Cisco WAN :: 5510 Dual ISP Load Balance And Backup For Each Other

Mar 4, 2011

I have two ISP circuits and the following devices in hand:

1.   Cisco ASA 5510
2.   Cisco 2800 router
3.   Cisco 3750 switch

I've finished a part of the configs on above equipments, please refer to the attached diagram.And I'm making a test in order to achieve the below features:

1. By default, packets from PC1 go out through ISP 1. Packets from PC2 go out through ISP 2
2. When ISP 1 is down, packets from PC1 changed its way to ISP 2 through the 2800 router. And when ISP 2 is down, Packets from PC2 changed its way to ISP 1 through ASA 5510.

Cisco Routers :: RV042 Link Backup Versus Load Balance?

Nov 14, 2011

We have 2 dsl lines coming in and the modem is in bridge mode while the router handles the pppoe information. Each line is 6mb down and .5 mb up. It's ****, yes I know, but this is pretty decent for a small town in the country. To double our bandwidth, I put it in load balance mode. When load balance, I get anywhere from 9-12 down and .8 up. Here's where it gets tricky.
 
When anything is uploaded, the speed drops from 9-12 down and .8 up to about .2-.7 down and .2 up. I realize that we will lose some down and up speed but I wouldn't think it would be this drastic. Is this normal?When they upload to a specific https site (file is about 50mb), it never initiates the upload. If I switch it to Link Backup, it will upload fine. I still lose the speed but at least it does something. I've read that some https sites have issues with grabbing data from multiple IP's so I figured this is the case since it's a medical site that was probably developed in house. Is this true?Does protocol binding work in Load Balance mode? I binded all http and https traffic through WAN 2 interface however, when I do a speed test or check my external IP, it is not indicating the WAN 2 IP address.  Is this a common issue in rv042's or is there a firmware update that solves all these issues?

Cisco Routers :: RV042 Dual-WAN Threshold Based Load Balance?

Sep 19, 2012

I have an RV042 (it's old, silver/dark grey plastic front one) w/ firmware 1.3.13.02-tm.
 
The reason we bought this (long ago) was to balance two WAN connections, one with unlimited data and one capped monthly.  It did that once, but for a couple years both connections have been unmetered so it's just been balancing them 50/50.  As of today one WAN connection (the new much faster one) is back to being metered but I can't figure out how to configure the RV042 as it once was to prefer sending traffic over the slow, unmetered connection first, and only use the faster metered connection when necessary.
 
It's been a long time and honestly I only vaguely remember the ability to prioritize a connection based on % of bandwidth used so that all traffic would go over the unlimited connection 1st until it was flooded, and only then fall over to the metered connection.  This is totally different than the weighted round robin, or smart link backup.
 
I found this 3rdparty forum post that supports that vauge memory and suggests this was eliminated between firmware 1.23 and 1.3: [URL] Is it possible to replicate this functionality with the current firmware? if so how?  If not, how to do roll back to firmware 1.23?
 
It sounded like perhaps I could assigned WAN1 a bandwidth of 100000 (even though it's really 1500) and then assign WAN2 a bandwidth of 1 (even though it's really 20000) and the result might be the prioritization I'm looking to achieve...  but I feel like I'm stumbling in the dark at the point.

Cisco :: Load Balance Between ASA And FWSM?

Aug 6, 2012

What is the best way to load balance traffic between an FWSM and ASA 5520? Both are attached to a 6509-E (in seperate VLANs). The problem is the FWSM doesn't support any dynamic routing protocols (in multi context mode). So with my limited knowledge I don't see a way to do this.

Cisco Routers :: RV042 VPN Vs Load Balance

Jun 6, 2011

I have problem with VPN and Load Balance at the same time.VPN (Gateway to Gateway) between two RV042 routers is working fine with only one WAN or two WAN's with Smart Link Backup. If i switch to Load Balance communication through VPN is almost impossible.
 
I have postgres server (port 5432) in first location and clients in another. Clients cannot connect to server or lose connection after while. This is example, but every communicaton except ICMP over VPN with Load Balance enabled is faulty (file sharing, RDP...). Everything works fine using public IP and port forwarding or VPN with only one WAN.
 
If i understand it correctly Protocol Binding should affect only "normal" communication (outside of VPN), but it looks like VPN communication is also divided between WAN1 and WAN2. Of course this cannot work this way because VPN works only with one WAN.

Another question - is it possible to bind communication TO selected target port with RV042 Load Balancing to selected WAN?

D-Link DSL 2640B - Does It Load Balance Bandwidth

Aug 30, 2011

I have a D-Link DSL 2640B on the way which I plan on using to replace my 2Wire modem. The 2640B is a combination of a modem/wireless device. Does it dynamically load balances the internet connection? Sometimes while I'm playing online games on my PC and a few others are using the internet for browsing or Youtube, I lag A LOT. Latency shoots up from 10 to 200. QoS goes to ****. And I only need 0.50-1Mbps to keep a steady online play. This was the problem with my 2Wire. So does the 2640B load balance the bandwidth?our max speed is 3.5Mbps according to the ATT Rep.

Cisco WAN :: Load Balance Of 3750 Port Channel?

What is the load balance method of 3750 port channel ( by source ip , or by source mac ) to diver traffic to paths? I have tried to use 10.242.104.101 and 10.242.104.102 as source ip, it will travel to the same link (G0/1) within one port channel (G0/1+G0/2). Howerver, if I later use 10.242.104.109, then this time it will traffic to G0/2 link. What's the concept behind.

