Which of the following is the MED attribute value in BGP of Huawei equipment?

Question

Options

• A180
• B0
• C100
• D10

• A
  5% (2)
• B
  77% (30)
• C
  13% (5)
• D
  5% (2)

Explanation

In BGP, the MED (Multi-Exit Discriminator) attribute defaults to 0 on Huawei equipment when a route is originated locally and no MED value has been explicitly configured. A value of 0 is the lowest possible MED, and since BGP prefers the lowest MED when comparing paths from the same neighboring AS, this default makes locally originated routes competitive without manual tuning.

Option A (180) and Option D (10) are arbitrary numbers with no basis in BGP standards or Huawei defaults. Option C (100) is the classic distractor here because 100 is the default value of the LOCAL_PREF attribute, not MED - confusing these two is a very common mistake.

Memory tip: Keep MED and LOCAL_PREF straight by pairing their defaults with their scope. MED is shared outward to neighbors and starts at zero; LOCAL_PREF stays internal to your AS and defaults to 100. Zero for the one that leaves, one hundred for the one that stays.
