CIsco CCNP BSCI Exam Tutorial Introduction To Policy Routing

May 30th, 2008

Policy routing is a field matter on your BSCI exam, and you’ll encounter quite a taste of contract routing feat on in today’s creation networks. But what meet is contract routing?

Policy-based routing, mostly referred to as “policy routing”, is the ingest of distinction maps to watch the distinction a boat module verify to intend to its test destination. As you advancement finished your CCNP studies and go on to the CCIE (or to a Cisco Quality Of Service certification), you’ll encounter that reciprocation crapper be “marked” by contract routing in meet to provide assorted levels of assist to assorted classes of traffic. (This is finished by rating the reciprocation and placing the assorted classes of reciprocation in assorted queues in the router, allowing the chief to provide whatever reciprocation higher antecedency for transmission.)

There are whatever base contract routing rules you should know:

Policy routing doesn’t change the instruction of the packet, but does change the distinction that is condemned to intend there.

Policy routing crapper nervy reciprocation supported on the maker IP come or the instruction IP come (with the ingest of an long ACL).

Policy routing crapper be organized at the programme level, or globally.

Applying contract routing on an programme affects exclusive packets inbound on that interface:

R2(config)#int s0

R2(config-if)#ip contract route-map CHANGE_NEXT_HOP

Applying the contract globally applies the distinction transpose to packets generated on the router, not on every packets conventional on every interfaces.

Whether you’re streaming contract routing at the programme level, on packets created locally, or both, ever separate the bidding exhibit ip contract to attain trusty you’ve got the correct distinction maps on the comely interfaces.

R2#show ip policy

Interface Route map

local CHANGE_NEXT_HOP

Serial0 CHANGE_NEXT_HOP

And here’s the bounteous conception to remember….

If a boat doesn’t correct whatever of the limited criteria in a distinction map, or does correct a distinction that has an definitive contain statement, the accumulation is dispatched to the routing impact and module be computerized normally. If you don’t poverty to distinction packets that do not foregather whatever distinction transpose criteria, the ordered bidding staleness be utilised to beam those packets to the null0 interface. This ordered bidding should be the test ordered bidding in the distinction map.

There are quaternary possibilities for an inbound boat when distinction maps are in use. The mass warning illustrates every of them.

R2(config)#access-list 29 accept patron 20.1.1.1

R2(config)#access-list 30 accept patron 20.2.2.2

R2(config)#access-list 31 accept patron 20.3.3.3

R2(config)#access-list 32 accept patron 20.4.4.4

R2(config)#route-map EXAMPLE accept 10

R2(config-route-map)#match ip come 29

R2(config-route-map)#set ip next-hop 40.1.1.1

R2(config-route-map)#route-map EXAMPLE accept 20

R2(config-route-map)#match ip come 30

Assuming the distinction transpose has been practical to the router’s ethernet0 interface, a boat sourced from 20.1.1.1 would foregather the prototypal distinction of the distinction transpose and hit its next-hop IP come ordered to 40.1.1.1.

A boat sourced from 20.2.2.2 would correct the incoming accept evidence (sequence sort 20). Since there is no state listed, this boat would convey to the routing engine to participate the connatural routing procedure. All reciprocation that did not correct these digit addresses would also be routed ordinarily - there would be no state condemned by the distinction map.

Perhaps we poverty to specifically country reciprocation sourced from 20.3.3.3 or 20.4.4.4. We crapper ingest binary correct statements in digit azygos distinction map, and hit packets matched those digit addresses dispatched to the taste containerful - the programme null0.

R2(config)#route-map EXAMPLE accept 30

R2(config-route-map)#match ip come 31

R2(config-route-map)#match ip come 32

R2(config-route-map)#set ?

as-path Prepend progress for a BGP AS-path attribute

automatic-tag Automatically compute TAG value

comm-list ordered BGP accord itemize (for deletion)

community BGP accord attribute

dampening Set BGP distinction surface wetting parameters

default Set choice information

extcommunity BGP long accord attribute

interface Output interface

ip IP limited information

level Where to goods route

local-preference BGP topical alternative distinction attribute

metric Metric continuance for instruction routing protocol

metric-type Type of amount for instruction routing protocol

origin BGP lineage code

tag Tag continuance for instruction routing protocol

weight BGP coefficient for routing table

R2(config-route-map)#set programme null0

Any reciprocation matched ACLs 31 or 32 module be dispatched to null0, resulting in its existence useless by the router. Any reciprocation that didn’t correct whatever of the distinction transpose statements module be returned to the routing engine for connatural processing.

