when a network contains discontiguous network addresses
R1 is originating the route 172.30.200.32/28. Automatic summarization is disabled. The 172.30.200.16/28 network is one hop away from R1. A classful routing protocol is being used.
There are two types of summarization: Inter-area route summarization External route summarization i) Inter-Area Route Summarization Inter-area route summarization is done on ABRs and it applies to routes from within the AS. It does not apply to external routes injected into OSPF via redistribution. In order to take advantage of summarization, network numbers in areas should be assigned in a contiguous way to be able to lump these addresses into one range. To specify an address range, perform the following task in router configuration mode: area area-id range address mask Where the "area-id" is the area containing networks to be summarized. The "address" and "mask" will specify the range of addresses to be summarized in one range. The following is an example of summarization: External route summarization i) External route summarization is specific to external routes that are injected into OSPF via redistribution. Also, make sure that external ranges that are being summarized are contiguous. Summarization overlapping ranges from two different routers could cause packets to be sent to the wrong destination. Summarization is done via the following router ospf subcommand:
PING command verifies the existence of a node on a network. Ping command is a command of command line interface . It is used to check if the host is alive or not.
Yes, that is the reason network administrators use automatic addressing.
I believe you are talking about the "PING" command. Open a "command" prompt and type ping/? it will give you all the parameters.

To create route summarization, there are some necessary requirements:Routers need to be running a classless routing protocol, as they carry subnet mask information with them in routing updates. (Examples are RIP v2, OSPF, EIGRP, IS-IS, and BGP.)Addresses need to be assigned in a hierarchical fashion for the summarized address to have the same high-order bits. It does us no good if Winnipeg has network 172.16.64.0 and 172.16.67.0 while 172.16.65.0 resides in Calgary and 172.16.66.0 is assigned in Edmonton. No summarization could take place from the edge routers to Vancouver.Tip:Because most networks use NAT and the 10 network internally, it is important when creating your network design that you assign network subnets in a way that they can be easily summarized. A little more planning now can save you a lot of grief later.
VLSM (Variable Length Subnet Mask) Allows more than one subnet mask to exist within a network allows subnetting of an already subnetted network address. More Efficient use of IP addresses- Without the use of VLSM, companies must implement a single subnet mast within an entire Class A, B, or C network number. Greater capability to use route summarization - VLSM allows more hierarchical levels within an addressing plan and thus allows better route summarization within routing tables. Isolation of topology changes from other routers- Another advantage to using VLSM enabled route summarization in a large, complex network is that it can isolate topology changes from other routers.

To configure EIGRP to advertise specific subnets only, use the "wild card mask" option with the network command.