--- I have 2 WLC's 5500 that I have to set up on my network with the same configuration except I am not sure that they can be load balanced.

--  My only thought is to take a full class C and on each WLC set up a /25, thus each device can provision 120 IP's

--- This seems a bit archaeic, but is there anything else smarter to do? Can they be load balanced?

Cisco Firewall :: ISA570 - Load Balance Between Two ISP Connection

Apr 24, 2013

We want to us an ISA570 and load balance between two isp connections, two of our switches will be standalones and not connected to one another.  One switch will be for data and another VOIP/Data. The ISA will also do NAT and we need to make sure that the VOIP network can get out to the first isp.  I assume we will need a static route for that to make sure it goes out the right isp.  I just don't know if routing mode needs to be enabled in order to specify a static route, because I heard you can't have NAT and do routing mode at the same time.

Cisco Routers :: Configured RV042 To Load Balance 2 WAN

Mar 16, 2013

I configured a RV042 to load balance 2 WANs. It appears to working well but I would like a 2nd opinion as to whether or not I chose the proper settings to accomplish the task.
 
1. WAN1(ISP1) is the existing internet connection(1.5mb T1). I have a block of static IPs with ISP1.
2. I added ISP2 to the RV042's WAN2 connection to increase bandwith (10mb). I only have one static IP on ISP2.
3. I want everyone on this router to use WAN2... well... almost everyone... for the most part.
4. I want to keep WAN1 active on this router because there will be periodic inbound connections using static IPs (from ISP1) that are setup with one-to-one NAT. I also have a voicemail system that needs to continue to use ISP1's email relay (SMTP,25).
 
Anyway, I was able get the outgoing traffic that had to remain on WAN1 working with protocol binding. In order to get the router to use WAN2 for pretty much everything else, I set it for load balancing and set "Max. Bandwidth provided by ISP"  for WAN1  up & down kbits/sec both to 32 (very low). I left the WAN2 up & down settings to the actual speed of WAN2.
 
The result is very low traffic on WAN1 and lots of traffic on WAN2 which is what I wanted. Did I do this right? Is there another preferred method to accomplish this.

Cisco Application :: ACE 4710 HTTPS Load Balance Configuration

Have two ACE 4710 in HA setup. We would like to setup HTTPS loadbalance(actually just a primary and standby configuration in the serverfarm). Initially this would be for Exchange OWA connections but may expand to more HTTPS connections later. I know there are several ways to do SSL with the ACE( client, server, end-to-end). I am just wanting to know the easiest way to deploy this? Is a certificate always needed on the ACE for each connection? In HA mode would a certificate be needed for both or does it replicate in some way to the other ACE?

I thought that maybe both interfaces would traffic about 450MB.Is there some wrong configuration with the load-balance command?. At this moment there is no load-balance, It is only configured the port channel with the default configuration.

Cisco WAN :: 1841 Unequal Load Balance With Static Routes

I have a 1841 router attached to 2 ISP's. Each ISPs provides different bandwithd. I want to do load balance between them, but I want to do some sort of weighted load blance, so as to assign more traffic to one ISP than the other. A kind of 70/30 (70% of traffic via ISP1, and 30% of traffic via ISP2).Is there a way to acomplish that? I already tried creating bogus /32 routes, but "cef" seems to be more clever and groups the bogus routes as one gw.

Cisco WAN :: 6513 / EIGRP Unequal Load Balance Calculations?

May 15, 2012

I have used EIGRP with the variance command for years.  Recently we swapped out our 6513 for 2 Nexus   7K's and lost the variance command.  So now I'm stuck running our two MPLS routers to a 3750 which then connects to the 7K's, so I can get the unequal load balancing back in operation.So because I can't play with it while it's in production I'm using dynamips to simulate the configs.  The problem is I'm not able to get a traffic share count ratio that reflects the actual difference in bandwidth. 
 
The two lines have 155 MB and 45 MB respectively, for a ratio of 3.4.  Now you can't really send ".4" of a packet but the total packet ratios when dividing the traffic share count should be similar.  I'd settle for 3.  I was able to get 2.9 in the past but now on the simulator I can't even get that.  I'm seeing traffic share counts like 120:89 and 120:71 depending on how I fudge the metrics when I inject the routes from BGP.
 
I found this link: [URL] a stellar article by the way, and this guy is doing calculations to arrive at a 5:1. BUT when I apply the same formula using specifics from my network and the desired ratio of 3:1 what I get is an AD so high that the route is no longer feasible.  I simply cannot make a ratio fo 3:1 using the formula. How to be able to make anything other than a marginal ratio actually work or is this all just theoretical?

Cisco WAN :: 2800 ISR And MPLS - How To Load Balance / Prioritize Traffic Between Them

Oct 31, 2011

We have 2mb mpls network between three sites. Each site also  has its own internet connection for hosting webserver and internal users to access internet. Each site has a few internal subnets. Each site currently has a  2800 series ISR.

1) Increase Internet connection to 10mbps  and configure site-to-site VPNS in a mesh configuration so that each site has a vpn to each other site. This would create six vpn tunnels.
 
2) Configure so that only Exchange and VoiP traffic use the MPLS network under normal conditions. All other traffic (backup/misc apps) should be routed to use the Internet VPNs. If the MPLS fails of course we would like the Exchange and VoiP traffic to fail over to the VPN connections as well until the MPLS comes back up.
