Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Weight, then Local Preference, then Locally Originated, then AS_PATH Length, then MED

BGP best path selection follows a specific order: weight, local preference, locally originated, AS_PATH length, MED.

Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.

✓
Weight, then Local Preference, then Locally Originated, then AS_PATH Length, then MED
Why this is correct
This is the correct order because BGP's best path selection algorithm evaluates attributes in this specific sequence: highest weight first, then highest local preference, then prefer locally originated routes, then shortest AS_PATH, then lowest MED.
✗
Local Preference, then Weight, then Locally Originated, then AS_PATH Length, then MED
Why it's wrong here
This is incorrect because weight has higher precedence than local preference. Local preference is considered only if weight is equal or not set.
✗
Weight, then Local Preference, then AS_PATH Length, then MED, then Locally Originated
Why it's wrong here
This is incorrect because locally originated routes are preferred over shorter AS_PATH and MED. The 'locally originated' check occurs before AS_PATH length comparison.
✗
Weight, then AS_PATH Length, then Local Preference, then Locally Originated, then MED
Why it's wrong here
This is incorrect because local preference is evaluated before AS_PATH length. AS_PATH length is only considered after local preference is compared.
