What is a floating static route?
ip route 209.165.200.228 255.255.255.248 serial 0/0/0 ip route 172.16.0.0 255.248.0.0 10.0.0.1 Explanation: Floating static routes are used as backup routes, often to routes learned from dynamic routing protocols. To be a floating static route, the configured route must have a higher administrative distance than the primary route.
What is the administrative distance of a Static Static route?
For example, if the primary route is learned through OSPF, then a floating static route that serves as a backup to the OSPF route must have an administrative distance greater than 110. The administrative distance on a floating static route is put at the end of the static route: ip route 209.165.200.228 255.255.255.248 10.0.0.1 120.
What is the difference between static and dynamic routing in R1?
R1 can use R2 or R3 to get to the 192.168.23.0/24 network. Static routes have a very low administrative distance of 1, this means that your router will prefer a static route over any routes that were learned through a dynamic routing protocol.
What is the difference between static and dynamic routing protocols?
By default, dynamic routing protocols have a higher administrative distance than static routes. Configuring a static route with a higher administrative distance than that of the dynamic routing protocol will result in the dynamic route being used instead of the static route.
Which of the following is the correct syntax of a floating static route?
Explanation: Floating static routes are used as backup routes, often to routes learned from dynamic routing protocols. To be a floating static route, the configured route must have a higher administrative distance than the primary route.
What is the syntax for static route?
To configure a static route, the command could be: Router(config)#ip route 10.2. 3.0 255.255. 255.0 192.168.
What is a floating static route?
A floating static route is used as a backup route. It has a manually configured administrative distance greater than that of the primary route and therefore would not be in the routing table until the primary route fails. You will test failover to the backup route, and then restore connectivity to the primary route.
How do you make a floating static route?
To create floating static route(s) you will create identical routes that already exist which go to R2 through the main frame-relay link to traverse the point to point link which have a higher administrative distance so as long as Serial0/0 is up traffic will take that path but if Serial0/0 fails the router will re- ...
What does IP route 0.0 0.0 0.0 0.0 mean?
In IPv4-based routing, 0.0. 0.0 serves as a default route. This means no particular address has been designated in the routing table as the next hop in the packet's path to its final destination. When the default route is used with a subnet mask of 0.0.
What are 4 types of static routes?
There are four types of a static route. These types are the static network route, static host route, fix static route, and the floating static route. Each type uses the above information in a different way. Let's discuss the above information and how each type uses the above information.
What is the correct syntax for an IPv6 static route?
IPv6 also has a default static route similar to the IPv4 quad zero (0.0. 0.0) static default route. Instead, the IPv6 command uses the ::/0 notation to specify all networks. For example, a default static route as specified by the “::/0” entry is configured on router R2 to reach all other networks connected to R1.
What is the command for static route in Cisco router?
In order to configure static routing in Cisco IOS routers, this is the command to use. The IP route command includes the destination network followed by a mask and so you can insert CIDRE or Classless Inter-Domain Routing Entries pointing to subnets with multiple mask sizes.
Which setting must be modified when configuring a static route as an EIGRP floating route?
The floating static route must be configured with a higher administrative distance than EIGRP. EIGRP has an administrative distance of 90. If the floating static route is configured with an administrative distance of 95, the dynamic route learned through EIGRP is preferred to the floating static route.
How do I add a static route?
How to Add a Static Route to the Routing TableView the current state of the routing table. ... Assume the Primary Administrator role or become superuser. ... (Optional) Flush the existing entries in the routing table. ... Add a route that persists across system reboots.
What is the command for static route in Cisco router?
In order to configure static routing in Cisco IOS routers, this is the command to use. The IP route command includes the destination network followed by a mask and so you can insert CIDRE or Classless Inter-Domain Routing Entries pointing to subnets with multiple mask sizes.
What is static route What is the syntax for static route What is the main advantage of static routing over dynamic routing?
Static routing uses small routing tables with only one entry for each destination. It also requires less computation time than dynamic routing because each route is preconfigured. Because static routes are preconfigured, administrators must manually reconfigure routes to adapt to changes in the network when they occur.
How do I create a static route in Cisco?
Perform these steps to configure a default route.Enter global configuration mode. device# configure terminal.Enter 0.0. 0.0 0.0. ... (Optional) Enable the default network route for static route next-hop resolution. ... (Optional) Configure next-hop recursive lookup to resolve the next-hop gateway.
What is static routing?
Static routes have a very low administrative distance of 1, this means that your router will prefer a static route over any routes that were learned through a dynamic routing protocol. If we want to use a static route as a backup route, we’ll have to change its administrative distance. This is called a floating static route.
What is the administrative distance of RIP?
The administrative distance of RIP is 120 so if we pick a higher number, our static route will be used as a backup. Let’s try 121:
What network can R1 use?
R1 can use R2 or R3 to get to the 192.168.23.0/24 network.
Can you use static routes with a higher administrative distance?
You have now learned how you can configure static routes with a higher administrative distance, turning them into floating static routes. You can use these as a backup for routes that were learned through dynamic routing protocols (or other static routes with a lower administrative distance).
Do you need to configure AD when you configure your static route?
The trick is that you need to configure an AD when you configure your static route. Here’s how:
Does R3 have a route?
There we go, R1 has a route. What if we want to use R3 as a backup? R3 is not running any routing protocols, so we have to use a static route. This is a possibility when the router is outside of your control.
Is RIP slow?
RIP is a pretty slow routing protocol, so you have to wait awhile for the route to disappear. After awhile, you will see the changes in the routing table of R1:
Why is static routing more secure?
Static routing is more secure because it does not advertise over the network.
What are the advantages of static routing over dynamic routing?
What are two advantages of static routing over dynamic routing? (Choose two.)#N#Static routing is more secure because it does not advertise over the network.#N#Static routing scales well with expanding networks.# N#Static routing requires very little knowledge of the network for correct implementation.#N #Static routing uses fewer router resources than dynamic routing.#N#Static routing is relatively easy to configure for large networks.
Is static route removed from routing table?

What is floating static route?
Floating static routes are used as backup routes, often to routes learned from dynamic routing protocols. To be a floating static route, the configured route must have a higher administrative distance than the primary route.
Is static routing easy to configure?
Static routing uses fewer router resources than dynamic routing.*. Static routing is relatively easy to configure for large networks. Static routing requires a thorough understanding of the entire network for proper implementation.
