Configure HSRP With Statefull NAT Using The Application Redundancy Of The IOS XE?
Mar 6, 2011
How to configure HSRP with Statefull NAT using the application redundancy of the IOS XE? I want to have static NAT using the HSRP groups for clients and SNAT. (I want to achieve this as in normal IOS -[URL] High Availability NAT with HSRP)The configuration that I have on the 1st ASR. The configuration is similar on the second ASR
redundancy
mode none
application redundancy
group 1
name NAT-HSRPIN
[code]...
IP nat inside source static 10.10.10.20 "real ip address" redundancy 1 mapping-id 1 extendable.
i have a 6509 connected via layer 2 (VLAN1) to a 3750 (e.g. VLAN1 10.1.1.1)then to the HQ via Metroethernet(L3). Is it possible to connect the 6509 to an ASA that already has VPN connectivity to the HQ using HSRP? Also need to mention, the VPN connection is supposed to be the redundant connection if Metroethernet link fails.
I am facing a problem in implementing HSRP. My scenario is like this, I have two 3750 switches and I have a server with two NICs. I want to run HSRP in these two switches. By the way the server is connected directly with the switches. I mean each NIC to each switch.we have teamed the two NIC (Active / Standby).what configuration need to done in switches to work HSRP.
1 x 4500 and 1 x 3560?They are gateways of 8 Vlans?They are doing HSRP in each of those Vlans?The 4500 is the Active?There is a DHCP Pool for each of those Vlans on both gateways using "ip dhcp excluded-address" I ensured that the range of provided ips by each DHCP server will not be overlapped Obs.: Reducing the lease time, I ended with the calls bringing related problems.
OK, every thing is blue, every thing is fine.But the network diagram is realy complex(41 switchs, 89 uplinks), and depending of how is the network flow, one or other server answer first or latter.
For many reasons I would like that the secondary DHCP server would answer only if the primary DHCP server goes down.To me, the bigger reason is that DHCP database would be only in one DHCP server.But there is other reasons.
I passed by many frustrated solutions:Try to force a delay on the answer on one of the servers. - Impossible.Try to disable DHCP server, and, using EEM, enable it only if router became active in HSRP. - I couldn't do It.
What I'm thinking now is use the HSRP resource to resolve it.On both routers I would put a "ip helper-address" pointing to an Virtual_HSRP_IP.And depending on which router is the active, him will answer the request.
My first doubt is:Would it work?The second doubt is:Could I use the same Virtual_HSRP_IP that exists on that Vlan(see example 1),or I would need to point it to a Virtual_HSRP_IP in a different Vlan(see example 2)?
Example 1 ----------------------------------- | 4500 | ----------------------------------- interface Vlan1 ip address 10.10.0.2 255.255.0.0 ip helper-address 10.10.0.1 standby 1 ip 10.10.0.1
One of our customer , where there 2 6509 switch , one is Core_sw1 and other is Core_sw2 , catering about 32 Vlan , and HSRP in running for all Vlans , till here no problem , now there internet Router which having one Internet link , which connected and configured on Core_sw1 in a way that one interface of Core_sw1 is given Public IP and there is vlan 85 which internet vlan and vlan 85 ip are natted with that public IP with one simple static route given toward internet router , this is how internet is working ok.
Now i have configured vlan 85 in hsrp as all other are , how can give redundancy to vlan 85 user , that if Core_sw1 get down , internet traffic can get out through Core_sw2.using same internet router with single internet link .i am not talking of ISP redundancy , but Vlan 85 in Core_sw1 goes down , other Core_sw2 will server internet.
If I setup 4948E's in HSRP configuration. And I connect devices to the Standby Unit that do not require redundancy. Will there be any issues passing traffic? I don't believe that standby unit blocks the traffic but wanted to confirm.
what is that mean-"Redundancy is not supported between an ACE module and an ACE appliance operating as peers" I'm designing network in which I plan to use ACE-4710-0.5F-K9 appliances.
recently when i run the commit vip redundancy script, i encountered the following error. This script has never failed in the past. Upon checking the backup CSS, i did notice that my most recent changes were actually synced. The following is the debug i have captured while running the script.

Since the ACE supports only static routing, when pointing a default route from the ACE what is your preferred method when using multiple 6500s with an ACE in each in a failover scenario to prevent just pointing at one 6500? Static route to an HSRP address? Multiple static routes on the ACE, etc?
Can the above be used to provide redundancy. However there is only one ISP side connected? Of course we can set up both with exact same rules and use a Manual power on/off if?
