Cisco WAN :: Failover Routers Config 857
Feb 20, 2011
I’m currently training to take my CCNA, So for the reason I’m here, I have just been asked to take over the company network.And I need to know how I go about configuring some base level routers.I have 3 remote sites and 1 main site, all these routers are using 857’s, with a VPN tunnel between them, this is running all OK and working fine,But my boss has decided to have a second ADSL line installed in the main site for failover.How do I go about configuring this, ie how do the VPN’s terminate on the other router when the main one goes down?

We have two offices in the US and one in Mexico. Our site in Mexico connects to our headquarters in the US over an AVPN/ MPLS circuit .Mexico has a separate Internet connection through TelMex. There is an ASA 5510 at headquarters and an ASA 5505 in Mexico. We have a fail over VPN set up in the ASAs for times when the MPLS circuit goes down. All Internet traffic in Mexico is supposed to be routed to the TelMex connection. All company traffic is supposed to be routed to the Cisco router. ASA is supposed to be last resort route. We have a fail over VPN set up in the ASAs for times when the MPLS circuit goes down. (Or at least we did until I had someone work on the configuration) Everything had been working fine for the last 4 years.
Yesterday when the MPLS went down, so did their Internet connection. I realized the Internet traffic is now coming through the MPLs circuit to head quarters and out our ASA. Obviously there is a problem with the configuration. I do not have enough experience to figure this out. I have attached the configs and the routes for both the ASA and the router.

I'm attempting to configure two ASA 5520 for active/standby failover.When I enter the “failover” command to enable the config on the primary ASA, the entire routing table disappears.There is no routing process running, only static routes are configured.
Is this an expected behavior of the failover process and if so, how long should I wait for the routes to come back?

I am trying to simply erase infomation from certain configuration fields in an RV042G router. However, once an IP address has been entered, atempting to simply save a blank field results in the message "Please input IP address" and the empty field will not be saved.For example, we had a WINS server, but now we don't. I want to remove it from DHCP, but simply deleting the IP generates the above message.Likewise, atempting to remove an IP from the DMZ Host address returns an error. How can I reset these fields to be blank?

I am trying to create a bash script to log into routers and make config changes.I ran into a snag in that I am unable to pass a password for the ssh login.I tried tying an expect script to handle that piece but was unsuccessful.I saw on google something about public/private ssh keys (not the same type used to ssh into the box) but I do not want to go this route.Can this be done in another language other than a bash script?I would like to avoid TCL or EEM if possible, I want to learn a language that I can use for multiple purposes.

I'm replacing an older (& failing) RVS4000 v1 with a new V2. I need to minimize downtime. Will a config backup from the old v1 restore properly to a new v2 (all have newest firmware)? There are a lot of tweaks including several VPNs and to do it all manually is not desirable.

I have 2 Cisco routers 3945. Use HSRP for links failover. Does exist any possibility (any protocol) which makes routers configuration's automatic synchronization (as failover for ASA firewalls)? I mean, if I will make any configuration changes on the Active router, automticly will taken this changes by the Standby router.

Is it possible to have this setup on RV016?
WAN1: VOIP traffic (either by port or IP) + failover for WAN 2 WAN2: all other traffic + failover for WAN1 WAN3: failover for WAN1 & WAN2 with connection on demand

I have an issue where we have a single ASA5505 [soon to be active/standby with single ISP] connecting to HQ where there are 2 x Cisco 2821's. Each 2821 router has it's own connection to the internet running BGP and each router is setup to terminate IPSEC VPN's from the ASA. The ASA has a backup VPN configuration with no IP SLA configuration to track if the Primary IPSEC endpoint is alive. Keep alives are set and the VPN does failover to the backup.When the primary 2821 internet connection fails the ASA fails over to the backup 2821 and everything works a dream. However when the primary internet link re establishes to the primary 2821 the ASA does not fail back to the primary 2821 it stays on the backup 2821 and all is broken as the remote site starts forwarding traffic out the BGP default route - which is back via the primary connection...How do I fix this so that the ASA tracks the IP of the primary router to failback without manual intervention - clearing isakmp and ipsec sa's?The other issue is the ASA does not allow traffic to be orignated from the 2821 end of the VPN. You have to establish traffic from behind the ASA for the IPSEC sa to be created.

I'm looking to use 861s at few remote sites connecting to a 881 in the main office using Easy VPN. If I was to get 2 ISPs at the main office, can I configure it in a way that if the primary WAN failsover to the secondary, the VPN tunnels from remote sites will also failover?
Would you recommend an ASA 5505 at main office over the 811?

I upgraded my Linksys RV042 firmware to 1.3.12.19-tm and exported the config file, then tried to convert it using RV0xx_Migration_Utility_v1.0.2.2 in order to import it to a new Cisco RV042 (v3). The migration utility returns a config create fail message and fails to convert.
The LOG file ends with:
Get PORT_101 VLAN Group setting fail.
***log end***
how to make this work or how to move config file to v3?

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.

I was wondering how does failover works on Cisco Small Business RV016. Specifically, I am interested when one WAN line stop working, and all the computers in the LAN start using another line. Does it means that IP addresses of the computers in the LAN will change, or they stay the same? If they change can I set it up that they always stay the same no matter which input WAN they are using?

RV042 in Router mode.WAN1 preferred.With Smart Link it seems to work to a point.When WAN1 fails, it fails over to WAN2.But then it gets stuck on WAN2 and I have to manually switch to WAN2 preferred and then back to WAN1 preferred to get WAN1 connection to return.The test IP addresses should be just fine as set.
Is there something I should be doing differently?

