Below are the advantages and disadvantages: Advantages Below are the advantages: Open Short Path First is easily scalable, meaning with a very little amount of hassle, we can scale it to use in a very big network. Open Shortest Path First Protocol has full support for subnets. Use of Hello...
OSPF routers select a DR and a BDR for every Ethernet broadcast segment. For example, if you have twenty VLANs in your switched area, you’ll have twenty DRs and twenty BDRs. An OSPF router talks to a DR using the IP multicast address 224.0.0.6. The DR and the BDR talk to all OSPF...
However, there are a few disadvantages: OSPF is quite CPU and memory intensive due to the SPF algorithm and maintenance of multiple copies of routing information; more complex protocol to implement compared to RIP; RouterOS implements the following standards: ...
maintenance. This paper introduces the basic principle of VPN and several important implementation technologies. This paper analyzes and compares the advantages and disadvantages of SSL VPN and IPSec VPN, and explains how to use SSL VPN technology to build enterprise intranet. This paper summarizes SSL...
Each router interface needs a valid IP address to run. This command matches the given IP address with the IP address of all interfaces. If an interface's IP address matches the given IP address, it enables the OSPF process on that interface and adds that interface to the specified OSPF are...
This paper pre-tends to give a vision to the reader of the potential of GMPLS framework and analyze the advantages and disadvantages to use OSPF-TE instead BGP for autodiscovery purposes in a layer one virtual private network for an specific network scenario....

What are the advantages and disadvantages of OSPF? no limitation on the hop count. intelligent use of Variable Length Subnet Masks (VLSM) is very useful in IP address allocation. IP multicasting to send link-state updates. better convergence than RIP. ...
It should be noted that forwarding IP multicasts as data-link unicasts has some disadvantages when three or more MOSPF routers are attached to the network. First of all, it is more work for a router to send multiple unicasts than a single multicast. Second, the multiple unicasts consume ...