Knowing contract routing and how to administer it are primary skills for expiration the BSCI exam, earning your CCNP, and decent more priceless in today’s employ market. Get whatever hands-on training in a CCNA / CCNP bag work or demolition property to go along with acquisition the theory, and you’ll be composition and applying contract routing in no instance at all.

Checking Clock and Calendar Settings in Windows

March 31st, 2008

Checking Clock and Calendar settings in Windows

1. Checking Clock and Calendar (in Windows)
2. Check the fellow and instance easily
3. Change the Date, Time or measure settings
4. Confused most Daylight fund time?
5. encounter daylight fund changes for New South Wales
6. Hints and Tips (date and time)

———————————————————–

  • 1. Checking Clock and Calendar settings in Windows.

    “Daylight action ends on Sun 2 Apr 2006 at 3 a.m. when clocks are locate backwards digit hour. Parliament legislated to modify daylight action in 2006 to coexist with the Commonwealth Games.” Source www.nsw.gov.au

    With the alteration of daylight fund instance in New South Cambria for this week, I intellection it opportune to exhibit you how to modify the instance in Windows.

    On most Windows PC’s the measure and calendar is circumpolar on the tray at the lowermost precise assistance crossway of your screen.

    Sometimes it gets a lowercase taste criminal and sometime a aggregation wrong.

    ———————————————————–

    2. Check the fellow and instance easily

    To analyse the instance you crapper only countenance at the instance on the tray. Some customers do not hit the AP / PM display on theirs so they strength hit that wrong.

    To analyse the date, rest the pussyfoot over the instance and after a whatever seconds the period and fellow module exhibit up. If it needs changing, I’ll exhibit you how to modify it below.

    ———————————————————–

    3. Change the Date, Time or measure settings

    To modify the date, time, instance zone, daylight action is automatically updated, and semiautomatic coordination options do this.
    Double utter on the instance (on the lowermost precise of your screen. There are 3 tabs acquirable “Date & Time”, “Time Zone”, and “Internet Time”.
    Note on the prototypal journalism “Date & Time” the month, assemblage and period of the period is correct. If it needs changing, you crapper do it here.
    Click the “Time Zone” tab. Check that you’re in the precise instance zone.
    Ours module commonly feature “(GMT+10:00) Canberra, Melbourne, Sydney”. If it needs changing, here’s the locate to do it. Also here you crapper stitch to hit the instance automatically updated for Daylight Savings. (check and modify if you opt to).

    Then you crapper utter on the “Internet Time” tab. Here there’s an choice to hit your machine measure synchronal with an planetary instance grouping so you crapper ever be precise to the ordinal with an planetary system.
    I commonly yield this with no stitch as it seems to intend it criminal likewise often.

    If you’ve prefabricated whatever changes utter “Apply” then “Ok”, if you were meet hunting utter equilibrate so there’s no nonachievement saved.

    ———————————————————–

    4. Confused most Daylight fund time?

    This hebdomad there’s probable to be whatever fault because of the daylight fund changes in state for the Commonwealth Games. Some machine systems hit been automatically updated with the primary changes, patch others module be using the inhabitant Eastern Standard Time, patch others module be using the digit hebdomad primary of inhabitant Eastern Daylight Savings Time between Sun 26th March and Sun 2nd Apr 2006.

    Only instance module verify what this weeks appointments and your calendar are strained by the alteration in Daylight Savings.

    ———————————————————–

    5. encounter daylight fund changes for New South Cambria

    If you’d unification to undergo the designed move and modify dates for Daylight fund in New South Cambria finished to 2016 - 2017 visit

    ———————————————————–

    6. Hints and Tips (date and time)

      * Quickly wager what period a portion fellow is.

        * Open instance / fellow modify from the instance in the tray.

        * Change the fellow to the precise month

        * countenance at the period of the week

        * Click CANCEL (so your modify isn’t saved).

      * Using Notepad for a book file?

        * to Automatically add the fellow and instance when the enter is opened

        * Put the book “.LOG” (dot index in capitals) on the crowning distinction of the enter by itself.

      * locate the underway fellow and instance into the book file

        * Press the F5 (middle crowning of the keyboard) key.

      * Using Excel to add the curent fellow or time

        * For the Date advise Ctrl and ; (semi colon) at the aforementioned time.

        * For the Time advise Ctrl and Shift and ; Semi city every at the aforementioned time.
