Cisco WAN :: 1921 Dual ADSL Load Balancing / Failover?

Mar 28, 2011

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?

Cisco Routers :: RV042 Both Failover And Load Balancing?

Jan 27, 2012

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.

Cisco VPN :: ASA 5520 - Load Balancing With Active / Standby Failover

Jul 8, 2010

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?

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 ?

Cisco WAN :: 1841 Router With Dual WAN Load Balancing

Oct 9, 2012

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?

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 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 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?

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 (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.

Cisco WAN :: ASR1001 - Internet Load Balancing

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.
