What Is the Default Administrative Distance for IPv6 Static Routes?
This 300-410 practice question tests your understanding of ipv6 traffic filtering and urpf. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
What is the default administrative distance for IPv6 static routes in Cisco IOS-XE?
Quick Answer
The answer is 1. The default administrative distance for IPv6 static routes in Cisco IOS-XE is 1, identical to the default for IPv4 static routes, because both protocols use the same underlying routing table logic where directly connected routes hold a distance of 0 and static routes are the next most preferred manually configured path. On the Cisco CCNP ENARSI 300-410 exam, this concept tests your understanding that administrative distance is a universal trustworthiness metric, not a protocol-specific value, so you must remember that IPv6 static routes are not assigned a higher default distance like some dynamic protocols. A common trap is assuming IPv6 static routes have a different default, such as 5 or 20, because of the separate address family, but Cisco maintains consistency across both IP versions. For a quick memory tip, think “static is number one” for both IPv4 and IPv6, as the distance of 1 reflects the administrator’s direct control over the route.

Correct answer & explanation
✓
1
The default administrative distance for IPv6 static routes in Cisco IOS-XE is 1. This is because Cisco assigns a default administrative distance of 1 to all static routes, including IPv6 static routes configured with the 'ipv6 route' command. This value ensures that static routes are preferred over most dynamic routing protocols like OSPF (110) or EIGRP (90/170) but are less preferred than directly connected interfaces (0).
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the administrative distance of IPv6 static routes with that of IPv4 static routes (both are 1) or mistakenly think IPv6 static routes have a different default distance due to IPv6-specific routing protocols, leading them to select 20 (eBGP) or 0 (connected) instead.
Detailed technical explanation
How to think about this question
Under the hood, the administrative distance for IPv6 static routes is defined in the Cisco IOS-XE routing table as a 1, identical to IPv4 static routes, and can be overridden using the 'ipv6 route' command with an optional distance parameter (e.g., 'ipv6 route 2001:db8::/32 GigabitEthernet0/0 10' sets distance to 10). A subtle behavior is that if a static route points to an interface without a next-hop IP (e.g., 'ipv6 route 2001:db8::/32 GigabitEthernet0/0'), it is considered a directly attached static route and still has a default distance of 1, but it may be installed only if the interface is up and has an IPv6 address. In real-world scenarios, network engineers use this default distance to ensure static routes override dynamic routes for traffic engineering, such as backup paths or policy-based routing.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.

Quick reference
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.
