300-410 Practice Question: Consider the following configuration on a router…
Consider the following configuration on a router running BGP and OSPF: ```
router bgp 65000
distance bgp 20 200 200 ``` What is the effect of this command?
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
✓
It sets the administrative distance for eBGP routes to 20, iBGP routes to 200, and local BGP routes to 200.
The `distance bgp` command sets AD for BGP routes: external (eBGP) to 20, internal (iBGP) to 200, and local to 200.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It sets the administrative distance for eBGP routes to 20, iBGP routes to 200, and local BGP routes to 200.
Why this is correct
Syntax: `distance bgp <external> <internal> <local>`.
- ✗
It sets the administrative distance for all BGP routes to 20.
Why it's wrong here
The command has three parameters.
- ✗
It sets the administrative distance for eBGP routes to 200 and iBGP routes to 20.
Why it's wrong here
The order is external, internal, local.
- ✗
It sets the administrative distance for BGP routes to 20 for routes learned from AS 65000.
Why it's wrong here
The command does not reference the local AS.

Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
