Cisco Switching/Routing :: IP SLA Support On 1921/K9 Or 1921-SEC/K9?
Oct 5, 2012We want to puchase new Cisco ISR 1921/K9 . i want to know does it support the following sample IP-SLA commands
ip sla 2icmp-echo 172.16.1.2timeout 500frequency 1ip sla schedule 2 life forever start-time now
track 10 rtr 1 reachability
delay down 1 up 1
!
track 20 rtr 2 reachability
delay down 1 up 1
ip route 0.0.0.0 0.0.0.0 192.168.1.2 track 10ip route 0.0.0.0 0.0.0.0 172.16.1.2 track 20
Im asking above question because we will need to enable ip-sla on the mentioned router. as i read on the cisco webside, it says Cisco-ISR-1921/K9-IP Base support only IP-SLA RESPONDER feature nothing else. If Cisco-921/K9 does not support the above commands , should i go for ordering Cisco-1921-SEC/K9 ?
Cisco WAN :: 1921 - Route Between VPN Tunnels
Jul 7, 2011I have a Cisco 1921 and it has 2 VPN IP-sec site-to-site tunnels up and running. Lets say the tunnels goes from the Cisco to Site A and Site B.
Now i want Site A to reach Site B through the existing tunnels. I'm guessing that static routes maybe the answer but i cant seem to get it working.
The LAN networks is as follows:
Cisco: 192.168.15.0/24Site A: 192.168.0.0/24Site B: 10.27.27.0/24
At Site A i have set up a static route as follows:
Traffic destined for 10.27.27.0/24 Go to gateway 192.168.15.1 (the default gateway of Cisco LAN)
At Site B i have set up a static route as follows:
Traffic destined for 192.168.0.0/24 Go to gateway 192.168.15.1 (the default gateway of Cisco LAN)

Nov 4, 2011I need to create multiple ip-sec vpn tunnels on A Cisco 837 ADSL Router. I am able to create one tunnel but the second connection is asking for the outside interface which is atm and already taken by the first tunnel. How can i create more tunnels?
Secondly, after creating the first tunnel i am able to access the remote lan network but when i tried tracert "remote lan ip of a pc" from my pc i got "request timed out" after passing my 837 but succeeded to reach the target. Does tracert needs something to be opened in the router?

Cisco VPN :: IPSec Tunnels Between ASA 5510 And 5555
Nov 13, 2012I have an ASA 5510 running ver 8.0(2) that has (4) Ipsec tunnels going from it to various other locations. I am having an issue with data transfer speed on only one of the Tunnels. This tunnel is between the 5510 and the 5555, on that link I am getting a dat transfer rate of a little over 120k a second, whereas if I pull the same set of files from another location I am seeing a transfer rate of 5m per second.
I have verified that it is not a capacity issue on the Internet bandwidth on both locations, and I can pull the same data from the same location to various other locations via Ipsec tunnels, I am only having an issue with a specific tunnel going from the 5510 to the 5555.
Since it is not affecting other tunnels on the 5510 nor is it affecting tunnels on the 5555 going to other locations, I am leaning toward a routing issue within the ISP? I will say the ISP is taking me a long way around to stay in the same Metropolitan area.
Cisco :: IPSec GRE Tunnels And Traditional Site VPNs
Mar 21, 2011I've been reading this site for a while, and finally decided to post I'm really interested to see what everyones opinion on this is.My company currently uses what i would call traditional site to site VPN's using crypto maps, main site has a pair of ASA's in HA and remote sites use ISR's like 1801's.I've recently been playing in my lab with GRE tunnels using IPSec protection (note this is config from my labs, so ip's and key's are just randomly selected)

View 0 Replies View RelatedCisco VPN :: ASA5510 - Slow Traffic On IPSec Tunnels
May 2, 2013We have many VPN tunnels back to our corporate office. All of these tunnels are very slow (same with our client VPN's). Our main firewall device at the corporate office is an ASA5510. We have a 100 Mb/sec Metro Ethernet internet connection here. We do not allow split-tunneling.
Our remote sites vary. We have DSL connections, cable internet connections, and other types of broadband that vary in speeds from 5 to 100 Mb/sec (up and down). The remote sites mostly have PIX 501's, but we have an ASA 5505 in one of the locations.
To take an example. On one of our remote sites that has a 100 Mb/sec connection, if I ping device to device, I'm getting ping times of about 50ms. And I'm pinging back through another 100 Mb/sec connection. If I get on a computer down there and run a speed test, I'm showing down speeds of about 1.5 Mb/sec... nowhere near 100. Some of that could be due to the lack of split tunneling, but I also suspect this could be an MTU issue.
Right now, all my MTU's are just set to the default 1500. Perhaps this is too high. I used this site to check my max: [URL]
I did a few tests from behind several of my firewalls. I pinged from a machine on one side of the tunnel to the firewall on the other end. I'm assuming the max MTU I come up with is the max MTU for the firewall I'm behind while pinging, right? The max amounts I came up with for some of my devices were as follows: Corporate ASA 5510 > 1272 (if you add the 28 byte packet header that would make it 1300) Remote PIX 501 > 1416 (if you add the 28 byte packet header that would make it 1444) Remote ASA 5505 > 1418 (if you add the 28 byte packet header that would make it 1446)
So, do I just need to set my MTU values to the appropriate amounts? I have tried changing the value, but I don't see any change in speed/performance. But I also don't know if I need to reboot the firewalls after changing the MTU. I know with Catalyst switches, you have to reload. But I didn't see any messages about needing to reboot on the ASA's/PIX's.

