EIGRP SUMMARY ROUTE CALCULATOR MANUAL

Manual summarization is configured on a per-interface basis. If a packet matches one of the child routes, it forwards out the. The Null0 interface indicates that this is not an actual path, but a summary for advertising purposes. EIGRP installs a Null0 summary route in the routing table for each parent route. This procedure reduces the size of the routing table by aggregating a group of routes into a single route that is advertised to the other routers. The summary route is called the parent route and the subnet routes are called the child routes. As a summary, Administrative Distance allows us to select the route between different routing protocol route alternatives toward the same destination. Because the preference value of static route is lower than OSPF. Therefore the summary route is: 10.3.4.0/22 or subnet mask 255.255.252.0. So, if we have two routes to the same destination in the routing table, static route will be selected as best route. A single route can be used to represent multiple routes, which reduces the size of routing tables in a network. To calculate the mask, count all the bits in red. Aside from the fact that IPv6 addresses are 128 bits long and written in hexadecimal, summarizing IPv6 addresses is actually similar to the summarization of IPv4 addresses. One of the advantages of EIGRP over some other routing protocols (like OSPF) is that manual summarization can be done on any router within a network. What is the difference between IPv4 and IPv6 summary routes? The calculation and configuration of an IPv6 summary static route is similar to the configuration of an IPv4 static summary route. What is IP address/route summary? What is IP Address/Route Summary ? Example with Explanation What is IP Address Route Summary? IP Address route summation which is also known as route aggregation, is the process routers use in advertising volume or set of IP addresses as a single address with shorter subnet mask (CIDR). There comes a time when a network becomes too large to manage and performance numbers hit the low as a result of too much traffic. What is the IPv6 subnet calculator? IPv6 Subnet Calculator The IPv6 Subnet Calculator performs network calculations on the given network address block, routing prefix and determines subnet address, host range and notation for the subnet.

Count the number of far left matching bits to determine the prefix length for the summary route. The result supernet of these networks is 192.168.0.0/21.

Convert result back to dotted-decimal format and add routing prefix. End the same bit string with zeroes, so that there are 32 bits. Convert the differing section from hex to binary. Count how many bits does the common pattern have - it will be used as network prefix.

List the network addresses (prefixes) and identify the part where the addresses differ.
