A network engineer runs the following command to troubleshoot an IPsec Site-to-Site VPN issue:
R1# show ip route 192.168.2.0
Routing entry for 192.168.2.0/24 Known via "eigrp 100", distance 90, metric 2684416, type internal Redistributing via eigrp 100 Last update from 10.0.0.2 on Tunnel0, 00:00:23 ago Routing Descriptor Blocks:
* 10.0.0.2, from 10.0.0.2, via Tunnel0
Route metric is 2684416, traffic share count is 1 Total delay is 20000 microseconds, minimum bandwidth is 100000 Kbit Reliability 255/255, minimum MTU 1500 bytes Loading 1/255, Hops 1
What does this output indicate?
⚠ Common exam trap
Cisco often tests the misconception that a route learned via a tunnel interface implies the tunnel is down or that dynamic routing is not functioning, but the presence of a recent update and valid next hop confirms the tunnel is operational.
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 IPsec tunnel is up and EIGRP is exchanging routes over the tunnel.
The output shows a route to 192.168.2.0/24 learned via EIGRP (distance 90) with the next hop 10.0.0.2 reachable through Tunnel0. The last update was 23 seconds ago, confirming the tunnel is up and EIGRP is actively exchanging routing information over the IPsec tunnel. This indicates the IPsec Site-to-Site VPN is functioning and dynamic routing is working correctly.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The route to the remote LAN is not present, indicating a routing issue.
Why it's wrong here
The route is present and learned via EIGRP over Tunnel0.
- ✓
The IPsec tunnel is up and EIGRP is exchanging routes over the tunnel.
Why this is correct
The route is learned via EIGRP on Tunnel0, meaning the tunnel is operational and routing is working.
- ✗
The route is using a static route, not a dynamic routing protocol.
Why it's wrong here
The route is learned via EIGRP, not static.
- ✗
The tunnel interface is down, causing the route to be unreachable.
Why it's wrong here
The route has a last update 23 seconds ago, indicating the tunnel is up.
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.