Signed onto pc as admin, logged into router with correct user name and password. No page in the browser based configuration displays the complete information for the page. Menus are missing as are option labels, etc. The last time I accessed the router (about a year ago) I didn't have this problem.

Have a 1921 that has 3 eth connections (1 LAN, and 2 WAN) - I have 2 seperate OSPF processes (2 areas) on the WAN Ints - both upstream WAN's are sending defaults back to the 1921, and the 1921 is sending it's LAN range to them.
I have ip ospf cost 150 set on the "failover" WAN connection interface (Both on the 1921 and upstream), but the 1921 is preferring the default route from the "failover"?
The default routes are both being received by the 1921, but it's preferring the "failover" Int with the ip ospf cost 150 configured?

I am building a site to site VPN from our headquarters to a customer. I am using an ASA 5520. The customer is using Cisco 3945 routers. The customer has two VPN termination points. The customer requests that we make one of their termination points the primary VPN connection and make the other termination point the backup in the event that the primary VPN fails. How do I configure this on the ASA? Does the below configuration fulfill this goal?

I'm running into and interesting issue concerning a twice NAT config.
We have a remote site that needs to connect to a server cluster on our end. Using ASDM I have created a NAT rule that uses PAT to map our server addresses to a single IP (this is due to constraints placed on us by the remote site). This in and of itself shouldn't be a problem. The issue is that the VPN tunnel won't come up unless I also map an address to the remote site's sever.
Example:
Appliance: ASA 5510
ASA Version: 8.4(2)
ASDM Version: 6.4(5)
Original Packet:
Source Interface: inside
Destination Interface: outside
Source Address: Server_Cluster
Destination Address: Remote_Server
Service: any
Translated Packet:
Source NAT Type: Dynamic PAT (Hide)
Source Address: Mapped_Server_Cluster_Address
Destination Address: Mapped_Remote_Server_Address
Service: -- Original --
Within the Translated Packet section, if I set Destination Address to the actual remote server address nothing happens when I attempt to bring up the tunnel. However, if I map an address to the remote server, the tunnel begins to come up and then fails during phase two (as the mapped address doesn't match the addressing that has been defined in the remote end's connection profile).
Initially I thought the issue may be due to an IP addressing overlap since both sites are running similar numbers, but the default route statement on our ASA, should contend with this issue. Also, each time I change the NAT rule, I change the connection profile to match those changes.
So, ultimately, what I wish to accomplish is to allow connectivity between my site and the remote site without having to map another address to their remote server. How may I do this?

I have 2 office buildings using Cisco 800 series routers with a L2L VPN between both. I'm upgrading the router to an ASA5505 at one of the offices but can't figure out the L2L VPN on the ASA. Specifically, can't figure out how to set the pre-shared key. On the Cisco 800 it's:That doesn't seem to work on the ASA. Here is my current config on the Cisco 800. [code]

I am converting one PIX config (in 6.2) format to 8.4 format manually.I am stuck at the following statements.
---------------------------
global (outside) 1 192.168.21.100-192.168.21.150 netmask 255.255.255.0
global (outside) 1 192.168.21.44 netmask 255.255.255.255
nat (inside) 0 access-list 101
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
access-list 101 permit ip host 10.130.101.2 10.132.102.0 255.255.255.0
-----------------------------
My understanding from the old config file was that any traffic coming from source 10.130.101.2 to destination 10.132.102.0 would NOT be translated and this shall remain the same in 8.4.How can I rewrote the NAT commands?

If I have a PI 1.2 system that has multiple interfaces configured I can upgrade to PI 1.3 and both interfaces remain and I can see both under the admin webpage under appliance interfaces. But if I do a fresh install of PI 1.3 I can only configure one interface. The commands fail from the cli to configure anything but gigabitethernet 0. Are multiple interfaces not supported in PI?

I'm working on tweaking the config on a 2911 ISR G2 with a ZBF and am looking for some input. Our main issue right now is that the router is having performance issues once we hit certain troughput thresholds.
Right now, I have an inside-outside inspect set to look at all FTP, TCP, UDP, ICMP, DNS, SIP and HTTP (I know, its a bit redundant) traffic and do inspection on it then pass all other traffic. From a company policy, we are not filtering ANY traffic of any kind going outbound. (I know this isn't best practice but that's another battle for another day.)
Additionally, I have an outside-inside policy set to pass GRE traffic to an internal PPTP server (I know, not secure but its what we have.) then I have another inbound policy to inspect all traffic coming through that matches a specific ACL that defines all of the holes we're poking for hosting various functions on internal servers, etc.
could I, should I, why would or wouldn't I simply pass traffic that matches specific ACLs or whatever instead of how we are presently doing a lot of inspection?If I was to simply pass matching traffic instead of doing the inspect, would I see a substantial performance increase/workload decrease ont he 2911?
What are the security ramifications related to simply passing traffic instead of doing the inspection?

I have a task for a config I have not done before. I'm replacing an older 831 and PIX with a Cisco 881 router with Firewall feature set. The router receives its public IP address dynamically and there is a static public IP range also assigned with a couple of NAT statements on the PIX for a few public IP's.I'm ok with the core router config but the range is where I'm a little stuck. Current setup is as follows
Internet ---------- Router( Public intf Dynamic IP----internal intf Range IP)Router-------------PIX (outside intf Range IP---------Inside intf private net)Pix-------
As per the aboive the PIX had a public IP address from the range on the outside interface with a default route to the Router inside interface which uses a public range addres.
With my proposed config I've setup the outside interface as dynamic and just created my nat statements for the Range IP's. I believe I'm correct that I do not need to actually have a Range IP address configured on the router?
