However, if there were other subnets of 172.16.0.0 elsewhere in the network (for example, if 172.16.0.0 were discontiguous), summarizing in this way might not be valid. Cisco routers manage route summarization in two ways: Sending route summaries: Routing protocols, such as RIP and EIGRP, perform automatic route summarization across network boundaries. The other way of affecting the cost of an interface is through the "ip ospf cost" command on the interface itself, this will override the calculated cost. WebRoute summarization simplifies route tables by replacing more-specific addresses with an address that represents all the specific addresses. Because the resulting prefix is bigger than the class C default, from which our network is part of, this process is called supernetting. OSPF uses this graph to run SPF and calculate an SPT for each router in the topology. I see that i'm using 2 subnets -> it's 1 bit -> I subtract 1 bit from the /23 = /22 In Binary format: 172.16.64.0 - - -> Route summarization is a technique that reduces the number of routing entries in a network by grouping them into a single prefix.
