300-410 Practice Question: Consider the following partial configuration on…
Consider the following partial configuration on router R6:
router bgp 65001
bgp router-id 6.6.6.6
neighbor 10.0.0.2 remote-as 65002 neighbor 10.0.0.2 route-map SET-MED out
! route-map SET-MED permit 10 set metric 50
What is the effect of this configuration?
⚠ Common exam trap
Test-takers frequently assume a route-map must have a match clause to be valid, but Cisco permits a route-map with only a set clause, which then applies to all routes matched by the permit statement.
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
✓
The route-map will set the MED to 50 for all routes advertised to neighbor 10.0.0.2, and all routes will be advertised.
The route-map SET-MED is applied as an outbound route-map on the BGP neighbor 10.0.0.2. Since the route-map has a permit statement with no match clause, it implicitly matches all routes. The set metric 50 command then sets the MED (Multi-Exit Discriminator) to 50 for all routes advertised to that neighbor. All routes are still advertised because the route-map does not contain any deny statements or match conditions that would filter them.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Only routes that match a specific prefix will have MED set to 50; other routes will not be advertised.
Why it's wrong here
Without a match clause, the route-map permits all routes. All routes will have MED set to 50 and will be advertised.
- ✓
The route-map will set the MED to 50 for all routes advertised to neighbor 10.0.0.2, and all routes will be advertised.
Why this is correct
The route-map has no match, so it matches all routes. The set metric command applies to all matched routes, setting MED to 50.
- ✗
The configuration is invalid because the route-map must have a match clause.
Why it's wrong here
Route-maps can have no match clause; they then match all routes. This is valid.
- ✗
The MED will only be set if the neighbor is also configured with a route-map for inbound updates.
Why it's wrong here
The route-map is applied outbound, so it affects routes sent to the neighbor. No inbound route-map is required.
