防火墙 BFD配置

在H3C设备上，BFD（Bidirectional Forwarding Detection）和静态路由的配置命令与华为设备有一些不同。以下是将你提供的华为命令翻译成H3C命令的示例：

### 华为命令
```sh
bfd LJDX_CXINAN bind peer-ip 192.168.31.10 vpn-instance ChinaMobile_CXINAN interface GigabitEthernet3/0/3.2040 source-ip 192.168.31.9 auto

ip route-static vpn-instance ChinaMobile_CXINAN 10.88.31.8 255.255.255.248 GigabitEthernet3/0/3.2040 192.168.31.10 track bfd-session LJDX_CXINAN
```

### H3C命令

#### 1. 配置BFD会话
在H3C设备中，BFD会话的配置命令如下：

```sh
<H3C> system-view
[H3C] bfd
[H3C-bfd] discriminator local 100
[H3C-bfd] discriminator remote 101
[H3C-bfd] commit
[H3C-bfd] quit

[H3C] bfd session init-mode active
[H3C] bfd session lsp-trigger enable
[H3C] bfd session vrf ChinaMobile_CXINAN
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] peer-ip 192.168.31.10
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] interface GigabitEthernet 3/0/3.2040
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] source-ip 192.168.31.9
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] discriminator local 100
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] discriminator remote 101
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] min-tx-interval 100
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] min-rx-interval 100
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] detect-multiplier 3
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] commit
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] quit
```

#### 2. 配置静态路由并关联BFD会话
在H3C设备中，静态路由的配置命令如下，并通过`track`命令关联BFD会话：

```sh
[H3C] ip route-static vpn-instance ChinaMobile_CXINAN 10.88.31.8 255.255.255.248 192.168.31.10 preference 60
[H3C] track 1 bfd session LJDX_CXINAN
[H3C-track-1] quit

[H3C] ip route-static vpn-instance ChinaMobile_CXINAN 10.88.31.8 255.255.255.248 192.168.31.10 preference 60 track 1
```

### 完整的H3C配置
```sh
<H3C> system-view
[H3C] bfd
[H3C-bfd] discriminator local 100
[H3C-bfd] discriminator remote 101
[H3C-bfd] commit
[H3C-bfd] quit

[H3C] bfd session init-mode active
[H3C] bfd session lsp-trigger enable
[H3C] bfd session vrf ChinaMobile_CXINAN
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] peer-ip 192.168.31.10
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] interface GigabitEthernet 3/0/3.2040
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] source-ip 192.168.31.9
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] discriminator local 100
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] discriminator remote 101
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] min-tx-interval 100
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] min-rx-interval 100
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] detect-multiplier 3
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] commit
[H3C-bfd-session-vrf-ChinaMobile_CXINAN] quit

[H3C] ip route-static vpn-instance ChinaMobile_CXINAN 10.88.31.8 255.255.255.248 192.168.31.10 preference 60
[H3C] track 1 bfd session LJDX_CXINAN
[H3C-track-1] quit

[H3C] ip route-static vpn-instance ChinaMobile_CXINAN 10.88.31.8 255.255.255.248 192.168.31.10 preference 60 track 1
```

### 解释
- **BFD配置**：
- `bfd`：进入BFD配置模式。
- `discriminator local 100` 和 `discriminator remote 101`：配置本地和远端的BFD会话标识符。
- `bfd session vrf ChinaMobile_CXINAN`：指定VRF实例。
- `peer-ip 192.168.31.10`：配置对端IP地址。
- `interface GigabitEthernet 3/0/3.2040`：指定接口。
- `source-ip 192.168.31.9`：配置源IP地址。
- `min-tx-interval 100` 和 `min-rx-interval 100`：设置最小发送和接收间隔。
- `detect-multiplier 3`：设置检测倍数。

- **静态路由配置**：
- `ip route-static vpn-instance ChinaMobile_CXINAN 10.88.31.8 255.255.255.248 192.168.31.10 preference 60`：配置静态路由。
- `track 1 bfd session LJDX_CXINAN`：创建一个Track项，关联BFD会话。
- `ip route-static vpn-instance ChinaMobile_CXINAN 10.88.31.8 255.255.255.248 192.168.31.10 preference 60 track 1`：配置静态路由并关联Track项。

通过以上配置，H3C设备可以实现类似于华为设备的BFD会话配置和静态路由关联功能。
