How do you calculate route summarization?
To calculate the summary route, follow these steps:
- Convert the addresses to binary format and align them in a list.
- Locate the bit where the common pattern of digits ends. (It might be helpful to draw a vertical line marking the last matching bit in the common pattern.)
- Count the number of common bits.
What is the subnet mask 10.0 0.0 8?

| Subnet address | Netmask | Range of addresses |
|---|---|---|
| 10.0.0.0/8 | 255.0.0.0 | 10.0.0.0 – 10.255.255.255 |
| 11.0.0.0/8 | 255.0.0.0 | 11.0.0.0 – 11.255.255.255 |
| 12.0.0.0/6 | 252.0.0.0 | 12.0.0.0 – 15.255.255.255 |
| 16.0.0.0/4 | 240.0.0.0 | 16.0.0.0 – 31.255.255.255 |
How do I summarize a route in OSPF?
To consolidate and summarize routes at an area boundary, use the area range command in the router configuration mode. The ABR will summarize routes for a specific area before injecting them into a different area via the backbone as type 3 summary LSAs.
How do you summarize a route in BGP?
The two techniques for BGP summarization are the following: Static: Create a static route to Null 0 for the prefix, and then advertise the network via a network statement. The downfall to this technique is that the summary route will always be advertised even if the networks are not available.
What is network summarization?
Route summarization is a method where we create one summary route that represent multiple networks/subnets. It’s also called route aggregation or supernetting. Summarization has a number of advantages: Saves memory: routing tables will be smaller which reduces memory requirements.
What is a variable length subnet mask Vlsm and how is it created?
VLSM is a subnet design strategy that allows all subnet masks to have variable sizes. In VLSM subnetting, network administrators can divide an IP address space into subnets of different sizes, and allocate it according to the individual need on a network.
What is a 10.0 0.0 IP address?
IP Address (10.0. 0.0) – It is the global addressing scheme used under Internet Protocol. The IP addresses are allocated to each device and are unique. IP addresses are 32-bit numbers with every 8 bits separated by a decimal.
What is the subnet mask for 10.0 0.0 24?
255.255.255.0

| Subnet address | Netmask | Range of addresses |
|---|---|---|
| 10.0.0.0/24 | 255.255.255.0 | 10.0.0.0 – 10.0.0.255 |
| 10.0.1.0/24 | 255.255.255.0 | 10.0.1.0 – 10.0.1.255 |
| 10.0.2.0/24 | 255.255.255.0 | 10.0.2.0 – 10.0.2.255 |
| 10.0.3.0/24 | 255.255.255.0 | 10.0.3.0 – 10.0.3.255 |
What is summarization in networking?
Route summarization — also known as route aggregation — is a method to minimize the number of routing tables in an IP network. It consolidates selected multiple routes into a single route advertisement. This differentiates it from flat routing, in which every routing table carries a unique entry for each route.
What is BGP summary?
Route Aggregation (RA) also known as BGP Route Summarization is a method to minimize the size of the routing table, announcing the whole address block received from the Regional Internet Registry (RIR) to other ASes.
How do you summarize a network?
How does a subnet mask tell host address bits?
A subnet mask tells hosts on a network whichbits in an address are network address bitsand which bits are host address bits. It does it by the use of 1s and 0s. Consider the table below:
How to calculate the number of networks in a block?
As you can see we have 4 networks, or when we speak in ‘blocks’ it’s a block of 4. Here’s a formula you can use: 256 – number of networks = subnet mask for summary address. The subnet mask will be 255.255.252.0 Another way to look at it is by using the CIDR notation. You know a /24 is a block of 256 addresses.
What kind of IP address does a routing protocol need?
Routing protocols must base their routing decisions on a 32-bit IP address and a prefix length that can be up to 32 bits. Routing updates must carry the prefix length (the subnet mask) along with the 32-bit IP address.
What makes up the rest of an IP address?
An IP address is comprised of a network number (routing prefix) and a rest field (host identifier). A rest field is an identifier that is specific to a given host or network interface. A routing prefix is often expressed using Classless Inter-Domain Routing (CIDR) notation for both IPv4 and IPV6.
