Cisco WAN :: AS 65100 - Change Local Preference For A Specific Network
Oct 12, 2012
As you can see at the picture below i have 2 routers connected via two fastethernet links. Both routers running BGP. R1 (AS 65100) and R2 (AS65000).
R1 got a loopback interface with the IP address 1.1.1.1 255.255.255.255 R2 got two loopback interfaces 2.2.2.2 255.255.255.255 and 3.3.3.3 255.255.255.255.
Let's say that i want the host 3.3.3.3 to go over fa0/1 to reach 1.1.1.1 and rest of the network to go through fa0/0. What can I do to make this possible?
I know how to set Local Preference on an interface... but then all networks will take that specific path.
route-map LP_FA0/1 permit 10 set local-preference 200 neighbor 192.168.2.1 route-map LP_FA0/1 in

I am currently looking to upgrade and extend my home network with preference to dual band and gigabit functionality. My problem is choosing the correct hardware.I want dual band to separate the network for the kids (a PC, laptop, Xbox 360 and phones all wireless) and set up parental controls and maintain connection speeds etc. For my needs I need the network to be connected to my Onkyo AV Amp (for internet radio and music streaming only), Blu-ray Player, Sky HD satellite box (all wired) and a PS3 (pref wired) and a few wireless devices all N capable. Apart from the obvious gaming capability I would like to be able to stream HD video to the PS3, PC (wired) and laptops via a USB HDD connected for now on an access point or modem router to save on the cost of having separate networked devices.
I currently have ADSL so I was looking to get a dual band gigabit modem router to serve the kids wireless hardware whilst my current hardware is on another floor and is connected with a wire from the existing modem but I have to keep swapping it from PS3 to amp etc.In short I am hoping to have a gigabit, dual band ADSL modem router and connect to a gigabit access point (with dual band if possible) via the cable I have sent to the other floor to wire up the 4 devices. I've currently been looking at Netgear and Buffalo solutions as I've had problems with Linksys and Belkin routers in the past. Would this be possible with just 2 devices (modem router and access point) whilst maintaining decent speeds and if so can someone shed some light as to what I should get.

One of our servers recently lost its outbout network connectivity. It can ping and communiate with any computer on our LAN, but it can't communicate with anything outside our network. It has a statically asigned IP address, and can ping the default gateway. We haven't changed any settings on the firewall or gateway....

Is there a way to force a specific speed for the local ports? I'd prefer not to rely on the autonegotiation.

I have a customer with a primary datacenter and DR datacenter, that has a P2P 100Mbps link connection between them. At the primary Datacenter there will be a Nexus 5596U with a L3 card running EIGRP, it will have three connections, one nothbound to the Internet not a problem, the other is north bound to an MPLS SP managed ISR router. Both datacenters will have MPLS SP managed ISR router, the MPLS service provider will be redistributing BGP into EIGRP from their ISR routers at both datacenters. This means we will learn external EIGRP routes with an AD of 170.
Connected to my 5596 southbound will be the SAN for the EMC storage traffic, the DR also has a SAN with EMC storage as well. The 100Mbps P2P link is primarily for replication traffic.
Since the Nexus 5596U with L3 module doesn't support PBR I have to figure a way for replication traffic to prefer the 100Mbps P2P link vs the MPLS cloud. I was thinking of running iBGP over the P2P link with the Nexus 5596 being a route reflector and it's iBGP peer which will be a Catalyst 3750X at the other end of the P2P link being the route-reflector client. That way both iBGP peers will exchanged learned routes.
I have to come up with a way for the replication traffic that comes sourced from the IP addresses of the EMC/storage to prefer the P2P link which will have an AD of 200 from iBGP in the routing table vs the external EIGRP traffic that has an AD of 170 in the routing table. All other traffic will route normally across the MPLS cloud. All other traffic will include client server traffic as there are application servers that sit south bound of the Nexus 5596, the client traffic will come inbound to the datacenter via the MPLS cloud.
I don't have a Nexus 5596 to do a mock lab. My thought is to redistributed connected with a route-map in EIGRP on the Nexus 5596 with a two match statements then set the IP next hop to the IP of the 3750X. I would need to select only replication traffic, so I was thinking if I can match on vlan and next-hop then my set command would be the next-hop of the 3750X.

I was in the process of creating a AAA setup on my NX-0S (MDS9148), logged out/attempted to login to test AAA login and now I can no longer login as admin either! I didn't change the local account. I have the Cisco Device Manager open still (in the fabric switch) and how I remedy this (AAA is not up and running as of yet with this switch).

