The significance of route summarization is that the number of routes in the routing tables are reduced. This reduces the bandwidth used to update those routes from one router to another. It also reduces the memory requirements and CPU load of the router. This is relevant both within an organization, and worldwide.One interesting details is that the worldwide routing BGP routing tables currently (as of 2017) contain over half a million routes. This is already getting to be too much for some older routers. Once IPv6 gets used on a larger scale, that problem should be mitigated, since in IPv6, addresses are set up in a more hierarchical way, making it easier to summarize routes.

What is the different type of route summarization available in OSPF?
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:

Explain the benefits gained by network designers through the use of VLSM?
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.
What two pieces of information can be detemined from output?
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.
