Cisco Application :: ACE 6509 In Routed Mode Design For Deployment

Sep 4, 2011

Current topology in network is such: web servers with content needing to be load balanced are in vlan 35 and these servers are directly connected to Core switch (two 6509 VSS) via 20 Gb EtherChannel. Vlan 35 also spans some other switches with other servers residing in this vlan. Additionally, there are dozens of another vlans (including external users) that need to communicate with web servers. IP addresses of these two web servers are: 192.168.35.1/24 and 192.168.35.2/24 accordingly with default gateway 192.168.35.254/24 (SVI on Core switch). Currently these ip addresses are used by management and other purposes and need to be reachable for same purposes after configuring load balancing with ACEs - it is needed to have direct access to servers behind ACE. How I can do that using ACE in routed mode?

Cisco Application :: Does ACE-30 Support Multicast In Routed Mode

Aug 30, 2012

We currently have ACE20's, which only support multicast in bridge mode.Was wondering if it's the same on ACE30's, or if Cisco finally implemented support for mcast in routed mode.

Cisco Application :: ACE30 Normal Load Balancing In Routed Mode

Sep 23, 2012

We are in the situation we have a active configuration with ACE30 doing normal load balancing in routed mode, we have tons of rservers going out on a VIP.we now had to add a new private network to a provider that strangely enough does not want to see our public or private addresses. we need to loadbalance towards him on a priovided subnet (still rfc1918) (IOS VRF bug? is that correct?)I have two options, add the network (new interface) to the active loadbalancers (contexts) and then tie in new policies to the active serverfarms or make a new context just to load balance towards this provider.(preferred)Now - If I do this, the rservers see the client source addresses from this new provider. as the loadbalancer does not "hide" the client IP's. I would then have to add static routers toward the new context - I would want to skip that.
 
is there a way, to make the loadbalancer hide the client addresses towards the rservers ? perhaps I'm just needing the correct search term to find the config example.

Cisco Application :: 6509 - ACE Module In Bridge Mode?

May 16, 2011

We have a 6509 with an ACE module. For reasons I don't fully understand the ACE is running using a BVI in bridge mode. It has loads of secondary interfaces.

[Code]...

I can ping all of the IPs on the BVI, but only servers in Subnet 10.7.42/42 can ping out of the the layer 3 on the 6509. I have all the routes configured properly on the 6509 pointing to the ACE for these subnets. The question is though the config has been excepted, is there a limit to the number of secondary on a BVI.

Cisco Switching/Routing :: 3750 To Connect Routed Interfaces And Vrf Design

Sep 26, 2012

I would like to do the following architecture with the same C3750 : network X,Y,Z connected to 3750 in VRF D the 3750 uses a routed interface on subnet E for the default route in VRF D on this routed interface a BYPASS EQUIPMENT the other BYPASS EQUIPMENT interface is connected also to another routed interface on subnet E "also" this routed interface is in another VRF C with other network A and B.do you know if it will work because of 2 routed interfaces on the same IP subnet or is there a way to do that ? the only goal for me is to catch traffic from network X,Y,Z on SYN and ACK.

Cisco Switching :: 3750 - IP / VLAN Planning For Routed Access Design?

Sep 10, 2012

We are currently designing a complete Layer 3 to the edge solution for our customers. The network design is a combination of a collapsed core (Core to access) as well as a three layer model (Core/Distro/Access) for connectivity to the Data Centre, Internet and Wireless Blocks.
 
The core of the network contains two 6509E switches interconnected on a Layer 3 Port channel (no VSS). Access Layer switches (3750 Stacks) connect to the core switches over p2p routed links (Collapsed core part of the design). Distribution layer switches provide connectivity to the Data centre, Internet and Wireless Blocks.(three layer model.
 
All IP addressing is being planned for assignment from the private RFC 1918 address block(10.0.0.0/8) for both Infrastructure and Access layer VLANs for users.
 
Clarifications required for the following:

Cisco Application :: ACE4710 Deployment Models Required

May 31, 2011

ACE 4710 deployment model.  We'll be doing an eval later in the year, but I'm just looking to understand the architecture.We have a stack of 3750 switches with a single VLAN (10.1.1.0/24).  Connected to that stack is a pair of web servers (10.1.1.5 and 6) that we want to provide load balancing/failover for.  Some of the clients are located right there on that same VLAN.  Other clients may be coming from other spots in the infrastructure.It sounds like I could put a pair of 4710s connected to that stack of switches, in a single arm deployment?  And then the virtual IP and the real servers would all be 10.1.1.0/24.  Maybe use an etherchanel to connect each 4710 to two 3750s?

