I have 3 877 ADSL routers for internet connectivity. I recently installed a FW behind them and would like to use the Ciscos as load balance in order to get better utilization from my 3 internet links.
1) the 3 routers are on DHCP from the ISP on the WAN side.
2) the 3 ciscos are on the same class C subnet on the LAN side: 10.201.1.252, 10.201.1.253 and 10.201.1.254
I'm setting up a lot of small remote sites that are only reachable via VHF ethernet radios that operate at 32k. I'm going to be using 2 of these radios shooting to two seperate base station radios to provide diversity. I'm going to have a Cisco 1941 sitting between the two radios and the way I have it configured now is to only use one radio and the second is only sitting there in case the primary fails. I was thinking though that I could load balance them to give a little more throughput. The devices at these sites are really low speed but we like to use snmp to monitor everything that is ethernet so I wanted to give as much bandwidth as I can.
Will load balancing work in this situation? What would the basic configuration be? This is all internal to our network so there are no ISPs to deal with. We're using C1900-UNIVERSALK9-M IOS will that work or will I need to change that?
I'm have ether channel between CISCO 6506 and CISCO 3750X. I'm set load-balance ip-src from 6506 side and dst-ip from 3750 side. i'm try test etherchannel for detect physical link for test ip. On 3750 all work, but on 6506 i'm get error: test etherchannel load-balance interface port-channel 1 ip 10.10.10.2 10.10.10.1 ^ % Invalid input detected at '^' marker.
View 1 Replies View RelatedEther channel: Cisco documents say Cisco uses proprietary hashing algorithm to compute a binary pattern that selects a link in the bundle. For example below a 2961 router with a switch module " NM-16ESW" performs" XOR" operation to compute the binary value to select a link.
R1#show ether channel load-balance Po1 ---> Source XOR Destination IP address.
1)Would you guys share the output " show ether channel load-balance" on your platforms?( i just want to see how different platform support different algorithm besides xor). Layer 3 ether channel on a sw.
On router, we first create ether channel and then assign int into port channel. Suppose we have a layer 3 switch and we want to put ports f1/1-2 in port channel 1. Can i configure like this: sw(con) int range f1/1-2 no switch port
channel-group 1 mode desirable. Or we must create a port channel just like we do on router and then assign ports to port channel?
Backbone fast: Suppose we have a switch with three ports, f1/1.f1/2.f1/3.
f1/1 ( root port)
f1/2( blocking)
f1/3 ( designated port).
Backbone fast is enabled on our network. Suppose sw receives a inferior bpdu on its current root port f1/1. Sw sends out RLQ on its designated port(f1/2) and Blocked port (f1/3). Suppose sw receives the rlq reply on its designated port ( f1/2). What will sw do? Will it expire the max-age timer on its root port ( f1/1) or will sw wait for all the rlq responses then expire the max-age timer on its root port ( f1/1) ?
I am installing a several new Cisco VM servers. The VM hosts are losing connectivity when we apply the etherchannel config in the core stack. VMware has stated that the etherchannel load balance needs to be src-dst-ip in order for the etherchannel to work.However, my current stack has 2 etherchannels configured to other switches through out the bldg in network closets. The current load balance configuration is src-mac.My question....when I make the change to src-dst-ip, will my network connectivity go down? I saw there was an older article on this that doesnt provide an answer just a work around. Here is the article. [URL].
View 1 Replies View RelatedI 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?
I want to split my traffic between two ISP's. I want all traffic to pass over one connection EXCEPT my VPN tunnels, which I want to use the second ISP. How should I set up (protocol binding?) to accomplish this? (I have run into various problems trying to load balance all traffic. So I am trying to "partition" traffic.)
View 1 Replies View RelatedI have set up an RV042 v1 and v3 both in Load Balancing mode. Set in Router mode.I want one of the WAN ports to be preferred so I added a static route to 0.0.0.0 metric 5 to that WAN.Sometimes the route shows in the routing table and sometimes it goes away!!
View 2 Replies View RelatedI have several RV16 with two internet connections each one, but different speed each wan connection, it takes the slowest wan connection allways, I use the round robin option, any clue in configuring?
View 1 Replies View RelatedI 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.
ISP environment with 3 Cisco 7200 BRAS ( NPE-G2 ) , we need to load balance traffic between two of them so the load balancer will accept traffic from backhauling link and distribute traffic the upper two BRAS , can we achieve this using spare 7200 we have or is there any software solution can do this .
another question , Cisco 7200 VXR ( NPE-G2 ) , does it support concurrent calls or sessions from more than 16000 subscriber ?
I've purchased a Linksys RV042 hoping I could connect my two ISP.Both of them are 1/1 Mb, first is DSL second PPPoE connection.The problem is that on system summary page it doesn't show me that second WAN is connected. Even when I trying to manually connect to Internet it doesn't work.
When this connection is in Load balance Mode, internet is very slow, sometimes it's even disconnected.
My question is:How to configure Load Balance properly?I've tried this page:
[URL]...
We have an RV042 on firmware version 1.3.13.02 and 2 ISPs:
WAN1 = Telepacific T1
1.5Mbps down and 1.5Mbps up
WAN2 = AT&T U-Verse
12Mbps down and 5Mbps up
I have it set to Load Balance, Primary WAN = WAN2
Network Service Detection enabled, only pinging the Remote Host of 4.2.2.2 and set to Generate Log
Bandwidth is set to:
WAN1 = 1000Kbps upstream & downstream
WAN2 = 5040Kbps upstream & 12000Kbps downstream
It seems to pick WAN1 a lot of the time. Do I have something setup wrong?
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?
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.
i am having a problem of load balance traffic over two WAN links connecting our 2 cisco 7600 routers, as i just knew that 7600 is not supporting per packet load sharing only per destination and as per our monitoring tools that one link is underutulized the other is overutilized.
View 10 Replies View RelatedI have the requirement to provide a Cisco Router with 3 x ADSL lines (768k) to increase the internet speed.PPP multilink is not supported from the ISP.
Is it possbile to distribute the traffic between this three ADSL lines?How can I configure this?
I have the following hardware configuration:
1 x CISCO1921-SEC/K9
2 x EHWIC-VA-DSL-B
The third ADSL line is connected over an ADSL modem at one fixed Router Gigabit interface.
I am trying to make this router prefer Wan1 for outbound while listening to both WAN ports for Inbound. I set it to Load Balance mode and added in a rule for Protocol binding:
All Traffic( TCP & UDP/1-65535)>192.168.1.1~192.168.1.254(0.0.0.0~0.0.0.0)WAN1 ENABLED
This says bind all Outbound traffic to anybody to WAN1
My Wan 2 connection is over satellite so it is easy to tell if a ping is going over Wan2 because the latency is >600mS
If I start a continuous ping to outside site - eg Yahoo.com then if I Fail WAN1 I see the ping latency Jump from 30mS to 700mS as it starts to use Wan2. If I restore the Connection to Wan 1 then the pings stay on WAN2 - seemingly forever. If I stop pinging for 30 mins then a restart of pinging does use Wan1 - so it fails back eventually If I restore Wan1 and then remove Wan2, it fails back right away
My problem is with our VOIP which uses a connection keepalive so there is no real downtime for the router to release the path to WAN2 should it fail over how I can force the router to fail back to Wan1 without removing Wan2?
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.

--- 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?
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.