I have a problem on my catalyst 6509 on which I would like to do the following things :
I have some Vlans in which multicast is enabled.
In tose Vlan theres is a router which is default router for equipements.
I had enabled multicast routing because some Vlan needs to exchange multicast informations, but I wolud like to make difference between Multicast traffic. For example I have 5 vlans:
Vlan 1 and 2 need to exchange Multicast informations but the don't need multicast information from Vlan 3 and 4
Vlan 3 and 5 need to exchange Multicast informations but the don't need multicast information from Vlan 1 and 2
Vlan 5 is independant Vlan but doesn't need to have multicast information from all others vlan.
Last problem, equipement on differents vlan can use the same Mulkticast group address. In this case, Multicast routing is not working between Vlan 1 to Vlan 2 and Vlan 3 to Vlan 4.

ASA 5520 running 8.0.4
ASDM v.6.1
Need assistance understanding how in ASDM/Configuration/Site-to-Site VPN/Connection Profiles/ "Any Entry" I can specify that I only want to offer an IKE Proposal of pre-share-aes-256-sha?
The IKE Proposal field has a number of possible options including: pre-share-aes-256-md5, pre-share-3des-md5, pre-share-aes-256-sha, pre-share-aes-192-sha, pre-share-3des-md5, pre-share-aes-sha and pre-share-3des-sha.
I am able to pick a specific IPSec Proposal w/o issue but when I attempt to do the same for the IKE Proposal, and click OK the choice does not "stick" but rather returns to the entire list as defined above.

Is it possible to enable an absolute value rate limit using QOS on a HP ProCurve 5406 switch for a particular IP range on a specific port? Is there a way to configure our HP 5406 with an absolute rate limit on "WAN" port for that server's IP range? I would like to limit it to only being capable of sending 1Mbps worth of traffic over the head end at once.Everything in the documentation points towards priority queues, which as far as I can tell, isn't really what I want.Baring accomplishing this goal using rate limiting is there a better way to prevent our services from accidentally saturating this connection?i thimkong about somthing like that:
class ipv4 rate-limit-port-A1
match ip 10.136.0.0/16 any
exit
policy qos port-a1-ratelimit
class servers-to-be-slowed action rate-limit kbps 1000
exit
interface A1 service-policy port-a1-ratelimit inI'm not sure about this.

ip dhcp excluded-address 192.168.1.192 192.168.1.254
!
[code]....
I want to assign a specific IP to a specifig host by MAC .. for example i want the ip 192.168.1.10 to be assign to the host "client1" by mac.I've been creating a new dhcp pool static:
!
ip dhcp pool static
host 192.168.1.10 255.255.255.0
hardware-address xxxx.xxxx.xxxx
client-name client1

After not using my computer for a week due to illness I've turned it on to discover that it cannot connect to the wifi network that has been working fine for the last few months. The network is shared and I don't personally have access to the router, and the network administrator is away at the moment so I can only attempt solutions at my end.It seems it might be an IP configuration issue. Network diagnostics gave me the error message "Wireless Network Connection 4 doesn't have a valid IP configuration", as well as one or two other IP-themed error messages.
My computer thinks it's connected. It says I'm connected to the network and that I have internet access, but there's no actual connectivity.Finally, weirdly, I did seem to manage to connect briefly at one point. It took about three minutes to load the Google homepage and then dropped again. I have no idea what the significance if any of that is.I know the following for sure:
- the wifi network does work; I'm using it on my laptop right now
- the network adapter on my computer also works, it can connect to the wifi hotspot on my phone

Using my current network, I am unable to connect to [URL].It doesn't matter what browser I use or if I use a cli-command (wget, curl).
Error in Google Chrome:
Oops! Google Chrome could not connect to [URL]
Error using curl:
curl: (7) couldn't connect to host
If I use nslookup to get the IP-address of YouTube, I get 173.194.32.32.If I go to http://173.194.32.32/ in my browser it can connect, but as Google is probably checking the Host HTTP-header, it shows Google's frontpage instead.
There is no blocked websites on the router and other devices on the network seems to work.My computer only has this problem on this specific network.
I am using Mac OS X 10.8.2 on a MacBook (mid 2009).

I'm just new with ASA. I'm just self-studying on it. I was tasked to have an ACL that will allow inside hosts to access a specific network. Is there a way on how to know all the inside hosts on the behind ASA so that I can do a "object-group network" on those inside hosts which I think it will look neat.

I was trying to configure a friend's router, but their laptop wouldn't connect wirelessly. Initially, I couldn't connect via ethernet cable either, but I went into the settings and set it to obtain an IP address automatically. After that, I could connect via ethernet no problem.I was able to successfully connect wirelessly on two different mobile phones.I still can't connect wirelessly to this router (well, technically it says it's connected to the network, but it won't connect to the internet, nor can I bring up the hub settings). However, I can connect to their old router no problem. I'm not sure whether the problem lies with the laptop or the router, and don't presently have another laptop to check

My USB wireless adapter does not detect one specific network anymore on my laptop (toshiba). It was detecting it until a while ago, and all of a sudden I cannot see the network anymore. However, when i connect the wireless adapter to my other laptop (lenovo), the network is detected. Nothing has changed in the wireless network, and no programs were installed on my laptop (toshiba) before the network stopped appearing.

my laptop, which connects fine to all other wireless networks, has trouble on this one. It can browse the web all day, but the second a large file begins to transfer (video, a file download, etc.) it will drop the connection randomly, usually rather quickly. The computer does not need to be restarted to reconnect, it often reconnects on its own near-immediately, though sometimes I have to go to the system tray and reconnect manually.I thought it was too far from the router, but my tower in the same room connects flawlessly, and going in to the same room as the router doesn't work. This same laptop has been fine on every other network, and every other computer is fine on this network. I've web crawled off and on about this for months, but no one's problem is limited to one computer/network combination.

I want to setup a DC++ HUB for sharing data within the university local network. We have addresses of the form 172.31.*.*. These addressed are accessible within the university bu non routable outside on the internet. My plan is to setup a local HUB for DC++ for sharing data within the university intranet. So even if internet is unavailable data can be exchanged through LAN. This HUB must not be accessable outsied the university network.how should I do this all..implementing network sharing other than DC++. My basic idea is that everybody can share their data and the data is searchable from one common interface( Web interface is better option, if possible). And data featching should prefferably be from many hosts, using multiple connections so that speed can be improved..

I have a home network running all Mac computers (though can run Windows VM if necessary) and a pair of USB printers. The wireless router and cable modem are in one room, but the printers are in another. I'd like to find the most practical way to add the printers to the local wireless network without sharing them from a computer. I've tried that for a while, but don't want to leave a laptop connected 24/7 just to enable wireless printing (rather defeats the purpose of a portable computer). I don't have any wired network lines in the home, and am not excited by the idea of running any cables.

I provide support for a small business network. ISP: Silo Wireless (wireless point to point with ISP) Router: Cisco RV220W Wireless-N Network Security Firewall
The router is configured with two wireless access points with SSIDs: "abracadabra" and "abracadabra-guest". The only difference between these two wireless networks is their passcode. Up until now I have had no problem connecting devices to either wireless network.
My problem lies with an HP Pavilion laptop running Windows Vista Home Premium 32-bit that I'm trying to connect to the "abracadabra" wireless network.
Network and Sharing Center shows "Identifying" for a while and then shows "Unidentified network" with no local or internet access. Wireless network connection status says that Media State is Enabled, Speed is 54Mbps and Signal Quality is Excellent. Network Connection Details shows that DHCP is Enabled but it's getting an Autoconfiguration IPv4 address of 169.254.107.138...
The laptop is running ESET Nod 32 Antivirus 5 and Windows Firewall and I've disabled Windows Firewall on the Wireless Network Connection. I've also tried re-installing the wireless nic driver, it's running the latest from Windows Updates.
what really gets me is that the laptop can connect to "abracadabra-guest" fine and access the internet

There is a device which is connected to the PC via Lan. I have an exe file which is supposed to get connected to that device and perform some operations. However, the problem is, the exe file tries to connect to the local host ip address 127.0.0.1 and i cant change the ip since it's been coded.So, I'm wondering if i can use the device connection (which already has a different ip like 169....) as a local host connection. So whenever it tries to connect to the loopback 127... it automatically connects to the external device.

I am planning to deploy a "Digital Notice Board system" in my office, which gets feed from web server and display data/stream on LCD Screen. Well i am done with implementing all the interface on server side and its working pretty well with client side computer. But instead of using Client Side Computer, I just want to use LCD and make some network interface of Local Area Network directly with LCD (to save cost/installation/maintenance of a dedicated computer with LCD ).

i purchased vaio with win8. Under network icon, I can not see any other computers in the local network therefore not able to access shares unless i explicitly map the shares which is tedious.
On other computers running win7 and xp, each of them can see each other under network icon.However that is not the case with my laptop running 8. Actually i have seen once or twice all pc-s show up but most of the time, they dont appear.
I read somewhere that following service need to be checked to make sure they are running: upnp, ssdp in services. I checked those and they are all running.
I also enabled "turn on network discovery" under network and sharing->advanced sharing. setting. To make it more complicated there are private and public and all network setting. I enabled all items as follows:
1. Private Turn on network discovery is checked along with Turn on automatic setup of network connected devices Turn on file and printer sharing is selected Allow Windows to manage homegroup connections is selected.
2. Guest or public Turn on network discovery is selected Turn on file and printer sharing is selected.
With these settings I still dont see the local computers and their shares. Do I need to check anything else?

I have a 5540, and i am trying to allow access to internet for an specific network object group, who has inside a bunch of users, who needs direct internet access without any restrictions, i have tried with dynamic NAT, but that configuration ask for a specific IP o a Network range, and is not permitted to configure an object group as a source
The group is located in LAN zone, so a permission from one zone to another zone is needed i think, but i can allow the internet acess to that group Is there another way to get that , different from NAT ?
