## 九、命令语法说明
### 9.1 重要注意事项
1. **LDP命令必须指定instance**:`show mpls ldp neighbor brief instance <id>` ✅
- `show mpls ldp neighbor brief` ❌ Incomplete command
2. **BGP VPNv4路由查询**:`show bgp vpnv4 unicast vrf <vrf-name> route` ✅
- `show bgp vpnv4 unicast rd-by-vrf <vrf-name>` ❌ Incomplete command
- `show bgp ipv4 unicast route` ❌ Ambiguous command
3. **VRF路由查询**:`show ip forwarding route vrf <vrf-name>` ✅
- `show ip route vrf <vrf-name>` ❌ Invalid input
- `show ipv4 route vrf <vrf-name>` ❌ Invalid input
4. **OSPFv3命令特点**:
### 9.2 特殊字符限制
netx平台限制了管道符等特殊字符的使用,建议分步执行命令。
- OSPFv3使用`show ipv6 ospf`前缀,而不是`show ip ospf`
- OSPFv3数据库LSA类型与OSPFv2不同:Type-1/2/3/4/5对应router/network/inter-prefix/inter-router/external
- OSPFv3新增Type-7(Link-LSA)、Type-8(Intra-Prefix-LSA)等IPv6特有LSA
- OSPFv3支持SRv6 Locator LSA(`show ipv6 ospf database srv6-locator`)
- OSPFv3请求列表和重传列表需要指定邻居或接口参数
5. **IS-IS命令特点**:
---
- IS-IS支持多进程:设备上有多个IS-IS进程实例(如进程0、1、5、44、101等)
- Level分离:大多数命令支持`level-1`和`level-2`选项,分别查看L1/L2信息
- IPv4/IPv6分离:路由查询使用`show isis ipv4 route`和`show isis ipv6 route`
- LSP标识符格式:`system-id.xx-xx*`(如MER1.00-00*)
- 灵活算法支持:`flex-algorithm`参数用于查看特定算法的路由
- Segment Routing集成:通过`show isis segment-routing prefix-sid-map`查看SR映射
- 快速重路由:支持LFA、Remote-LFA、TI-LFA三种保护方式
6. **BGP命令特点**:
**文档维护**:
- 最后更新:2026-07-22
- 验证设备:MER1 @ 10.229.234.136
- 关联文档:`命令探索方法论.md`、`BGP跨域排障命令速查.md`
- BGP支持多种地址族:IPv4/IPv6单播、VPNv4/VPNv6、EVPN、Link-State等
- BGP IPv4/IPv6命令结构相似,都支持summary、neighbor、detail、community等子命令
- BGP VPNv4/VPNv6需要通过`vrf <vrf-name>`或`rd <rd-value>`来指定VRF
- EVPN支持多种NLRI类型:ethernet-ad、mac、ip-prefix、inclusive-multicast等
- Link-State按protocol和type分类,可以查看ISIS/OSPF/BGP等协议的链路状态信息
- BMP用于监控BGP会话和路由,支持monitor-peer和monitor-route
- SR-EPE和SRv6-EPE用于出向peer工程,支持按AS查询
- RPKI-RTR提供路由源验证功能,支持valid/invalid/not-found状态查询
### 8.2 参数占位符说明
文档中使用以下占位符表示需要替换的参数:
- `<ipv4-address>` - IPv4地址,如`192.168.1.1`
- `<ipv6-address>` - IPv6地址,如`2001:db8::1`
- `<as-number>` - AS号码,如`65001`
- `<vrf-name>` - VRF名称,如`vpn1`
- `<rd-value>` - RD值,如`65001:100`
- `<interface>` - 接口名称,如`gei_1/1`或`loopback1`
- `<process-id>` - 进程ID,如`isis 100`中的`100`
- `<lsp-id>` - LSP标识符,如`MER1.00-00*`
- `<system-id>` - IS-IS系统ID,如`1`
- `<regex>` - 正则表达式,用于匹配AS路径
- `<community>` - BGP团体号,如`65001:100`
- `<route-map>` - 路由图名称
- `<ug-index>` - 更新组索引号
- `<name>` - 名称标识符
- `<prefix>` - 网络前缀
- `<mac-address>` - MAC地址,如`00:11:22:33:44:55`
- `<index-value>` - 索引值
- `<neighbor>` - 邻居IP地址
- `<algo-id>` - 灵活算法ID
### 8.3 特殊限制
netx平台对命令数量有限制,可以多次采集
