-add ls2 ls2-vm2
ovn-nbctl lsp-set-addresses ls2-vm2 "00:00:00:00:00:04 10.10.20.3"
ovn-nbctl lsp-set-port-security ls2-vm2 "00:00:00:00:00:04 10.10.20.3"
###创建四个vm
//在 master 节点上，创建两个namespace，用来模拟两个vm，使用 "iface-id" 指定
//这两个vm属于 ls1
ip netns add vm1
ovs-vsctl add-port br-int vm1 -- set interface vm1 type=internal
ip link set vm1 netns vm1
ip netns exec vm1 ip link set vm1 address 00:00:00:00:00:03
ip netns exec vm1 ip addr add 10.10.10.2/24 dev vm1
ip netns exec vm1 ip link set vm1 up
ip netns exec vm1 ip route add default via 10.10.10.1 dev vm1
ovs-vsctl set Interface vm1 external_ids:iface-id=ls1-vm1
ip netns add vm2
ovs-vsctl add-port br-int vm2 -- set interface vm2 type=internal
ip link set vm2 netns vm2
ip netns exec vm2 ip link set vm2 address 00:00:00:00:00:04
ip netns exec vm2 ip addr add 10.10.10.3/24 dev vm2
ip netns exec vm2 ip link set vm2 up
ip netns exec vm2 ip route add default via 10.10.10.1 dev vm2
ovs-vsctl set Interface vm2 external_ids:iface-id=ls1-vm2
//在 node1 节点上，创建两个namespace，用来模拟两个vm，使用 "iface-id" 指定这两个vm属于 ls2
ip netns add vm1
ovs-vsctl add-port br-int vm1 -- set interface vm1 type=internal
ip link set vm1 netns vm1
ip netns exec vm1 ip link set vm1 address 00:00:00:00:00:03

ip netns exec vm1 ip link set vm1 up
ip netns exec vm1 ip route add default via 10.10.20.1 dev vm1
ovs-vsctl set Interface vm1 external_ids:iface-id=ls2-vm1
ip netns add vm2
ovs-vsctl add-port br-int vm2 -- set interface vm2 type=internal
ip link set vm2 netns vm2
ip netns exec vm2 ip link set vm2 address 00:00:00:00:00:04
ip netns exec vm2 ip addr add 10.10.20.3/24 dev vm2
ip netns exec vm2 ip link set vm2 up
ip netns exec vm2 ip route add default via 10.10.20.1 dev vm2
ovs-vsctl set Interface vm2 external_ids:iface-id=ls2-vm2
//在lr1上添加静态路由
ovn-nbctl lr-route-add lr1 "0.0.0.0/0" 10.10.30.2
开始创建分布式网关端口相关组件
//设置分布式路由端口
ovn-nbctl lrp-add lr1 lr1-lslocal 00:00:00:00:00:05 10.10.40.1/24
//设置 Distributed Gateway Ports 的方式之一：

//添加逻辑交换机，用于连接外部网络
ovn-nbctl ls-add lslocal
ovn-nbctl lsp-add lslocal lslocal-lr1
ovn-nbctl lsp-set-type lslocal-lr1 router
ovn-nbctl lsp-set-addresses lslocal-lr1 00:00:00:00:00:05

//只有指定的gateway-chassis上需要执行下面命令，本实验中master和node1都被指定成gateway-chassis
//在master节点上执行
ovs-vsctl add-br br-ens8
ovs-vsctl add-port br-ens8 ens8
ovs-vsctl set Open_vSwitch . external-ids:ovn-bridge-mappings=externalnet:br-ens8
ip link set dev br-ens8 up
ip addr add 10.10.40.2/24 dev br-ens8
//在node1节点上执行
ovs-vsctl add-br br-ens8
ovs-vsctl add-port br-ens8 ens8
ovs-vsctl set Open_vSwitch . external-ids:ovn-bridge-mappings=externalnet:br-ens8
ip link set dev br-ens8 up
ip addr add 10.10.40.3/24 dev br-ens8
//在lr1上添加nat表项
ovn-nbctl -- --id=@nat create nat type="snat" logical_ip=10.10.10.0/24 \
external_ip=10.10.40.1 -- add logical_router lr1 nat @nat
创建出的物理拓扑

虽然每个节点上都有patch口连接外部网络，但是只有优先级高的才能生效。比如master的优先级高，那node1上的vm想要访问外部网络，还是需要先将报文通过geneve隧道发送到master，再经过master上的patch访问到外部网络。
