Unequal Cost Path Load Balancing With Static Routes?
Jul 20, 2011Can it be done? Load balancing across static routes with different administrative distance? Like EIGRP.
View 9 Replies View RelatedCisco WAN :: 6513 / EIGRP Unequal Load Balance Calculations?
May 15, 2012I 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 Firewall :: ASA 5540 Load-balancing Over EIGRP Not Working
Nov 15, 2011We have an ASA 5540 running 8.4(1) on the inside of dual Internet-facing border routers. The routers run BGP facing out and EIGRP facing in, with the ASA also running EIGRP for the same AS. Both routers redistribute a default route into EIGRP. It was my understanding and expectation that the ASA would learn both of these, as they are equal cost, and load-balance the outbound traffic over the two links. This does not appear to be the case.
The routers both have:
router eigrp 100
network nn.nn.nn.nn 0.0.0.0
redistribute static

Cisco WAN :: 3750 L3 / EIGRP Load Balancing While Running HSRP?
Dec 15, 2010I'm trying to configure load balancing on a network that is using 4 3750 L3 switches. The network is comprised of two sites with two switches at each site running HSRP and the virtaul IP is the gateway for a server between the two switches. The sites are connected by two independant 200meg ethernet connections (technically they are GigE limited to 200meg) p2p circuits. The switches at site A are connected together via a GigE port and the server I have connects to each switch at its respective site using a GigE port and the same for site B.
The problem I'm running into is that I've noticed that one of the 200meg circuits is always idol unless the primary goes down, so I'd like to be able to load balance the traffic from site A to site B using both p2p circuits. I think the problem that I'm running into has to do with the fact that HSRP is putting one of the links from the server to switch in standby unless the WAN link goes down and therefore traffic is not taking the "longer route" to the 2nd 200meg circuit.The only traffic going across this network is only the two servers sending traffic to one another. how I can get load balancing to work or if it is a possiblity with this network topology?
Cisco Routers :: RV042G - Protocol Binding And VPN With Load Balancing
Oct 6, 2012I have dual WAN connections on rv042G in "office 1". LAN is 192.168.10.x
A gateway to gateway VPN is made with another "office 2" on rv042G too.
The goal is to reach the LAN of the other "office 2" : 192.168.5.x
Working good. Now I need to use protocol binding : One LAN ip need to use WAN 2 : All traffic :192.168.10.77~77(0.0.0.0~0.0.0.0)WAN2 -> Working
The rest of LAN should use WAN 1 (same as the VPN) When I create this rules, I can't reach the "office 2" LAN : All traffic : 192.168.10.100~150(0.0.0.0~0.0.0.0)WAN1
What should I do to make it works ?
Cisco Routers :: RV082 V3 Load Balancing (Protocol Binding) With IPsec Tunnel?
Mar 14, 2013We have tried a variety of options in an attempt to use Load Balancing (Protocol Binding) with an RV082 that has a site to site IPsec tunnel with another RV082. Both are v3.
Here is the issue. We have dual ISPs, one has great bandwidth, but we incur overages. The other has mediocre bandwidth, but has unlimited usage.
GROUP1 - We want most PCs to use the "unlimited" ISP for general surfing, email, etc. (Bound all ports for range of internal IPs to ANY dest to WAN1)
GROUP2 - We want to use the "faster" ISP for our VPN tunnel (mostly RDP and SIP traffic). (Bound all ports for range of internal IPs to ANY dest to WAN2)
So far everything works. The router will route traffic appropriately and GROUP 1 uses WAN1 and GROUP 2 uses WAN2.
Unfortunately, sometimes GROUP1 users need access to resources over the VPN (WAN2).
There is something not right with the routing. For example GROUP1 can ping and receive responses from devices on the other side of the tunnel, but GROUP1 can't access intranet sites on the other side of the tunnel. They also can't RDP to PCs on the other side of the tunnel.
Why does the router correctly route ICMP, but not RDP?
We've tried adding additional protocol binding rules for specific ports(80, 3389, etc) and ip ranges (both local and remote) to see if we could force GROUP1 traffic destined via VPN through WAN2, but it doesn't work.
Shouldn't VPN tunnels created and configured in the RVs not adhere to protocol binding? It just seems logical to me, but maybe I am missing something.

Cisco WAN :: 1841 Unequal Load Balance With Static Routes
Oct 3, 2011I 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 :: 2811 DSL Load Balancing
Dec 9, 2010I 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.

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?

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
Feb 3, 2013I 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).

Feb 24, 2011We 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.

Cisco WAN :: ASR 1000 Multiple ISP Load Balancing?
Nov 21, 2012I 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?

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.
