Floating static routes are static routes that have an administrative distance greater than the administrative distance of another static route or dynamic routes. They are very useful when providing a backup to a primary link, as shown in Figure 2-66.
Why would a floating static route be configured?
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.
How do you summarize a static route?
Summary Static Route Calculation
Write out the network addresses to be summarized in binary.Next, let’s find the subnet mask for summarization. Count the number of far-left matching bits. To find the network address for summarization, copy the matching 22 bits and add all 0 bits to the end to make 32 bits.
How do I create a static IPv6 address?
The information needed for configuring a static IP address can be obtained from your ISP.
Choose IPv6 > IPv6 WAN (Internet).In the WAN (Internet) Address (IPv6) field, choose Static IPv6.Enter the IPv6 IP address assigned to your router.Enter the IPv6 prefix length defined by the ISP.
Which of the following is characteristics of a static route?
Static routes are not advertised over the network, resulting in better security. Static routes use less bandwidth than dynamic routing protocols, as routers do not exchange routes. No CPU cycles are used to calculate and communicate routes. The path a static route uses to send data is known.
How do I set a static IPv6 route in Linux?
7.4. Add an IPv6 route through an interface
7.4. Using “ip” Usage: # /sbin/ip -6 route add
How do I set administrative distance for a static route?
To set an administrative distance:
For RIP and OSPF, issue the distance command in Router Configuration mode. host1(config-router)#distance 100. The range for administrative distance is 0–255. For IS-IS, issue the distance ip command in Router Configuration mode. host1(config-router)#distance 80 ip.
What should be altered to enable static route to become a floating static route?
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. R1 can use R2 or R3 to get to the 192.168. 23.0/24 network.
Is there DHCP for IPv6?
The Dynamic Host Configuration Protocol for IPv6 (DHCP) enables DHCP servers to pass configuration parameters such as IPv6 network addresses to IPv6 nodes. It offers the capability of automatic allocation of reusable network addresses and additional configuration flexibility.
What is DHCP IPv6?
DHCPv6 is a method to assign IPv6 addresses automatically to network clients. When you enable IPv6 for a trusted or optional interface, you can enable the DHCPv6 server on the interface, to assign IPv6 addresses to clients that connect.
What’s a static IP address?
Static IP addresses
If your computer is hosting a web server, its IP address is what identifies it to the rest of the Internet. A computer on the Internet can have a static IP address, which means it stays the same over time, or a dynamic IP address, which means the address can change over time.