Cisco VPN :: 2801 - Unable To Route Traffic Over IPsec / GRE Tunnels
Jan 12, 2013I have an issue where I can get traffic to pass from HDQ to two branch offices over our ipsec/gre tunnels even though the tunnels appear to be UP. The HDQ is a 2811, branch is a home office using an 871W and branch runs a 2801 router. I initially had HDQ working fine with the 871W but when I configured branch2 (2801), they both broke. The tunnels appear to be up but traffic is not routing across them. The two 2801 routers run 12.4 (c2800nm-adventerprisek9-mz.124-24.T2.bin). These are gre over ipsec tunnels. Currently traffic flows over an exsting MPLS network that we are getting away from due to cost. As soon as I change the routes to point to the Tunnels, it breaks. Traffic doesn't appear to pass through the tunnel. I have attached my sanitized configs.

Cisco Switching/Routing :: 881 - IPsec VPN Tunnels / Ping From Workstations
Sep 25, 2012We have a number of sites running Cisco 881 routers. A few of the sites are connected by IPSec VPN tunnels that have been configured using Cisco CCP without any issues until now. On one location I can ping from a workstations on Site1 to Site2, however I cannot ping from the same workstation on Site2 back to Site1.
Here is a strange behavior. If I have a continuous ping going from Site1 - Site2 and then start a continuous ping from Site2 - Site1 then I get a response until I stop the ping from Site1 - Site2. Site 1 has approximately 5 successful tunnels with absolutely no issues.
Here is some site specific Info:

For additional troubleshooting I established a VPN tunnel from Site2 to our office Site3 with no issues at all. Site3 happens to be one of the VPN tunnels that connects to Site1 with no issues. I have seen a number of articles on this on the net and gone through the troubleshooting steps of an article such as [URL]. The tunnel is confirmed as up when I have done all my troubleshooting.

View 2 Replies View RelatedCisco VPN :: 1921 - No Local Network / Internet While On IPSec VPN
Dec 28, 2011I am testing a EasyVPN IPsec server set up on a cisco 891. Here is how I have it set up right now- the 891 is connected to our backup internet connection (different ISP from our main line) and we have a cisco 1921 as our production router.
I am experiencing a problem where when I am on our internal network off the 1921 and I connect to the VPN on the 891 I lose all local network connectivity. Nothing works, can't ping, can't telnet to the 1921, can't browse the internet, its not just DNS either.
I believe the issue lies in the configuration of the IPSec server on the 891 because when I connect to our client's cisco IPSec VPN I experience full local connectivity with no issues whatsoever. It seems to me that ALL traffic is being routed through the tunnel.
Other than the local issues the VPN is working fine and I can remote desktop to the PC I have set up off the 891 and telnet to the 891 from there.

Cisco WAN :: 1921 And VWIC3-2MFT-t1 Support?
Mar 7, 2013I was just given a task to setup some T1 connections. We rarely use T1 interfaces anymore as they are typically just not enough anymore. I see the newer vwic3 interfaces are supported on various 2900 series but downloaded the vwic3 configuration guide and noticed that the 1900 series routers were not in the list? Is this correct. So are vwic3-2mft-t1 ehwic cards supported or not on 1921 routers? i can see the controller interfaces but not the ports as there must be additional configuration required. Im running 15.1(4)M4 IOS version that looks to be supporting the cards.

Cisco VPN :: Multiple Site To Site IPSec Tunnels To One ASA5510
Dec 4, 2012Question on ASA VPN tunnels. I have one ASA 5510 in our corporate office, I have two subnets in our corporate office that are configured in the ASA in a Object group. I have a site to site IPSEC tunnel already up and that has been working. I am trying to set up another site to site IPSEC tunnel to a different location that will need to be setup to access the same two subnets. I'm not sure if this can be setup or not, I think I had a problem with setting up two tunnels that were trying to connect to the same subnet but that was between the same two ASA's. Anyways the new tunnel to a new site is not coming up and I want to make sure it is not the subnet issue. The current working tunnel is between two ASA 5510's, the new tunnel we are trying to build is between the ASA and a Sonicwall firewall.
