Cisco WAN :: 3560 - Switch Not Communicating With Load Balancing Router
Nov 18, 2011
I have a Cisco network on a ship where I work, I have an Ericsson GSM Access point which picks up local GSM 3G signal and broadcasts it onboard. I have two of these units and they are connected to a D-Link Load balancing router which is in turn connected to a Cisco 3560 Series 8 poe switch. Each unit is on a different subnet. The Cisco is on the DHCP server from my AD server (Windows 2003 Server) The Load balancing router has no DHCP and the Ericsson units have their own DHCP servers.On the Cisco switch if I plug in with a laptop I get an IP address for the DHCP on my server. I cannot ping the load balancing router from it. If I connect to the Load balancing router and set a static address for that subnet I can access the internet via the Ericsson units. And if I connect to the Ericsson I can access the Internet.
We have two 100 MBPS P2P link from two different ISP and we have terminated both the link on our 6509 switch. Now we want to configure the load balancing between these two disfferent ISP 100 MBPS P2P link.
So, how to go and what all options we can try ? We are thinking for Ether Channel configuration. Need your expert opinions on the same and if etherchannel configuration is the option then what would be the configuration for the same ?
I have a 1841 router having 2 ISP links , till now I have been using IP SLA for NAT Failover but now I want to use OER to do Load Balancing and utlize both of my internet links . 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 ?
I'm setting up a warehouse near Dayton, OH which will require a high level of network availability as there will be no local IT staff. To that end I've decided that a router that supports load balancing of 2 WAN connections, HA, and a T1 interface would be ideal. To clarify the load balancing requirement, the location will have redundant internet access plus a point to point T1 to the main office to facilitate low latency connectivity between a warehouse management system and ERP back-end. Total user count at the warehouse is 5 and 20 at the main office. Neither location has tremendous bandwidth requirements.
I have little practical experience in this area, but I have come up with 2 solutions thus far.
The Juniper solution is likely a safer route given access to vendor support, however, this option becomes rather spendy as I'd like to use the same configuration at the main office which will require 4 units. The Vyatta option, although probably less proven and a bit more risky, could run on a pair of Sun x4100 systems at each location which I can purchase for around $200 each plus the cost of the Sangoma cards.
We've got a 1841 router with dual-WAN connection, one is Cable and it goes to Fa0/0, another one is ADSL2+ and it goes to WIC-ADSL card.I'm trying to configure a load-balancing and failover using per-packet or per-destination connection.I can configure "ip sla" for both connections pinging 2 different DNS IPs of 2 ISPs. But I can't configure command "track 1 rtr 1 reachability" and "track 2 rtr 2 reachability". There is no "rtr" allowed to type there. And all examples shows that command for load-balancing. What command to use for that or why I cannot use the above command?
Can we terminate 2 WAN link first Lease line and second Broadband internet link on 800 series router . As 800 series router have only 1 wan port and 4 switch port. Also we want to Configure load balancing over the 2 WAN link, is it possible or Basic router for SMB.
I have some problem connecting to sites when I'm using the router in Load Balancing mode on the 2 WAN. Looks that when a connection to a site is started with a WAN is not manteined with this one but jump from a wan to the other, causing, in some site like Home Banking to be disconnected every time. I would like to know if it's possible to configure the roouter in Load Balancing but Bindind the source and the destination IP address so the same wan will be used for the entire time this connection is up. In opther words the Load Balancing has a sense beetween connections not beetween the same connection.
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.
One of our customer just purchased ASR1002 router, they have three internet links from different ISPs and they dont have any remote site, they have three different public IP pool as their respective ISPs. So, is it possible to load balance the internet traffic using all three link on Cisco ASR router ( IOS - Advance Enterprise Services)
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?
Currently we have deployed site to site vpn between 2 asa 5510 model. one is corporate site and one is remote site. now we plan to use radware load balancer in which 2 isp will terminate. now if at a remote site wecreate only 1 ipsec tunnel and mention sigle isp peering. if one isp fails at corporate how remote site will be access by site to site vpn through 2 isp vpn. what thing we need to do over asa as well as load balancer at both end.
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.
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 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.
I have two Internet connections which are connected to two ISR 2951s. Also I have two ASAs 5545-Xs, which I want to use in Active/Active failover mode with multicontext. The question is: how can I configure ASAs to perform ISP load-balancing as well?
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?
SIP Load balancing Issue with ACE 4710?I have a Cisco ace 4710 with vesion Version A4(2.2). i configued simple SIP load balancing first without stickiness. without stikeiness we are having a problem because bye packet at the was not going to the same server all the time that left our port in used even though user hang up the phone. its happen randmly. i have a total 20 licenced ports and its fill out very quickly. so i dicided to use the stickiness with call-ID but still same issue. below is the config
rserver host CIN-VOX-31 ip address 172.20.130.31 inservice rserver host CIN-VOX-32 ip address 172.20.130.32 inservice
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.
We have two asa5520 configured as primary and standby unit in fail over configuration, and all is working properly. Is it possible, with this configuration (fail over), to configure vpn load balancing/clustering?
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.
