Day 15 - Static and Default Route Configuration Flashcards
What are some the reasons you would use a static route?
In a small network that only requires simple routing
In a hub and spoke network topology
When you want to create a quick ad hoc route
As a backup route when the primary route fails
Static routes are commonly used when you are routing from a larger network to a __________ network (a network accessed by a single link)
Stub
What is the basic first part of the command for a static route?
ip route
Define each of these subsets of a static ip route
1 2 3 ip route 192.168.1.0 255.255.255.0 192.168.2.1
- Destination network address
- Subnet mask of the remote network to be added to the routing table
- Next hop router’s IP address
In lieu of a next hop IP address, what could you could use to tell the router where to forward the packet?
exit interface
Based on the topology, create static routes for all networks that R1 isn’t directly connected to
ip route 172.16.1.0 255.255.255.0 172.16.2.1
ip route 192.168.0.0 255.255.255.0 172.16.2.1
ip route 192.168.1.0 255.255.255.0 172.16.2.1
ip route 10.10.10.0 255.255.255.0 172.16.2.1
Configuring a next hop address requires the router to perform a what?
A recursive lookup to find the exit interface
To avoid a recursive lookup in a ip route, what could you use instead?
Use the exit interface instead of the next hop IP address
What would an exit interface being included in an ip route command look like? For example: Gi1/0/1
ip route 172.16.0.0 255.255.255.0 gi1/0/1
What letter represents a static route in the routing table?
S
When you use the exit interface command instead of the next hop address in a static ip route, what is different in the routing table?
It will show the route as directly connected instead of showing “via {next-hop-address}
A default route is a route that matches what?
All packets
What is another name for a default route?
Quad zero route
Give R2 a default route with it’s exit interface pointing towards HQ
ip route 0.0.0.0 0.0.0.0 serial 0/1/0
What does S* stand for in the routing table?
A static route that is a candidate for a default route
