IPV6 & ACLs

Create an IPv6 design for these requirements: There must be at least 300 networks and no more than 65,000 networks What is the most appropriate prefix? _____________ What is the network address, Prefix, gateway and first host address for the first 5 networks? Network 1….. Design the ACLS for this Scenario   Write the ACL for the following requirements and the statement to apply the ACL to the interface. Show which router and which interface will have the ACL. 1. Users connecting from the internet should be able to access the Web Server using the browser but should not be able to access any other node or network using any other protocol. Replies to requests from company users should be permitted. No other connections should be permitted. 2. Users on Bob's network should be able to browse the internet using http and ftp and access any server except the SQL server on Router C LAN. 3. Amy only should be able to Telnet to any node on the Server Network excluding the SQL server, however no other user from any network should be able to telnet to the Server Network. Users on Amy's network can access Bob's LAN and ping the servers in the Router C LAN including the SQL Server. No other protocols can be used to forward to the SQL server. 4.

They are financial instru- ments whose value depends upon the value of more basic underlying stocks or assets. We will meet a few types of derivative in this course, but among the most prominent will be options . An option is a contract that gives the option holder the right to buy or sell a particular asset either up to or on a specified date in the future, for a price that is agreed upon now. Some terminology and symbols: Call Option . A call option gives the holder the right to buy the underlying asset for a specified price known as the exercise or strike price. Put Option . A put option gives the holder the right to sell the underlying asset during a certain time window for a specified price known as the exercise or strike price. Exercising an option . If an option holder executes their right to buy or sell the underlying asset then they are said to exercise the option. Note that an option holder is not forced to exercise their right to buy/ sell the asset . European Option . In European options the option holder is only allowed to exercise the option at one specified time, known as the expiration date . American Option . In American options the option holder can exercise the right to buy/sell at any time until expiration date . Maturity , Expiration date , Exercise date . These all mean the same thing - the date in the future on which (European), or by which (American), the option to buy/sell the asset must be exercised. Some symbols: T := the expiration date. S t := the price of the asset at time t , so in particular S T := the asset price ( not the option price!!) at expiration date T . K := the exercise price. 2 Option price . The buyer of the option gains protection against risk, whereas the seller is exposing themselves to it. The buyer of the option gains protection against unfavourable movements in the underlying asset price: the holder of a put option knows that they can always get at least K for it whatever happens to the price of the asset in the market, whereas the holder of a call option knows that they will have to spend at most K to buy the asset at time T , however high the price of the asset may be in the market at time T . In order to gain this protection against risk the holder of the option has to pay the seller of the option a fee - the option price . More symbols: in this document we will use: P t ( T; K ) := the price at time t of a European put option with expiration date T and strike price K . We will also use: C t ( T; K ) := the price at time t of a European call option with expiration date T and strike price K . Payoff . Suppose that you are the holder of a European call option to buy a stock for strike price K at time T . Then you would only bother to exercise the option if it the market price of the stock at time T turned out to be more than K , in which case the option would give you a payoff of S T
