Cisco WAN :: 2811 DSL Load Balancing

Dec 9, 2010

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.

Cisco WAN :: ASR1001 / L2 Over L3 With Load-balancing?

Nov 30, 2011

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.

Cisco VPN :: Load Balancing ASA 5520

Sep 13, 2011

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 associated to it, and ASA2 has a VPN connection having IP address, how does the return traffic for each connection know which ASA to route back to?

Cisco Routers :: RV016 Is Not Load Balancing UDP?

Feb 22, 2012

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 ( ~ through WAN4, and all VoIP related traffic ( ~ through WAN2(PPPoE).Everything seems to be working well except for some of the UDP traffic from which is seen in the log going out of WAN4 instead of WAN2.I have even created a new entry for [UDP/5060~5060]->, 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> on eth4
Feb 23 18:11:46 2012     Connection Accepted     UDP> on ppp2
Feb 23 18:11:46 2012     Connection Accepted     UDP> on eth4
Feb 23 18:11:46 2012     Connection Accepted     UDP> 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 is seen going though WAN2 as it should.

Cisco WAN :: ASR1001 - Internet Load Balancing

Feb 3, 2013

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).

Cisco WAN :: 2821 / 881 - Load Balancing Between Two Routers?

Feb 24, 2011

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.

Cisco WAN :: ASR 1000 Multiple ISP Load Balancing?

Nov 21, 2012

I came up with a few ideas to Load Balance based on multiple ISPs. In our network setup we have a distribution layer of 3750s going to an ASR 1000 Series Router, which goes out to multiple ISPs, ISP1 and ISP2.
we also have a virtual fortinet appliance behind the 3750. If I say all traffic going to 0 - 126 goto ISP1, and 128 - 254 goto ISP2,and then obviously whatever NATd IP the customer has (ISP1 or ISP2), the return traffic will have to go to that specific IP. The traffic will allgo back to the virtual fortinet on the same interface, so I would assume I would be safe with uPF.I don't know of any ways to load balance based on Link Optimization, without implementing a load balancer?

Cisco Routers :: RV042 Load Balancing And OWA?

Mar 7, 2013

I bought one of these I am very disappointed by the management interface which is very limited/restricitve.I completely agree with Antonio here. In my case, most of my traffic is HTTPS sobinding https ports to a given WAN port makes the load balancing completely useless!!I also hope there will be a software update including the possibility to keep the session on the same WAN connection.

Cisco Application :: ACE20 Load Balancing

Apr 26, 2011

I have a problem with the ACE 20 load balance
To start with following is our architectural request flow:

Load Balancer --> Webseal /(reverse proxy) --> HTTP Server --> Portal Server

We have Hardware Load Balancer Cisco ACE20. When we access our portal from Webseal server it works totally fine without any issue, but when we access the same application using ACE we face the following issues:

1) Some of the links on do not work. For eg: We have a link "subscribe" which points to [URL], whenever we click on this link, the request is directed to [URL] i.e homepage

2) URL redirection does not work We have some links which have a url forwarding or redirection for example when we open [URL] it forwards the requests to [URL] opendocument....., but this redirection fails and again the request is thrown to homepage i.e., [URL]

3) The response of the request and the overall portal when accessed via ACE is very sluggish and it takes 20 seconds for homepage to load, whereas the homepage loads in 4 secs when accessed via webseal.

Below is the ACE details.

Hardware Product Number: ACE20-MOD-K9  Card Index:     207  Hardware Rev:   2.3  Feature Bits:   0000 0002  Slot No. :      7  Type:           ACE
Software  loader:    Version 12.2[120]  system:    Version A2(1.4) [build 3.0(0)A2(1.4) adbuild_11:54:12-2009/03/05_/auto/adbu-rel2/rel_a2_1_4_throttle/REL_3_0_0_A2_1_4]  system image file: [LCP] disk0:c6ace-t1k9-mz.A2_1_4.bin  installed license: ACE-SEC-LIC-K9

Cisco Security :: Load Balancing With ASA5510

Aug 29, 2011

We have an ASA5510 with two ADSL lines connected and the auto fail-over set up - this is all tested and if the main line fails, the backup line is used in it's place - no problem there.
However, I'd like to increase our connection speed, and one way I've done this in the past is to add a couple of extra ADSL lines to a router that is capable of load balancing.
I'm aware that the ASA5510 does not load balance (seems a waste as we've got the backup line just sitting there doing nothing!), but would it be feasible to add another router in front of the ASA device to perform this load balancing function?

Cisco WAN :: 2911 - Load Balancing Amongst 4 Links

Dec 19, 2011

I'm workig with a friend on a project. The setup in place is on yacht that has 4 V-Sats and they are wanting to load balance across all four of these links via a Cisco 2911. My recommendation to him was to just create 4 static default routes to each V-SAT's ip address.

Would this accomplish the goal of load balancing? My concern is that would it actually load balance amongst the 4 links or just choose one and then move other to another link once the initial primary went down? Also would enabling CEF be an option if its a feature the 2911 can do? I've attached the visio to give a better idea.

Cisco WAN :: Load Balancing Over L3 Etherchannel With 3750G

May 18, 2011

Here's the proposed network I have to work with:  LAN A >> ASA Cluster >> 2x3750G Stack >> Cross-stack L3 Etherchannel (2x100Mb Circuits) >> 2x3750G Stack >> ASA Cluster >> LAN B  Company policy governs that traffic between LAN A and LAN B must now be encrypted. ASA Firewalls have been purchased in advance and will be place into the network as above.   Src-dst-ip load-balancing is currently in place on the Layer-3 Eherchannel.  How can I encrypt the traffic using the ASAs and still ensure proper load-balancing over the circuits?  I was about to configure a IPSec/GRE Tunnel between the ASA Clusters but I'm concerned that the tunnel will not be load-balanced over the ether channel based on the single source and destination IPs I will need to configure.

Cisco WAN :: Load Balancing OER With 1841 Router

I went through an article which tells me of the configuration part however It only has 1 default route . In a case where that ISP goes down all traffic will be moved to other ISP link but there is no static default route for that ISP . Following is the article Link
Also is this the same type of technique other vendors including Baracuda , Tp-link etc work on Internet load balancing ?
