Chapter 17 Flashcards
administrative distance
administrative distance
In Cisco routers, a means for one router to choose between multiple routes to reach the same subnet when those routes were learned by different routing protocols. The lower the administrative distance, the better the source of the routing information.
ARP table
ARP table
A list of IP addresses of neighbors on the same VLAN, along with their MAC addresses, as kept in memory by hosts and routers.
connected route
On a router, an IP route added to the routing table when the router interface is both up and has an IP address configured. The route is for the subnet that can be calculated based on the configured IP address and mask.
default route
default route
On a router, the route that is considered to match all packets that are not otherwise matched by some more specific route.
floating static route
A static IP route that uses a higher administrative distance than other routes, typically routes learned by a routing protocol. As a result, the router will not use the static route if the routing protocol route has been learned, but then use the static route if the routing protocol fails to learn the route.
host route
host route
A route with a /32 mask, which by virtue of this mask represents a route to a single host IP address.
network route
A route for a classful network.
next-hop router
next-hop router
In an IP route in a routing table, part of a routing table entry that refers to the next IP router (by IP address) that should receive packets that match the route.
outgoing interface
outgoing interface
In an IP route in a routing table, part of a routing table entry that refers to the local interface out which the local router should forward packets that match the route.
static route
static route
An IP route on a router created by the user configuring the details of the route on the local router.