Cisco Switching/Routing :: LAN Segmentation Design 6509

Apr 25, 2012

I've been tasked to come up with a design to segment our internal network to reduce broadcast domain size.  In addition, we are running out of DHCP available DHCP addresses.  I need to have a solution that will give me more available IP's, but reduce our broadcast domain.
 
We are Cisco VoIP shop.  Our current environment consists of dual 6509 chassis in a VSS config.  We have 10 access switches that are model 3750's.  Each 3750 has dual 1Gb fiber links to the VSS Core in an etherchannel configuration.  We have 2 VLANS (data and voice) that spread throughout every switch.  Both VLAN's have their own DHCP scope.
 
Our current broadcast domain is a 255.255.248.0, so we have over 2000 potential broadcast devices.  Cisco recommends not having larger than 512.  So my research has brought me to a design as follows:
 
          MY DESIGN:
>  Have individual voice and data VLANs for each closet switch. 
>  We have 10 closet switches so this would require 20 new vlans
>  With every separate VLAN we would need a different DHCP scope. 
>  Configure 20 new DHCP scopes for the 20 new VLANs. 
>  Each DHCP scope would have a 512 available addresses.
>  Enable IP Routing and configure EIGRP on the VSS Core and 3750's.
>  I'm tossing around the idea of have each 3750 be an EIGRP Stub.  Not sure yet.
 
          QUESTIONS:
1.  How to verify what I described in my design? 
2.  Any alternative solution that might be less complicated than configuring Layer 3 on all my access switches? 
3.  Any thoughts on configuring EIGRP Stub vs. having the VSS Core do all the work?
4:  Any template that I could base my 3750 config from?

Cisco WAN :: 6509 Fwsm Multiple Subnets Routed On One Port From 3750

Dec 20, 2010

We have a 6509 that was connected to 2 other locations(location A and B) and our local lan (location MAIN).  We wanted to move the location A and B to a 3750 switch and only allow the traffic that needed to access our location MAIN to come through the firewall.  The only problem I ran into is that before location A and B were on different interfaces so in the 6509 firewall the routes for traffic to our MAIN location was done by static routes.
 
I.E.
static (MAIN_intf,A_intf) 192.1.1.72 10.94.10.72 netmask 255.255.255.255 0 0
static (MAIN_intf,B_intf) 192.2.2.72 10.94.10.72 netmask 255.255.255.255 0 0

[Code]....

because it has a static overlap, which makes sense to me, but my question is how do I configure the network to get this to work?  Do I have to reconfigure my network and access-list?  Do I need to add more ports between the 6509 and 3750?  I'm not sure if this is the best way to do what we want. If something is not clear I'll try my best to explain the setup, but I just took over for our I.T. guy when he left.
 
I put 10.10.10.72 instead I should have put 10.94.10.72. the routed port is on a different subnet than the computer I'm trying to access.

Cisco Firewall :: 5512 - BGP Through ASA Versus Transparent Mode Deployment

Mar 8, 2013

I've been asked to deploy an ASA in Transparent Mode because of concerns of putting another layer 3 hop between PE and CE routers running BGP.
 
Is there some problem with allowing BGP to flow freely through an ASA the is also terminating site to site and remote access vpn tunnels?
 
I just don't see the need for Transparent Mode here and you cannot have a standard DMZ setup with Transparent Mode: you have to use bridge groups to provide for multiple interfaces on the ASA and then have an external router route between those bridge groups.
 
what I'm missing here as to why Transparent Mode is needed (not needed)

ASA is 5512

Cisco Switching/Routing :: 2960S / 6509 VSS - QoS Design Options?

Sep 26, 2012

On occasion employees are downloading large files for business purposes, at very fast speeds. This has the potential to overwhelming our Internet circuits which causes our Customers problems accessing our Web Hosting services.
 
Our network is comprised mostly of 2960S switches for the employees. Webservers are connected to other 2960(nonS) switches and directly into the 6509 VSS.
 
Customer’s traffic comes in through one pair of ASA’s.
Employee’s traffic is handled by another pair of ASA’s.
 
Employee traffic flows from the 2960’s, past an L3 SVI on the 6509, then through the Employee ASA’s, then to the ASR’s, then out to the ISP#1 or ISP#2
 
Web Server traffic flows from the 2960’s or 6509, to the Customer ASA, then to the ASR’s then out to ISP#1 or ISP#2. Web server traffic does not flow through an L3 SVI.
 
The goal is to allow employees the ability to have the most bandwidth they can, however customer traffic always has to be preferred in the event of a ISP circuit approaching its limit.

Cisco Application :: ACE 4710 Deployment - Load Balance HTTPS Requests From Internet

Oct 17, 2012

I’m looking for some notes from the field guidance here from those that have much more deployment experience.
 
