IGRP is a distance-vector routing protocol developed by Cisco. The default hop count in IGRP is 100, and the maximum hop count is 255. IGRP's default metrics are bandwidth and line latency, but it can optionally use reliability, load, and MTU.

STP is used to prevent switching loops in switching networks, whereas RSTP is nearly identical to STP with the exception that port forwarding timing has been reduced to zero.

The types of routes allowed in stub area are:

The external routes are not advertised in this area.

Street number and name are the components of the access layer.

The city name is the component of the distribution layer.

The state name is the component of the core layer.

Postal address: It has three components called state, city, and street that are used to deliver mail. A mail can be delivered to the next post office based on only the City, state, and street information.

Telephone number: It has an area code and exchange. It is delivered at the core layer based on the area code.

The six different types of OSPF routes are:

The three classes of routing protocols are:

The interface metric in a narrow metric is 6 bits long, and the path metric is 10 bits long. The interface metric of a wide metric is 24 bits long, while the path metric is 32 bits long.

Type-1 LSAs are router LSAs that each router generates for the area to which it belongs.

Type-2 LSAs, often known as network LSAs, are generated by the DR and BDR.

Redistribution of Level 2 routes into an area as Level l routes.

To connect a nonzero area to the backbone if the nonzero area becomes disconnected from the backbone. A virtual link can also be used if the backbone, or area 0, becomes discontiguous.

OSPF databases on routers in the same area must be identical. If route summarization was allowed within an area, some routers would have specific routes and some routers would have summary routes for routers in the area. If this were allowed, the databases for the area would never agree.

Hold-down timers prevent regular update messages from reinstating a route that might have gone bad. Hold-down timers also tell routers to hold for a period of time any changes that might affect routes.

Routing moves a letter or telephone call to the access layer.

Switching makes the final delivery. A switching decision is made on the part of the address that is not used in routing.

Intra-area, inter area, El, E2, Nl, and N2.

A default route is used if there is not a specific entry in the routing table for the destination.

A postal address has three components that can be used to deliver mail: state, city, and street. A phone number has an area code and exchange. At the core layer, mail can be delivered to the next post office based on only the state or city and state information. A phone number is delivered at the core layer based on the area code.

I have one table (seeker into) that like :

--------------------------------------------------

SeekerID -  SeekerName - SeekerSex - SeekerMobile

12121    -  mmmm       - Male      - 067676767

13223    -  ssss       - Female    - 078876767

And another desk (SeekerCources) that like (every seeker most have three courses):

I want to make a pick out assertion that preview information from two tables seems like this:

SeekerID -  SeekerName - SeekerSex - SeekerMobile - Cource1 - Cource2 - Cource3

12121    -  mmmm       - Male      - 067676767    - MCSA    - MCPD    - *NULL*

13223    -  ssss       - Female    - 078876767    - CCNA    - CCNP    - MCTS

A character which is not an alphabet or numeric character is called a special character. We should remove all the special characters from the string so that we can read the string clearly and fluently. Special characters are not readable, so it would be good to remove them before reading.

Java replaceAll() method of String class replaces each substring of this string that matches the given regular expression with the replacement.

public String replaceAll(String regex, String replacement)

regex: It is the regular expression to which string is to be matched. It may be of different types.

replacement: The string to be substituted for the match.

It returns the resultant String. It throws PatternSyntaxException if the regular expression syntax is invalid. The above method yields the same result as the expression:

Pattern.compile(regex).matcher(str).replaceAll(repl)

how to remove special characters from string in a file using java

Thru my research on CCNP course, while sniffing EIgrp packets, I noticed that packets have IP TTL of two. I additionally validated this for rip. OSPF doesn't have this assets when you consider that it's link state.

Why does the EIGRP and rip have IP TTL of 2?

I already asked one CCIE man or woman, however he did not know.

I came to trust that this could have something to do with frame relay hub&spoke topologies. For example hub routing EIGRP multicasts from one spoke to every other (assuming subinterfaces)?

Why is EIGRP and RIP uses IP TTL of 2 (CISCO)?

I just finished a phone interview. The interviewer asked me a question:

Tell me about what happen about IP packet go through router.

It's been long time since I study networking. And I just say something about router transmission list and there are several router protocols such as OSPF etc. . that's it. Could anybody give a good answer to this? or lead me check some resources?

about IP packet through router

I have string from which I am getting data in array but I am not getting way to get so that I get related data in array like my string is,

[{"Class Room": ["Windows",  "Windows1"],  "Staffroom": ["Windows",  "Windows1"]}],  "


"Class Room" having two values in dropdown Windows and Windows1

"Staffroom" having two values in dropdown Windows and Windows1

How would i get dropdown related value in array i can use split operation but cant getting logic

Above given string is in list, my code is ,

String[] data = list.toString().split(",");


But it split in array then I would not have related data

I want it to split in way so that I would get relative dropdown data in array,

 "Class Room": ["Windows",  "Windows1"], value in aray index 0
   "Staffroom": ["Windows",  "Windows1"]}] value in array index 1

How to split a string to get related data JAVA

I have text file it contains following information.My task is to remove special symbols from that text file.My input file conatins

This is sample CCNA program. it contains CCNP™.
