JNCIP-ENT BGP Advanced Practice Question
An engineer needs to ensure that a Junos router balances BGP traffic across multiple paths with unequal IGP costs. Which feature must be configured to achieve this?
Answer choices
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
✓
BGP multipath with the 'as-path-relax' or equivalent multipath options enabled.
By default, BGP multipath requires equal cost. To allow paths with different costs, 'as-path-multipath' or variance-based multipath configurations are required depending on specific Junos platform support, but generally standard multipath requires equal IGP cost unless specific multipath relaxation options are set.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Setting the MED attribute to zero on all incoming EBGP updates.
Why it's wrong here
MED affects path selection priority, not multi-path load balancing.
- ✓
BGP multipath with the 'as-path-relax' or equivalent multipath options enabled.
Why this is correct
Relaxing strict AS path or IGP cost checks allows multipath load balancing across paths with different metrics.
- ✗
Configuring static routes with identical preferences for every BGP prefix.
Why it's wrong here
Static routes cannot dynamically scale to handle thousands of BGP learned prefixes.
- ✗
Enabling BGP Route Reflection on the local routing engine.
Why it's wrong here
Route reflection is an IBGP scalability feature, not a load-balancing mechanism.
