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.

We are now using a ASA 5510 firewall and we would like to configure a internet load balance traffic in our environment.For example, some IP addresses go through local gateway for internet routing but some address go through VPN tunnel gateway.
View 1 Replies View RelatedWe 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.
WE got our ESXi servers recently moved from a 6513 to nexus 2000 FEXs uplinked to a nexus 5000s basically we have enhanced vPC and nics goin to 2 different FEXs and they uplink to 2 nexus 5000.
the Vswitch for VMs is setup in a VPC. Question is do the traffic from each vm going in/out of these nics in a vpc actually use both physical links? How can i tell from the switch?

View 6 Replies View RelatedI'm configuring Control Plane Police in a Catalyst 6509. This equipment is using IS-IS like its IGP routing protocol, and iBGP. In order to make CoPP work Im classifying the traffic entering the control plane like CRITICAL, IMPORTANT, NORMAL, UNDESIRABLE and DEFAULT. Obviously routing protocol traffic must be classified like CRITICAL. Doing so is easy to BGP because it runs over TCP/IP and I can configure the following access list to classify BGP:
ip access-list extended CP-CRITICAL-IN
remark #### CONTROL PLANE CRITICAL TRAFFIC INBOUND ####
remark #### ROUTING TRAFFIC - BGP ####
permit tcp host [BGP neighbor addr] eq bgp host [local BGP addr]
permit tcp host [BGP neighbor addr] host [local BGP addr] eq bgp
deny ip any any
But IS-IS is also a CRITICAL traffic, but IS-IS doesn't run over TCP/IP, rather it exchange its own PDUs. So, how do I classify IS-IS traffic with an access list?

View 4 Replies View RelatedI have problem with traffic coming from GRE interface and going further through FWSM on the same 6509-E chassis.It's very interesting and confusing. If packets are fragmented, I can go through, however, if I use normal packets (usual ping for example) traffic goes from outside to inside and stops on it's way back.
Here is the detailed info:

FWSM HW 4.0, SW 4.1(4)
GRE is done in hardware (source is loopback interface - only one loopback per GRE tunnel).
We are a new medical school located in PA. Just have just completed a new building and are now working on getting our network finished. Here is the situation we have a 50MB Internet Connection that comes into our network that then hits the ISPs Cisco 3750 which sends it to two of our Cisco 3750s for redundancy. From the 3750 goes into our Cisco 6509 with a FWSM module, then out from there to our distribution switches which are all Cisco 2960s.
What we would like to do is to control how much WAN connectivity each of our VRFs get. Right now we have a Faculty, Student, and Research VRF formed, and are trying to figure out the best spot where we can say Faculty gets 30MB of Bandwidth, Students gets 10, and Research gets 10. If possible would like burst capabilities.

Now My core switch can learn mac address across its trunk port where CAS servers are connected on dedicated switch. but still i can see traffic Transmitting out to my all switch ports of same VLAN ( same as NLB VLAN).
I trying configure ASN traffic load balance, but doesn't works.I have one Cisco Catalyst 6509 and onde Cisco Ace10 module, in my context "PanWEB" i have the interfaces above: [code] If i try to establish a telnet session(telnet 10.96.202.10 80) i see the SYN packet passing through the ACE and going to the real server, but, the server do not response the SYN packet. I done a capture in the server using wireshark and could see that the IP address of the destination is the VIP and not the rserver ip address , this is a problem? Why can not I have the SYN + ACK from the server?
View 5 Replies View RelatedOn a Catalyst 6509 switch I have configured wccp protocol in order to redirect the Http traffic to a Bluecoat SG8100. It was working fine until a new L3 interface implementation.Thereafter I was unable to redirect the http traffic due to an error reported from the Cat6509: [code] After some checks I supposed that the problem should be the UDP 2048 port connection between the Switch and the Bluecoat while the switch L3 port and the bluecoat are on the same Lan. A deep analysis found that the WCCP protocol seems to be as follow:
-Proxy address 10.64.28.240 to Switch Port 10.64.28.250 Here I Am
-Switch Port 10.64.28.250 to Proxy address 10.64.28.240 I See You
-Switch Port 10.66.0.251 to Proxy address 10.64.28.240 UDP 2048 packet (dropped by firewall)
It's strange to me that the first dialog is correctly handled by the correct Cat6509 interface while the UDP packets are flowing from another Vlan interface not configured with the WCCP and apparently not involved on the protocol.Last of all the WCCP is now disabled and unusable?

I am aware that the 3750 switches are not able to support Netflows, so I have created a SPAN port and spanning traffic from a specific port. I would like to create a seperate VLAN and trunk the traffic from the SPAN port down to the 6509 switch and then capture all the traffic for that VLAN on the 6509.
View 4 Replies View RelatedWe have a pair of 6509 working in a VSS configuration (IOS 12.2(33)SX5). The 6509s connect to a pair of ASAs (7.2 code) running in an Active/Standby setup. These ASAs in turn connect to routers going to remote sites. I have configured Netflow on the following VLANS,
VLAN 10 - Servers Vlan
VLAN 9 - Transit/ASA VLAN (connects ASAs to 6509s). All traffic originating from any VLAN on the 6509 crosses this VLAN in order to reach remote sites and vice versa
I configured the netflow source VLAN 11 although I am not collecing any netflow from it.Although I have been getting lots of Netflow info, I noticed that netflow for traffic originating from any user VLAN on the 6509s going to any remote site via TRANSIT/ASA VLAN(9) does not get reported, I even tested with 4 GB traffic but no result. Only reverse traffic (i.e. from remote site to user VLAN) is reported as it traverses the Transit VLAN (9).
I read somewhere that egress netflow is not supported in 6500, but isnt traffic originating from a user vlan to a remote site via the transit VLAN (9) considered ingress with respect to the transit VLAN (9)? I would like to know whether bidirectional Netflow is supported on 6500 VLANS. I have mimimum control on routers beyond the ASAs, and since these ASAs run 7.2 code netflow is not supported, and Monitoring this Transit Vlan gives me extremely useful info.
I do get netflow biderectional traffic from the Server Vlan 10, but I think it is correlated by the netflow collector from vlans 9 and 10. [code]
I am attempting to block all FTP traffic on port 21 from the servers in my network, and only allow FTP from one server to go out.

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.

View 3 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?
