虚拟路由器冗余 - VRR
VRR 使主机能够与任何冗余交换机通信，而无需通过运行动态路由器协议或路由器冗余协议进行重新配置。冗余交换机响应来自主机的 ARP 请求。交换机以相同的方式响应，但如果一个交换机发生故障，则其他冗余交换机将继续响应。您将 VRR 与 MLAG 一起使用。
当您将多个设备连接到单个逻辑连接（例如 MLAG 绑定）时，请使用 VRR。连接到 MLAG 绑定的设备认为绑定的另一端只有一个设备，并且仅转发一份传输帧的副本。如果此帧的目标是虚拟 MAC 地址，并且您正在运行 VRRP，则该帧可以转到连接到 VRRP 备用设备的链路，该链路不会将该帧转发到正确的目的地。由于虚拟 MAC 在两个 MLAG 设备上都处于活动状态，因此任何一个 MLAG 设备都可以处理它接收到的帧。
您不能在同一交换机上同时配置 VRR 和 VRRP。
下图说明了基本的启用 VRR 的网络配置。
该网络包括三台服务器和两台 Cumulus Linux 交换机。这些交换机使用 MLAG。
- 当每个冗余交换机中的网桥连接时，它们都会接收并回复针对虚拟路由器 IP 地址的 ARP 请求。
- 服务器的每个 ARP 请求都会收到来自每个交换机的回复；这些回复是相同的，接收回复的服务器要么忽略第一个回复之后的回复，要么接受它们并覆盖之前的相同回复。
- VRR 使用默认的 fabric-wide MAC 地址 00:00:5E:00:01:01。如有必要，您可以更改 VRR MAC 地址。
配置交换机
交换机实现互连服务器和冗余交换机的第 2 层网络。要配置交换机，请将具有以下接口的网桥添加到每个交换机
- 每个服务器一个绑定接口或交换机端口接口。对于使用 MLAG 的网络，请使用绑定接口。否则，请使用交换机端口接口。
- 每个对等交换机一个或多个接口。为了适应交换机之间更高的带宽并提供链路冗余，多个对等互连链路通常是绑定接口。VLAN 接口必须同时具有物理接口和虚拟接口的唯一 IP 地址；交换机在启动 ARP 请求时使用该唯一地址。
Cumulus Linux 仅在 SVI 上支持 VRR。您不能在物理接口或虚拟子接口上配置 VRR。
以下示例命令为启用 VRR 的网络创建 VLAN 感知网桥接口。该示例假定您已经配置了一个带有 VLAN 10 的 VLAN 感知网桥，并且 VLAN 10 具有 IP 地址并使用默认的 fabric-wide VRR MAC 地址 00:00:5e:00:01:01。
cumulus@switch:~$ nv set interface vlan10 ip vrr address 10.1.10.1/24
cumulus@switch:~$ nv set interface vlan10 ip vrr state up
cumulus@switch:~$ nv config apply
对 IPv6 地址使用相同的命令；例如
cumulus@switch:~$ nv set interface vlan10 ip vrr address 2001:db8::1/32
cumulus@switch:~$ nv set interface vlan10 ip vrr state up
编辑 /etc/network/interfaces 文件，然后运行 ifreload -a 命令。
cumulus@switch:~$ sudo nano /etc/network/interfaces
...
auto vlan10
iface vlan10
address 10.1.10.2/24
address-virtual 00:00:5e:00:01:01 10.1.10.1/24
vlan-raw-device br_default
vlan-id 10
...
