Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00133 | $0.03072 |
| Opus 5.5 | $0.00053 | $0.01229 |
| Sonnet 5.5 | $0.00027 | $0.00614 |
| Haiku 4.5 | $0.00013 | $0.00307 |
Grade A, and why
vrrp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

华为交换机 VRRP 配置技能 (vrrp)
适用平台 S 系列 V200R011C10+ ｜ CE 系列 V200R022C00+ 文档来源 华为产品文档 dc_cfg_vrrp_*
VRRP 给终端提供虚拟网关 主备路由器对外表现为一台 终端无感知切换 是局域网三层高可用基础
触发场景
- 配置主备网关 高可用
- 终端网关切换不丝滑 丢包多
- VRRP 优先级 / 抢占调整
- VRRP 主备频繁切换
- VRRP + BFD 实现毫秒级切换
- VRRP + NQA 联动上联探测
- 负载分担（两组互为主备）
- 配置管理 VRRP（堆叠/集群管理用）
VRRP 版本对比
| 版本 | RFC | 支持协议 | 备注 |
|---|---|---|---|
| VRRPv2 | RFC 3768 | 仅 IPv4 | 默认 应用最广 |
| VRRPv3 | RFC 5798 | IPv4 + IPv6 | 双栈支持 改进了认证 |
如混合环境 推荐用 VRRPv3
基本概念
| 术语 | 解释 |
|---|---|
| VRID | 备份组号 1-255 同一备份组成员 VRID 一致 |
| 虚拟 IP | 虚 IP 终端网关 |
| 虚拟 MAC | 自动生成 0000-5e00-01XX（XX=VRID） |
| Master | 主 转发流量 |
| Backup | 备 监听 Master 心跳 |
| 优先级 | 0-255 默认 100 大优 0 表示放弃 |
| 抢占 | 高优先级设备恢复时自动接管 |
配置三步走
1 基础 VRRP（主路由器）
system-view
interface Vlanif 10
ip address 192.168.10.2 24
vrrp vrid 1 virtual-ip 192.168.10.1 # 虚 IP
vrrp vrid 1 priority 120 # 优先级 高
vrrp vrid 1 preempt-mode timer delay 30 # 抢占延时
quit
2 配置备份路由器
system-view
interface Vlanif 10
ip address 192.168.10.3 24
vrrp vrid 1 virtual-ip 192.168.10.1 # 同一虚 IP
vrrp vrid 1 priority 100 # 优先级 低
quit
终端 PC 网关：192.168.10.1（虚 IP）
3 验证
display vrrp
display vrrp brief
display vrrp interface Vlanif 10
正常：主 State=Master 备 State=Backup
高级 联动 BFD（毫秒级切换）
# 1 配 BFD 会话
bfd
quit
bfd to_peer bind peer-ip 192.168.10.3 source-ip 192.168.10.2
discriminator local 1
discriminator remote 2
commit
quit
# 2 VRRP 跟踪 BFD
interface Vlanif 10
vrrp vrid 1 track bfd-session 1 reduced 30
BFD down → 优先级减 30 → 主备切换（毫秒级）
联动 NQA（上联探测）
# 1 NQA 探测上联路由器
nqa test-instance admin to_uplink
test-type icmp
destination-address ipv4 10.1.1.1
frequency 5
start now
quit
# 2 VRRP 跟踪 NQA
interface Vlanif 10
vrrp vrid 1 track nqa admin to_uplink reduced 40
上联失败 → 优先级减 40 → 让出主权
联动接口（跟踪上联接口）
interface Vlanif 10
vrrp vrid 1 track interface GigabitEthernet 0/0/24 reduced 30
上联接口 down → 优先级减 30 → 切换
负载分担（两组互为主备）
让两台路由器都干活 提升资源利用
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

vrrp is a skill published in the GitHub repository nanxiaoyao/network-huawei-skills (2 stars, last pushed 3mo ago), licensed MIT. It adds 133 tokens to every session and 3,072 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
