About this chapter

What this chapter covers

Firewall Hot Standby Technologies is 10% of the Huawei HCIA-Security H12-711 exam. It covers why two firewalls are paired, how VRRP, VGMP and HRP work together, the active/standby and load sharing modes, and the basic networking and configuration of a hot standby pair.

Questions are single-answer, multiple-answer without a stated count, true/false, drag and drop and typed fill-in-the-blank, often "Which of the following statements is true?". Many show two firewalls with a heartbeat link between them, a VRRP or HRP configuration, or display hrp state and display vrrp brief output, and ask which firewall forwards traffic.

It has 2 outline topics, and two pages cover them.

How the topics fit together

The fundamentals explain why stateful firewalls cannot rely on VRRP alone and how VGMP and HRP fix that. The networking page then applies those ideas to real topologies and configuration.

A router pair can switch over with VRRP alone, but a firewall pair must also carry its session table across, or every existing connection breaks.

Exam tip

Keep the three protocols apart. VRRP gives the virtual gateway address, VGMP decides which firewall is active, and HRP copies configuration and sessions from the active to the standby.

How to use these pages

Each topic page has the same shape, so you can skim for what you need.

  • What it is: the idea in plain words.
  • How it works: the mechanism, with tables and examples.
  • What to remember for the exam: the facts to memorize.
  • Common mistakes: the classic traps.
  • Check yourself: three questions to test your understanding.

Read each configuration snippet and say what it does before reading the explanation. The exam often shows a short configuration and asks which traffic is permitted, translated or allowed to log in.
