Network address as the next hop address in ip route statement???
Hi All,
I am confused about ip route statements in the following Cisco document.
Configuring ISDN DDR with Dialer Profiles
Document ID: 9568
http://www.cisco.com/warp/public/793/access_dial/ddr_dialer_profile.html
The statements are;
ip route 172.22.0.0 255.255.0.0 172.22.80.0
ip route 172.22.80.0 255.255.255.0 Dialer1
Why does it use network address as next hop address on the first line?
And it is a source network address on the second line.
Please suggest me.
Thanks a lot,
Nitass
When you specify a network address as next hop in a ip route statement, the router does recursive lookup. When it matches a packet for a network other than 172.22.80.0, it will match the router 172.22.0.0 and the route basically says use 172.22.80.0 as the next hop. Now the router looks up the routing table for how to reach 172.22.80.0 and ends up routing via Dialer 1.

A.B.C.D IP address of next hopHi,
You may get your answer in below link
http://www.groupstudy.com/archives/ccielab/200812/msg00999.html
First next-hop will be used unless until that is not unreachable. If first is unreachable, then next one will be used. Since these next-hops are directly connected, router can easily come to know whether they are active or not. In case you want to set some loopback ip as next-hop then you need to use keyword recursive "set ip next-hop recursive"

The next-hop-self command PLEASE HELP
I have a question about the next hop-self command, i have a topology with 3 routers lets say R1,R2 and R3. Know R1 and R2 are Ebgps neighbors and R2 and R3 are iBgp neighbors. Know lets say i have a loop back address or lan on R3. Do i need to configure Next-hop-self on R2 towords R1 so R1 can ping R3s lans.
I need to be able to know the Logic very well so a clear explenation would be very appreciated.Sorry, you did say you wanted to understand the logic.
When a BGP router advertises a route to an EBGP peer the next hop in the route is itself. By definition the receiving router must know how to get to that next hop because they are peering with BGP.
When a BGP router receives a route from an EBGP peer if it advertises it to an IBGP peer by default it does not change the next hop IP so the next hop IP is that of the originating router.
So there is a good chance that the IBGP router does not know how to get to that next hop IP.
There are a couple of solutions to this and one of them is to configure the receiving EBGP router to change the next hop IP to itself which obviously the IBGP peer knows how to get because again it has a peering.

HT204053 Can I use an icloud email address as the primary email address for an Apple ID?
Hi There
Can I use an icloud email address as the primary email address for an Apple ID?Whenever you create a new icloud email it is an Apple ID, but if you previously had an Apple ID you cannot use the new email to replace the old one. You have to abandon the old accout and you will lose all the content you had with that account. But what I did was upload all my itunes to amazon cloud, these were the only purchases I had. I already bought books from kindle and I now rent movies from amazon instant video. Everytime I log in I use my icloud email and password. I just used it to sign in to support communities.
The notification that you posted about changing your Apple ID was present when I created my icloud email and made the change. -
After I updated user for i phone 4 s iCloud password is no way I can not phone and e-mail address has been blocked. I did not bring the solution to Turkey APPLE chief BILKOM is forgotten the password and e-mail address in the e-mail address asking for help from you I will make the iphone does not open e-mail address associated with it @hotmail.com mail to this address icloud iphone phone's password is forgotten, I want to thank you in advance for your help tell a method of opening up again.
<Email Edited by Host>Welcome to the Apple Community.
I have asked for your email address to be edited out. Posting your address in an open thread is a sure way to be bombarded by unwanted email, remember it will be here long after you have resolved your problem, for automated detection software to find.
If you want people to contact you, enable others to see your email address in your profile.
This feature has been introduced to make stolen phones useless to those that have stolen them.
However it can also arise when the user has changed their Apple ID details with Apple and not made the same changes to their iCloud account/Find My Phone on their device before upgrading to iOS 7.
The only solution is to change your Apple ID back to its previous state with Apple at My Apple ID, verify the changes, enter the password as requested on your device and then turn off "find my phone".
You should then change your Apple ID back to its current state, verify it once again, delete the iCloud account from your device and then log back in using your current Apple ID. Finally, turn "find my phone" back on once again.

forgot answers for security questions, my apple account has updated email address but the rescue email address for account is old and not accessible - do not know how to update that address so i can authorize new devices...
Welcome to the Apple Community.
Start here (change country if necessary) and navigate to 'Password and Security', reset your security questions using the link provided, you will receive an email to your rescue address, use the link in the email and reset your security questions.
If that doesn't help, you don't receive a reset email or you don't have a rescue address, you should contact AppleCare who will initially try to assist you with a reset email or if unsuccessful will pass you to the security team to reset your security questions for you.

PO Address for the Partner Order address.
Hi,
We have a problem with the address in the PO. We want to complete automatically the address from the partner Order address that has different address than the vendor.
So Vendor Number 1000 address in Madrid has the Partner Order address 1001 with address in Barcelona. We want to complete the address in the PO with the partner Order address from Barcelona. However the system always gets the address for the vendor in Madrid.
How can we do this process? The standard should be works like this. Otherwise we have to develop this procedure. But Are there any easy way by program to complete the address in the PO process or after that?
Thank you and best regards.the address from the OA partner is taken for the print out, where and why do you want to maintain it in the PO?