I have a GSS and an ACE, and its the ACE that's primarily giving me something to think about, in terms of placement and what mode to adopt.
 
The traffic flow will look loosely like this:-
 
Client---Internet---Firewall---GSS---ACE---Servers
 
Physically, it's like this. The RED line denotes a boundary, and pretty much anything North of that is not accessible to us, we simply have a L3 trunk between our switches and "their" switches (S3/S4) and talk using EIGRP.
 
There are other servers in the top tier, some that also require load balancing, some that don’t. Typically, I want to load balance HTTPS requests from the internet, to one of the 3 servers in the top half.
 
I’m not sure what mode to select, routed, one arm? What about placement of the ACE? At the moment, I’ve just configured 1/1 on it and made it part of the MG MT VLAN, it's S VI exists on the S1/S2 switches, so I’m open to change as it's still all in the lab.

Cisco Firewall :: ASA 5500 - Transparent And Routed Mode

Jun 26, 2012

have a Cisco ASA that I am trying to configure in a unique way, I want it to perform a variety of tasks;
 
VPN SSL
VPN Tunnels
Firewall Inside to Outside via versa
 
But the difficult task, is creating a DMZ with devices that are assigned fully routed IP addresses from our ISP directly, these are H323 and SIP devices that cannot use NAT, and must have a fully routed IP address assigned to them.
 
Obviously the problem I have with the Firewall in its default routed mode, is that it wont allow me to overlap IP addresses on the outside interface with the DMZ interface.
 
Could the Firewall be configured for Transparent mode between Outside and DMZ, but Routed mode between Outside and Inside?
 
Eth0/0: 10.0.0./24 (inside)
Eth0/1: 190.0.0.0/24 (dmz)
Eth0/2: 190.0.0.0/24 (outside)
 
[Code]....

But could the new Cisco ASA with the latest firmware and model be ale to do this with 1 physical firewall?

Cisco Application Networking :: ACE 4700 One-arm Design With SSL Termination?

Sep 17, 2008

We are evaluating the one-arm design for the ACE 4700 and need some clarifications:
 
1. Are there any limitations in the one-arm design and the SSL offloading
 
2. Can the ACE be configured with an IN and an OUT vlan to the router
 
CLIENT -> Router -> ACE IN -> ACE OUT -> Router -> Server Vlan
 
so that the SSL and the clear text traffic is in a separate Vlan?
 
3. In some sample configuration i saw SNAT configuration on the ACE to modify the client IP. This i assume is for instructing the return traffic from the server to go through ACE? Using SNAT we eliminate the requirement for NAT or PBR on the router? Will i still be able to insert the client IP address after the SSL offload?

Cisco Application :: ACE And FWSM Design And Configuration Guideline With 6500

Apr 8, 2013

I have Cisco 6500 with FWSM and ACE module which are in one central DC. Also we have four different Datacenter (Hub & spoke) and in our FWSM we have configured four contexts in central DC FWSM for each DC. Each DC servers are different VLAN and IP subnet. Now we have to configure ACE module for load balancing among those different subnet servers. What will be the design and configuration for this solution? Like routed or one-arm mode design.
 
Scenario Example:
1.  App Server01
IP:192.168.11.5/24
GW: 192.168.11.1 in FWSM
FWSM Context: DC1
Physical Location:DC1
VLAN:11

[code].....
 
Now customer requirement is we have to load balance using ACE between these App Servers which are in different context s in FWSM and one Server is not FWSM. how to configure or design or placement of ACE and FWSM for above scenario.

Cisco Firewall :: 6509 - Is It Better To Setup Firewall As Transparent Or Routed

May 9, 2011

I am familiar with the PIX and ASA's.  We have two Cisco 6509's with a FWSM installed in both.  Our network is shown in the diagram.  We use Blue Coat Packetshapers and Barracuda Proxy appliances.  I plan on setting up HSRP on both 6509's for traffic coming from our ISP Cisco 2811's as well as use HSRP for our DMZ and internal network.  I would like to setup the firewalls for statefull failover.  We will be using PAT for our internal users and one-to-one static NAT for our DMZ. 

Is it better to setup the firewall's as transparent or routed?
 
Since the firewall is built into the switch, how do I insert the Barracuda proxies?  I can configure them as transparent or routed proxies.

My problem is: The clients are complaining of slowness connection to the internet, i captured the traffic in the ace capture feature and i see some RST packets and severals checksum error packets in pcap file.
 
The topology is:
 
Client -> ACE VIP VLAN 81 -> RSERVERS VLAN 80
 
Vlan 80 is in L2 mode(no interface vlan in the switch core 6509, route occurs through the ace appliance).
The IP address 10.96.200.6 is the gw for rservers.