The Issue we have two 3750 switches and configured hsrp on that . Now instead of connecting these two swiches to an Intermediate common switch we have a cisco asa5520 which has 3 L3 ports of which is it possble to convert 2 ports as L2 ports and use those ports to connect to 3750 switches instead of a L2 switch.
I just started a evaluation license for IP Base on my 3850 switches. But i can't configure HSRP cause the commands are not there (I rebooted allready). Do you need enterprise for HSRP on the 3850?

I was trying to assing statefull link as same as LAN failover link on ASA5520 with VPN Plus license. But i am getting the below error. Is there any restriction in the license itself.
As per the attached diagram: How do I configure the 2 ports on the 3560 (Ports 6 & 7) and the connected ports on each of the 2960 switches (Port 25) to provide redundancy.
If the up link from Switch A dies then I need the traffic to flow through the trunk and utilize the up link on Switch B with minimal delay (milliseconds).
What consequences could i have if i install a WiSM-2 module into a pair of 6500 configured in VSS and another WiSM-2 module into other pair of 6500 configured in VSS for serving a 300 APs??...in this case, do i need to configure mobility groups for guarantee a high availability and also redundancy of controllers?Under the best practices, is much better having the two WiSM-2 modules into a single pair of 6500 configured in VSS??
Do you know if it is possible in ACE 4710 appliance to configure a SIP TLS ?The SIP probe we have in the configuration guide it is only for clear text. for Lync 2013 we need to establish first a TLS session and then within it, send an SIP request..IS it possible in any version? I tried also to configure a HTTPS probe but it fails as it sends a GET which the Lync SIP server doesn't understand.
I have CSS in single arm deployment model. I want to configure port redirection for the servers. Servers are actually running web service on port TCP 3636. Which is accessibale by VIP http://192.168.200.87:3636 but I dont want to give user this URL I want the user to use standard HTTP URL as mention below, I want user to open http://192.168.200.87 and once they access this URL automatically CSS redirect them to port 3636. How I can achive this. I am using IP addresses for the load balancing.
I want to compress as much all packets COMING IN to our network to optimize the bandwidth. When users from Lan accessing the internet, it goes out to our GW1 but I want the RETURN internet packets will go first to Expand 2 for compression then goes to Expand1 for decompression. see attached network diagram setup. All Expand appliances are already configured. What configuration should be in GW1 and R2, both C2851?
I have upgraded gss to version 3.2(0) because I need to track a server that uses only https.I configured a https head KA VIP answer type but the answer never goes on-line.I tried using url... as the VIP address but not go online too.The gss is behind a firewall.I suspected of the firewall but from the gss CLI it seems that the firewall is open for the https traffic: [code]
i have configure new ACE 30 module on top of 6500 core switch , the issues am facing whenver i want to access to https://ACE_IP and after i enter the user name and the password , it's forwared me to the follwoing page: is there anything should i configure to avoid this page ?
I'm looking for some documentation I can share with a customer to explain why I can't configure them a back-up sticky server farm when we're not terminating SSL on the the ACE (we pass SSL from the client through to the rservers, sticking the client to the rserver by source IP address). I've not been able to find anything that addresses this particular scenario in my googling so far. I remember discussing this in my training class with the instructor, but I can't find any reference to it. Have any of you run into this and have a link they can share?
My ACE module rebooted itself and after the reboot it lost all the config and it has been booted with factory default setting.
[code]....
I would like to know the reason for the same. Is this due to firmware bug? or with the Hardware? I am bit dissatisfied that all of my config vanished without any reason after the reboot of ACE.
I'm trying to configure Fault Tolerance on a pair of 4710s. I followed the doc, and configured int gi1/4 as the fault tolerance interface, using vlan 12. However the GUI is saying FT Vlan Down
The troubleshooting wiki said check the physical connectivity, but everything there looks good. Each ACE can ping it's own IP, but not the router on that VLAN, or the peer. They're connected to a dedicated VLAN in a switch, and I even tried a crossover cable to directly connect the two. [code]
We want to mask part of the path prefix to hide development content: For example: the site(s) are: [URL]However we don't want anything with acme showing...so we would want the loadbalanced url to be: [URL] ...for requests and responses. I think this would be an http re-write request/response scenario?Is this possible to configure this on the ACE Device? We've got the load balance configuration down...not sure how to do this re-write type scenario?
I'm looking for a way to configure Cisco ACE4710 loadbalancer to bypass traffic that is initiated from server side to Internet?Are there any way to configure this, so that the loadbalancer will not maintain session for this bypass traffic to maximize throughput?
Everytime I make a config change to one of the contexts on our ACE20, I get this message: Config Application in Progress. This command is queued to the system