cumulus@switch:~$ sudo ifreload -a
更改 VRR MAC 地址
Cumulus Linux 设置 fabric-wide MAC 地址以确保 VRR 交换机之间的一致性，这在 EVPN 多 fabric 环境中尤其有用。如果您愿意，可以使用一个 NVUE 命令全局更改 VRR MAC 地址。您还可以覆盖特定 VLAN 的全局设置。
要使用一个 NVUE 命令全局设置 VRR MAC 地址，请执行以下操作之一
- 将 fabric-wide VRR MAC 地址设置为 00:00:5E:00:01:00 和 00:00:5E:00:01:FF 之间的保留范围内的值。请务必使用此保留范围内的地址，以防止 MAC 地址与同一桥接网络中的其他接口发生冲突。
- 设置 fabric ID，Cumulus Linux 从中派生 MAC 地址。您可以指定介于 1 到 255 之间的数字。Cumulus Linux 将该数字以十六进制形式添加到 MAC 地址 00:00:5E:00:01:00。例如，如果您指定 255，则 VRR MAC 地址为 00:00:5E:00:01:FF。
默认的 VRR MAC 地址为 00:00:5E:00:01:01，交换机从 fabric ID 设置 1 派生而来。
要在交换机上全局更改 VRR MAC 地址，请运行 nv set system global fabric-mac <mac-address> 命令
cumulus@switch:mgmt:~$ nv set system global fabric-mac 00:00:5E:00:01:FF
cumulus@switch:mgmt:~$ nv config apply
要设置 fabric ID，请运行 nv set system global fabric-id <number> 命令
cumulus@switch:mgmt:~$ nv set system global fabric-id 255
cumulus@switch:mgmt:~$ nv config apply
要覆盖特定 VLAN 的全局设置，请运行 nv set interface <vlan> ip vrr mac-address <mac-address> 命令
cumulus@switch:mgmt:~$ nv set interface vlan10 ip vrr mac-address 00:00:5E:00:01:00
cumulus@switch:mgmt:~$ nv config apply
要手动更改 VRR MAC 地址，请编辑 /etc/network/interfaces 文件，并更新每个 VLAN 的 address-virtual 行中的 MAC 地址。Cumulus Linux 在 /etc/network/interfaces 文件中不提供 fabric ID 选项。
以下示例显示 vlan10、vlan20 和 vlan30
cumulus@switch:mgmt:~$ sudo nano /etc/network/interfaces
...
auto vlan10
iface vlan10
address 10.1.10.5/24
address-virtual 00:00:5E:00:01:FF 10.1.10.1/24
hwaddress 44:38:39:22:01:c1
vrf RED
vlan-raw-device br_default
vlan-id 10
auto vlan20
iface vlan20
address 10.1.20.5/24
address-virtual 00:00:5E:00:01:FF 10.1.20.1/24
hwaddress 44:38:39:22:01:c1
vrf RED
vlan-raw-device br_default
vlan-id 20
auto vlan30
iface vlan30
address 10.1.30.5/24
address-virtual 00:00:5E:00:01:FF 10.1.30.1/24
hwaddress 44:38:39:22:01:c1
vrf BLUE
vlan-raw-device br_default
vlan-id 30
...
确保在两个 MLAG 对等设备上设置相同的 VRR MAC 地址。
带有 VRR 的 EVPN 路由
在 EVPN 路由环境中，如果要在 VLAN 上将多个子网配置为 VRR 地址，则必须使用相同的 VRR MAC 地址配置它们。
以下示例命令在 VLAN 10 上配置 10.1.10.1/24 和 10.1.11.1/24，使用默认的 fabric-wide VRR MAC 地址 00:00:5e:00:01:01。
cumulus@switch:mgmt:~$ nv set interface vlan10 ip vrr address 10.1.10.1/24
cumulus@switch:mgmt:~$ nv set interface vlan10 ip vrr address 10.1.11.1/24
cumulus@switch:mgmt:~$ nv config apply
编辑 /etc/network/interfaces 文件；例如
cumulus@switch:mgmt:~$ sudo nano /etc/network/interfaces
auto vlan10
iface vlan10
address 10.1.10.2/24
address 10.1.11.2/24
address-virtual 00:00:5e:00:01:01 10.1.10.1/24 10.1.11.1/24
hwaddress 44:38:39:22:01:7a
vlan-raw-device br_default
vlan-id 10
...
为了减少收敛期间的 BGP EVPN 处理，NVIDIA 建议您在所有 VLAN 和 VRR 子网中使用相同的 fabric-wide MAC 地址。
配置服务器
每台服务器必须有两个网络接口。交换机将接口配置为运行 LACP 的绑定；服务器还必须使用团队、端口聚合、端口组或运行 LACP 的 EtherChannel 配置这两个接口。使用静态或 DHCP 配置服务器，网关地址是虚拟路由器的 IP 地址；此默认网关地址永远不会更改。
在 active-active 模式下配置服务器和交换机之间的链路，以实现 FHRP。
故障排除
要验证交换机上的配置，请运行 nv show interface 命令
cumulus@leaf01:mgmt:~$ nv show interface

此模拟正在运行 Cumulus Linux 5.11。Cumulus Linux 5.12 模拟即将推出。
该模拟使用 NVUE 命令预配置。
要验证配置，请运行 nv show interface <vlan> ip vrr 命令
cumulus@leaf02:mgmt:~$ nv show interface vlan10 ip vrr
