Cisco WAN :: 1841 - Configure VPN For Failover On Router?

View 5 Replies View RelatedCisco WAN :: 1841 / Router ISP Failover Feature - IP SLA
Feb 13, 2012I got a simple office: one flat LAN, one single 1841 router and 2 ISPs.LAN is 10.10.20.0/24 and is connected to a port on an HWIC card I installed in the 1841. Then FA0/0 connects to ISP1 and FA0/1 connects to ISP2.
Everything is fine except that I am having some issues with the Failover feature. Currently, I am using Object Tracking with SLAs. I am pinging 2 hosts located on the internet and then I have an SLA OR statement which basically say if ANY of the 2 objects are unreachable, DO NOT trigger a failover to ISP2. If in the case that BOTH objects become unreachable, then DO trigger a failover. It works like a charm.
The problems:Any internet hiccup obviously makes the router activate the tracks and redirects all traffic to ISP2. However, 99% of the time ISP1 is back online within minutes or seconds, so after 180 seconds the traffic gets redirected back to ISP1. So in essence, the customer suffers 2 interruptions.
Besides internet hiccups, I have also noticed that every time any user tries to copy a big file accross the tunnel (the 1841 has site to site tunnels with 2 branches) the tracks go crazy and the objects become unreachable so a failover is triggered. We were breaking our heads and fighting with the ISP1 provider because every time this happened, we called them but every time they kept telling us that their line was UP and running without any problems. So after careful investigation, I do admit they were right.... it is not so much that the ISP1 experiences hiccups, it is actually the fact that users putting heavy load into the router are causing it to have its track to stop reaching the objects.
Cisco Firewall :: 1841 / Failover Between Leased Line And VPN
Jul 15, 2011I am going to design one network. I had queries with this design.Let me explain scenario first( it was attached below).I have two sites, Site-A and Site-B, repectively.
In site-A i have one Cisco 1841 router, one Cisco ASA 5510 firewall and One cisco 3560 layer 3 switch.
in site-B i have one Cisco 1841 router, one Cisco ASA 5505 firewall and One Cisco 3560 layer 3 switch.
From ISP side
I have point-to-point leased line between sites A and B. And both sites have internet connectivity from another ISP.
I planned to terminate leased line in cisco 1841 router in both branches for branch to branch connectivity.
I will configure site to site VPN between two sites, A and B.
Here my query was i want make VPN as failover connectivity if leased line fails. In both the cases, i need internet to the inside users in both sides.
Summary requirement:Leased line is Primary and VPN is Back-up, if leased line fails. In both cases internet is needed to inside users.
Cisco WAN :: Failover Between ISP Router ASA 5520
Aug 24, 2011I'd like to configure HA between an ISP router and a firewall ASA like shown in the document. I was thinking about HSRP but can I use HSRP between a router and a firewall?Another information.I have 1 asa 5520 on my site connected to an ISP 1, and a second asa 5520 at a second ISP's datacenter. My aim is that if the 2nd ISP is not available, all trafic go through the asa on site and to the first ISP.

Apr 1, 2012All- we have a client that has a data center in Boston and a DR in New York with more than 10 site-to-site VPN tunnels. Each remote site runs IPSec with GRE tunnel with BGP connected to the Data Center in Boston. The client requests to build the failover VPN router at DR in New York, and between New York and Boston, there is a MPLS via eBGP.
I am attaching the network diagram. Should I run the same AS 65003 on the failover VPN router 2 as the router 3 since the router 2 and 3 are VPN terminated end points? or should I run the different AS than the AS 65003?
Cisco WAN :: When Creating Failover Setup Cause 1800 Router To Hob Away
Mar 20, 2013I have been given a task, where I need to create a failover setup from a 1800 Cisco router to a LAN network 2 hobs away (see topology).The reason I have been given this task is because the wireless links are not so realiably, but necessary.I'm thinking of doing this failover task with IP SLA on the routers fiber 1 and fiber 2 link, so when/if one off the links goes down, it instantly chooses the other link.I have also been thinking about implementing STP instead, and replace the router with a switch, but i'm not sure exactly how to implement it. Unfortunately I'm not able to test anything, as we are still waiting for the fiber lines, but I want to be prepared as much as possible.

Feb 4, 2013Leased line is between dammam to dubai and the dammam office is getting internet from dubai.The ip address of Dammam office is class A (Public IP) x.x.x.x and for dubai it is y.y.y.y which we are using as proxy for accessing internet.I purchase the local DSL direct line connection through cable from Local Provider and this ip address range is 192.168.1.0 - 192.168.1.254.Is it possible to use the DSL line as failover, so if one line goes down the user should remove proxy and can use local internet.The router which is using is cisco 1800.
I believe that failover is possible, 100%, but would like to know how I can do it and requesting for sharing more inputs about failover in this case.

Cisco WAN :: 1841 BPR With Router And Firewall
Oct 20, 2012In my company, we have two Internet connections, one for VPN and the other for emails and browsing. I have Cisco 1841 router with dual ADSL links, and also it's conntected to ASA and the other PIX. through one physical interface (vlan 1and vlan 2). The PIX firewall is connected to users, and the ASA is for VPN only.How can I seperate the traffic is going for emails and browsing and the vpn traffic. I have got to the point, that the router is configured for both ADSL connections, and I also configured the access-list and route-map in the router, the thing is when both ADSL configured together none of them works.

Cisco WAN :: 1841 Router Is Not Responding?
Mar 18, 2011I have a Cisco 1841 router equipped with a serial interface and an ISDN BRI interface installed.The router has stopped suddenly responding and no display is beig obtained when trying to access the router through the console port.I have check the router LEDs and they display the following:
SYS PWR - It is showing solid green which means the router is receiving power, and the internal power supply is functional. It is not blinking green as is normally the case when the router is rebooted.
SYS ACT - It is showing solid green. It should normally be blinking green showing that the system is actively transferring packets and monitoring internal activity. CF - It is showing solid green. It should normally be off indicating that the CompactFlash memory card is not being accessed or be blinking green showing that the CompactFlash memory card is being accessed.
I have even replaced the CompactFlash memory with another one and removed the two WICs installed but the router still fails to initialise properly and respond through the console terminal program. how the router can be further troubleshooted or if it can be repaired?
