Final answer:
The default administrative distances for different route types are mentioned along with the explanation of administrative distance and an example.
Step-by-step explanation:
The default administrative distances for different route types are:
- EIGRP internal routes - 90
- EIGRP external routes - 170
- OSPF - 110
- RIP - 120
- Static routes - 1
The administrative distance is a measure of the trustworthiness of a routing protocol. When multiple routing protocols are used, the one with the lowest administrative distance is chosen as the best route.
For example, if there is an EIGRP internal route and an OSPF route to the same destination, the router will choose the EIGRP internal route as it has a lower administrative distance of 90 compared to OSPF's 110.