I have a set of 3 USB disks connected to my Time capsule (TC) via a USB hub. I usually switch the TC at night. When I restart the next day it stucks in amber state. When I disconnect the USB hub where my discs connects and restart, the TC will start properly. Any hints?
LOL.. don't switch off the TC.. this is fairly typical behaviour..
Or try a different usb hub.. but you could well and truly run out of hubs before you fix the problem.
Are you running latest firmware for your TC?
What error message is coming up in the airport utility.. amber led is a fault indicator.. look up what the actual fault is and see if it is for instance overloading the usb. You are using a powered hub??
Get one bigger USB hard disk instead of 3 smaller ones. -
Hello,
I want to change the address of next hop (router) so i can route the packet on my selective router.
I am capturing the packet using JPCAP. My gateway is my linux machine which is act like router.
Please help me its urgent.
Thanks in Advance
Uzair BaigHow you router packets is a feature of your operating system and your network configuration.
This is not a java question. I sugget you look at how you configure you netwokr router and your gateway. -
Another device on the network is using the same IP address
While this question has been asked within the community, I cannot find an answer that solves my problem. This happened about a year ago and was thought to be a modem/router issue. I switched to Airport and all had been fine until a few weeks ago. Now I periodically can't get online from my laptops.
Settings for my macbook at System Preferences ▹ Network ▹ Advanced ▹ TCP/IP are:
Configure IPv4: Using DHCP
IPv4 Address: 192.168.1.84
Subnet Mask: 255.255.255.0
Router: 192.168.1.254
Configure IPv6: Off
We did recently get a new ipad and new wireless printer so one of them may be the issue
Any help would be appreciated.
Thanks!If you are having IP addresses assigned using DHCP and one of the devices is disconnected from the network for a long enough period of time then the router will make that IP address available to another device to use. If the first device then comes back on the network with the same IP address it had before then you'll get the dual IP address situation. This usually doesn't happen since the returning device is SUPPOSED to ask for a new IP address when it re-joins the network. In your case this may not be happening.
What I do is use static IP addresses for all the devices on my home network. In your case I think this will fix your problem.
Set up your Airport to 'reserve' specific IP addresses for the devices in your local network via their MAC addresses.
Open the airport utility, select your router, click EDIT, select NETWORK.
In the area marked DHCP Reservations: click on the + sign
Type a description of the device.
Use the pull-down menu to select "Reserve Address By: MAC address"
enter the MAC address in the appropriate line.
enter in the unique IP address for each device that you want to reserve. Make sure its in the same subnet (ie. 192.168.xx.yy)
click SAVE
Repeat the above for all your devices.
Update your airport settings.
When you're done turn off all the wireless devices for 5 minutes and then reconnect. Each should then reconnect with the same IP address each time. You can still leave the devices themselves set to use DHCP so that when you take them outsider your network, they'll request an IP address from the new network.
I hope this made sense. If not, post back and I'll calrify anything you need. -
Next some advise... i've configured a VPN server -pptp on my router, create a vpn for client to site. At the moment, client computer can connect and established a connection to router. I can ping from client to router (192.168.5.1) but can't ping 192.168.5.2(switch) or 192.168.10.X (workstations)
What i'm trying to achieve is to access the internal network (192.168.10.X) which is from the layer 3 switch's end. Any help/extra eye would be good.
Here are my network design and config below:
Client Computer ---> Internet ---> (1.1.1.1) Cisco Router 881 (192.168.5.1) ---> Dell Powerconnect 6248 switch (192.168.5.2) --> Workstation(192.168.10.x)

exitHi Samuel,
I went through your configuration and picked up some problematic lines..
First of all you can't have your vpn-pool to be in the 192.168.10.x/24 range because you already have that subnet used behind the switch ( this would only be possible if you had 192.168.10.x range directly connected to the router ). Also, you can't bind your Virtual Template to the WAN ip, it should bind to a interface with a subnet that includes your vpn-pool IP range.
The cleanest way to do this is,
Create a new loop back interface with a new subnet
interface loopback 0
ip address 192.168.99.1 255.255.255.0
Have new vpn pool defined,
ip local pool defaultpool 192.168.99.200 192.168.99.210
Change your Template to point the new loopback interface,
interface Virtual-Template1
ip unnumbered loopback0
encapsulation ppp
peer default ip address pool defaultpool
ppp authentication chap ms-chap
All the vpn clients will get an IP from 192.168.99.200 192.168.99.210 range. And they will be able to get in to the router and up to the desired 192.168.10.x/24 range behind the router. Packets will get in to the switch and then in to the host. Host will reply through the gateway( switch ) -> router -> Client.
PS: Earlier, even if your packets get to the host, the host will never try to send the reply packets back through the gateway ( switch ) because from its(hosts) point of view, the packet came from the same Lan, so the host will just try to "arp" for the senders MAC and will eventually time out)
Hope this helps.

Address of the page in address bar
hi !
when one page is submitted to another page the name of the next page is shown on the address bar of the browser and i don't want it to happen so.
actually i want that when the next page is being downloaded then the address of that page is not shown in the address bar and i would be able to show a dummy address of that page in address bar.
coz in my site it is very essential that user doesn't know the address of the pages other then the login page.
but i don't have the idea to do this can anybody help me in this regard.
thanks in advance.no i just want to hide the address of my web page from the user and trick him by showing him a dummy addres,which if in future he uses to see the page then he cann't see it,because the address shown to him was dummy.

Sending email using Exchange 2013 defined email addresses not the account email address.
Currently we are using exchange 2013. Let's say a user has a mailbox account defined that has a default email reply address of [email protected] Now I define additional email address for the same account. When the user tries to send an email he can only send from
the default email address. Is it possible to send from a defined email anndress and not the default account email address?
Best Regards
Best RegardsNot natively with Exchange.
You will need 3rd party software if you want to have only one mailbox and the ability to send as any of the proxy addresses associated with it
Example:
