DQ77BK - Hardware To Do Load Balancing / Failover With 2 Internet Connections?
Nov 29, 2012
I am going to use a DQ77BK motherboard, which does "dual band" LAN. I have been told that with this, i can use two internet connections (from two different providers), so that when one fails, my computer still uses the other one. As you have understood, i need to be safetly connected to internet. I cannot have internet switched off in the middle of my work.
So, what do i need to do this ?
- Do i need 2 wifi cards, or would 1 "dual band" wifi card (like the Intel centrino 6200) be enough to handle it ?
- Do i need two antennas ?

I have DS3's to two different providers. Each is hosted on its own 7206. The 7206's are connected to each other and both connections to the internet route traffic in and out just fine. Failover between the two is working as well. The issue I have is that one DS3 is used more than the other because it has the best route to most of our remote offices. I wanted to see if theres a way to make one of my routers posess a more attractive route to a given subnet. Of course, in the event of a router or provider failure, I would want the other router to start routing the traffic for that office.

We are looking at purchasing and RV042 soon and have one cruitcial question. I am looking at having two internet connections running into the RV042. The only load balancing is going to be that all the VOIP traffic will go through one connection (eg WAN2) and then have all other traffic (such as web and email) through WAN1.
I am looking to have it so that if one of the internet connections goes down then it will failover EVERYTHING to the one that is working so both the VOIP and all the other traffic share the same connection until both WANs then go back online.

We have purchased a Cisco 1921 with twin ADSL after advice from a Cisco sales rep. However I am having trouble working out the load balancing/fail over config for the device.
I would like traffic to balance over both ADSL lines and if one goes down not to interrupt connectivity.
I had a look at ppp multilink but I am unsure our ISP (BT) support this?

1) 2 x ASA 5520, running 8.2
2) Both ASA are in same outside and inside interface broadcast domains – common Ethernet on interfaces
3) Both ASA are running single context but are active/standby failovers of each other. There are no more ASA’s in the equation. Just these 2. NOTE: this is not a Active/Active failover configuration. This is simply a 1-context active/standby configuration.
4) I want to share VPN load among two devices and retain active/standby failover functionality. Can I use VPN load balancing feature?
Active/Active failover is understood to mean only two ASA running multi-contexts. Context 1 is active on ASA1 Context 2 is active on ASA2. They are sharing failover information. Active/Active does not mean two independently configured ASA devices, which do not share failover communication, but do VPN load balancing. It is clear that this latter scenario will work and that both ASA are active, but they are not in the Active/Active configuration definition. Some people are calling VPN load balancing on two unique ASA’s “active/active”, but it is not
The other confusing thing I have seen is that VPN config guide for VPN load balancing mentions configuring separate IP address pools on the VPN devices, so that clients on ASA1 do not have IP address overlap with clients on ASA2. When you configure ip address pool on active ASA1, this gets replicated to standby ASA2. In other words, you cannot have two unique IP address pools on a ASA Active/Standby cluster. I guess I could draw addresses from external DHCP server, and then do some kind of routing. Perhaps this will work?

One of our customer has 3 ISP Line, out of which Two are Broadband and One is Leased Line. All 3 ISP interfaces are Etherent.
Now, they want Auto Failover with Load balancing among these 3 ISP lines.
Can we do same implementation in Cisco 1941 Router?? What licenses required in router for same?

I've a network with 28 computers and 2 servers. Each server have a double Gbit port configured in Load Balancing & Fail Over.Now, I want to buy two Cisco's Switch SG 200-26 and I would know the best way to connect them and if it's possible to interconnect them with more than one cable to share the trafic.
1. Is this following solution a good one (does the link between swhitches will work when computers will access to servers) ?
2. Is this next solution possible ?

We have a RV016 load balancing between two broadband WAN connections. On protocols that are sensitive to a change in IP address such as ssh and https, if the client connection goes inactive for a short time (sometimes as short as 10 seconds), the RV016 often changes WAN connection as part of its "load balancing" feature. Most protocols do not even notice, but the more sensitive protocols do and often lock a session or timeout the session which is not a good thing.
We have been able to bind these sensitive protcolols to a particular WAN port but (in our minds) this is not an "ideal" situation. In fact I would consider this to be a broken "load balancing" solution and should be fixed.

I want to load balance my Internet traffic between two ASR 1001 routers that are connected to our core switches. Both routers are connected to the same ISP (Comcast) going to the same BGP AS on different /30 subnets. Is there a way for me to load balance my Internet traffic using both connections with BGP rather than having one of these connections sitting idle? If not, the only solution I see is to configure my layer 3 devices to split internet traffic between both routers (i.e. default routes with same AD).

We use Cisco ASA 5520 (in HA configuration) connected to Cisco Switch 3750, ISP connection (25 Mbps) is straight to cisco 3750 switch. Since, Internet traffic is now high, a seecond ISP will be added.Our plan is to do Internet Link Load Balancing. My understanding that AS5520 can not do balancing.What appliance do you think I can use to accomplish the link balance?Also, take in consideration that our current ASA is also our VPN server and there are two DMZ zones.

We have deploy a Cisco ISR 2921 to connect two ISP for internet access, Link 1 is fix public IP, link 2 is xDSL.And we configure dual link load-balance, the configure just like the famous DOC "[URL]" name:"dual internet links NATing with PBR and IP SLA". Inside network to internet is ok, and traffic was load-balance, Dual link can be redundancy. But there has some issue we don't realize.Most people interesting how the inside traffic load-balance outside, but ignore the traffic from outside issue.

configure a router 1812 as failover, I walk with fixed ip internet link in Fe0 (need to determine the mac) and a dynamic ip link in FE1, other ports with a single vlan dhcp 172.20.16.1
I managed to do DHCP, connect to internet, to make nat vlan. But I could not do failover and load balance neither.

i'm trying to accomplish the following:I want to trasport a bunch of vlan layer 2 etherchannel on a pair of layer3 connections, using L3 to load balance.i was considering a pair of options:
1) bridging + gre (non applicable since i cant bridge 2 interface beloging to a etherchannel to a tunnel)
2) L2TP is it possible to accomplish this with the above tecnology? any reference, configuration example?
3) AoMLPS is it possible to accomplish this with the above tecnology ? any reference, configuration example?
I cant modify topology, the routers used are ASR1001 It is mandatory that both sites have a layer2 connection between them.

I have a Cisco 2811 router with two HWIC-ADSL cards configured for dsl connection. I have two lines from the same ISP and i am load balancing between them. I have created a couple of SLA's to check the state of the connections and add to the routing table the two default routes if both are up or any one of them is up.My problem is that when i try to download big files (especially antivirus updates) the download at some point stops (especially the antivirus exits with an error of unreachability). If i shut down one line everything works fine.Could i use something (configuration-wise) to prevent this problem from happening?????Is there any way i can combine the two lines? They are simple ADSL connctions with static ip's.

I need to configure DSL Load Balancing on Core Cisco Switch 4506-E. I have a Router Cisco 2811 with 2GE Ports and a Firewall Cisco ASA5505. I have 8 Physical DSL Connections with 1Mb each. I need to combine that 8 Mb on Core Switch and allow each end user to access the Internet via the available DSL connection which means that every user has 8 Mb available.

We have an ASA5520 pair that we will be installing to load balance SSLVPN connections. Below is a portion of our configs pertaining to the VPN load-balancing feature (configured on both ASAs):My specific question is related to routing of return traffic to load-balanced VPN sessions. Is there some kind of persistence function that tells the return traffic which ASA to route back to? For instance, if ASA1 has a VPN connection having IP address 10.211.112.1 associated to it, and ASA2 has a VPN connection having IP address 10.211.112.100, how does the return traffic for each connection know which ASA to route back to?

Friend of mine has a setup out in the sticks, currently with two ISPs: Hughesnet satellite, and a line-of-sight WiFi provider; they're also getting a cel tower within range soon and he's looking at adding an HSPA/LTE connection via that as well.the first gives him a static IP and ridiculous speed and bandwidth at night... but far less speed and a painfully low bandwidth cap during the day (you go over, you pay through the nose).
The second gives lots of bandwidth but poor speeds (difficult to even watch a YouTube video) and a constantly-changing dynamic IP.The third, once implemented, will give him good speeds and decent bandwidth (I believe up to 10GB/mo) but again, will get spendy if he goes over that limit.Right now, I've got him set up with both routers plugged into the same network, multi-homed the NICs on his machines (192.168.0.* for Hughes, 192.168.1.* for LOS) and a little script on each computer that will change the default gateway to let him select which ISP he wants to use... however, it's going to get trickier with a third, and will make it even tougher to keep track of the bandwidth used on each one... especially with multiple computers, a DVR, and two users.
So I'm looking for some way to automate all this... something that will, say, use the HSPA feed most of the time for his whole home network, switch to LOS if it gets near the cap, and switch everything over to the satellite automatically during "unlimited" hours. Again, I'm not opposed to setting up something PC-based with the appropriate software, although for my own sanity, it would really need to be Windows-based (I'm way below n00b with Linux).

We have Cisco CSS 11501 and connected in One-Arm way.Currently there are 4 source sending traffic and 3 server to receive the request. We are using Advance-balancing with Source IP. So the ratio become 2:1:1 or 1:2:1 or 1:1:2.But our target is to do the load balancing in equal ratio.

this router (RV016v3, Firmware: v4.1.1.01-sp (Dec 6 2011 20:03:18)) in regards to it not properly directing UDP packets out of the right WAN, as per the settings stored in Protocol Binding section of [System Management, Multi-WAN].I use the section to direct all traffic from desktop computers (192.168.5.100 ~ 192.168.5.199) through WAN4, and all VoIP related traffic (192.168.5.200 ~ 192.168.5.239) through WAN2(PPPoE).Everything seems to be working well except for some of the UDP traffic from 192.168.5.200 which is seen in the log going out of WAN4 instead of WAN2.I have even created a new entry for [UDP/5060~5060]->192.168.5.200~192.168.5.200(0.0.0.0~255.255.255.255)WAN2, and placed it at the very top of the list.Here are a few lines that I've observed in the log: (Refreshed the registration of two SIP Trunks configured in our PBX)
Feb 23 18:11:47 2012 Connection Accepted UDP 192.168.5.200:5060->184.72.227.214:5060 on eth4
Feb 23 18:11:46 2012 Connection Accepted UDP 192.168.5.200:5060->50.56.59.168:5060 on ppp2
Feb 23 18:11:46 2012 Connection Accepted UDP 192.168.5.200:5060->184.72.227.214:5060 on eth4
Feb 23 18:11:46 2012 Connection Accepted UDP 192.168.5.200:5060->50.56.59.168:5060 on ppp2
There are no static routes configured, so i'm baffled by what could cause some of the UDP packets to go through the wrong WAN.All TCP Traffic from 192.168.5.200 is seen going though WAN2 as it should.

We have a network topology like 2821 router with MPLS link and 881 Router with DSL Connection(DMVPN).
MPLS Link runs in BGP
DSL Connection runs in EIGRP.
So the existing scenario is like When ever MPLS link goes down Traffic will be moved to DSL connection. and once it come again it will be moved back to DSL using HSRP we are doing this. in this case most of the times my DSL connection will be in standby mode.Now my management decided to use both the links in active state and want to do some load balance between the links for some specific traffic like Internet, WSUS Updates, Antivirus updates need to go through the DSL connection even the MPLS is up and running.

I have a rv042 router with two internet connections. I have setp the WAN1 and WAN2 and set the load balance mode. Surfing on internet is then not a problem and I checked that I was using the two internet connection.However if I try to connect to my corporate (OWA) outlook web access i am looping on the first page where I should provide my credentials.I know that most of the load balancer could be set up with a sticky bit to keep the session on the same WAN connection.

confirm is Per packet load balancing is supported in the 3560's ?
I am going around in circles, and can't find a definate Y or N answer.
I have a suspicion this CEF feature is only available on routers.
