I have setup ipsec VPN in my C2811 router but when "show crypto isakmp/ipsec sa" shows nothing. Remote end point is an "ASA5520". Does it indicates that the remote ASA5520 not yet configured?

i repalced old cisco router 2811 with new one 2921 , all works except crypto map VPNs routers can ping each other , ACLs are not applied to outbound interfaces show crypto isakmp sa is empty after i make same configuration on a new router 2921 config crypto isakmp policy 10
hash md5
authentication pre-share
crypto isakmp key key address Y.Y.Y.Y no-xauth

keys match , crypto isakmp policy is same , IOSs supoort VPN .interess traffic alse been initiated from both side and all worker in old cisco router with same configuration?
In a basic VPN l2l scenario using ezVPN, server behind NAT device, client using 3G. What would be the reason to have in the output of the show crypto ipsec sa, a current peer different from remote crypto endpoint on the server ?

My router tells me that he does not know crypto isakmp.
I searched on the internet and found that i have to install a specific license, but unfortunately i cannot find which license i have to install.
The show license command show following licenses
AdvIpServices active
AdvSecurity active
advsecurity_npe, ios-ips-update, waas_Express no state displayed
ssl_vpn active but eula not accepted
I found that i can accept the eula license with license boot module c880-data technology-package SSL_VPN command
But this command is also not available on my device. getting the crypto isakmp command working?
I have a Cisco 881 ISR (CISCO881-SEC-K9) and have the advanced security license installed and enabled/active and in use (see screenshot). However, the isakmp crypto module is not available.

Just looking at a new clients setup and they have a ISAKMP vpn to the old security company I am trying to remove...I am fairly new to cisco, I actually know how to setup the ISAKMP policies, acl's etc but never had to completely remove one before All I can find is Clear Commands which seem to just flush the config not actually delete any of the policy etc...Its not that urgent as all passwords are changed on the domain and the cisco, the usernames have been deleted as well.

I have been looking around and I can not find the " crypto isakmp policy " command on this Cisco Router 1941. I just wanted to setup a regular IPSEC Lan to Lan tunnel and surprise, the command is not there. Do I have the wrong IOS? I thought that a K9 image would do the trick. [code]
View 2 Replies View Relatedrecently we had some performance issues with C2811 which caused us to do some lab testing. For testing we used also C1812. The results were quite surprising for us, as the C1812 appeared to be more efficient than C2811. Below you can see the lab scenario and results.
1. Why C2811 is performing worse than C1812?
2. Is there any official Cisco reference stating what are the max VPN throughputs of certain platforms/models? (we consider migration to C2900 platform and would like to choose the right model)

I am currently experiencing an issue with an IPSEC Tunnel between a Cisco892-K9 (c890-universalk9-mz.124-22.YB.bin / Feature: advipservices) and a Checkpoint VSX R67.
After reloading the router the tunnel is stable, but afterwards we loose the connection to the LAN unexpectidly (max. time of the connexion is ~2h30).
In fact after a reload the first ISAKMP SA is well negotiated with conn-id 2001 and after a certain amout of time the connexion is lost always associated with this debug message =>
ISAKMP:(2001):error from epa_ikmp_gen_ipsec (QM_IDLE )
ISAKMP:(2001):Unable to generate IPsec key for 799280698!
ISAKMP:(2001):deleting SA reason "Death by retransmission P2" state (I) QM_IDLE (peer 194.X.X.X)
and so on ....
We supposed it was related to DPD messages so we deactivated the keepalive (no crypto isakp keepalive). We tried to play also with the ACL matching the crypto map (currently from local subnets to any), but still no luck.
When it is stable the ‘show crypto isakmp sa’ indicates a isakmp sa ‘QM_IDLE / ACTIVE), and when the problem occurs the active ISAKMP SA is deleted and recreated (in ACTIVE state) continuously : conn-id 2001, 2002, 2003, 2004 etc...…but still no access to the LAN.
My main question is to know if someone has already know the signification of the previous ISAKMP debug messages (along with the total debug message + crypto conf from the beginning of the problem) =>May it be a platform support (near 200 ipsec flow in use => most subnet to subnet flow, few subnet to host flows- 200 users on site) , compatiblity, crypto map acl …???
I have installed a new 2901 router with the IOS version 15 code (c2900-universalk9-mz.SPA.152-3.T.bin). I have a template config that I have created for my remote VPN routers that I have been using on 2811 routers with version 12.4 (c2800nm-advipservicesk9-mz.124-24.T1.bin).I do have the securityk9 active on the 2901 software

Issue is when I do a "show crypto session" the GRE tunnels session status read down on the 2901 router but on the 2811 session reads up-active. Everything is working and I am routing over the GRE Tunnels.

My router is Cisco 2811 with IOS version 12.4(22)T1. It had established IPSec with another peer (203.*.*.250 shown below) for long until recently we make it re-establish IPSec VPN with another peer (203.*.*.30 shown below). It showed that the new sa is active but the result still showed there were 4 deleted SAs. The 4 obsolete sa entries won't vanish no matter what I do i.e. reset the interface, re-create crypto map, clear all sa and etc.
From numerous testings we knew that the VPN doesn't work even the desired sa is there remaining active. I reckon it has something to do with those deleted sas ( i mean it is supposed to show only the last one if it is working fine ). I don't know how it would be come like this as we did pretty much the samething on other VPN routers with no problems.
im drawing a blank trying to setup a site to site connection with a 5505 ASA using ipsec and isakmp.i have the pre shared key as well as the external address of the other end of the tunnel but do not remember what the commands are to setup the crypto map and isakmp.

View 3 Replies View RelatedI have an office c2811 and it has three Ethernet interfaces(two onboard and one expansion). Faste0/0 is on one isp and faste0/1 is on another. The third is private. I have multiple site ipsec vpn’s terminating on faste0/0. I had a client ipsec vpn on faste0/1. One of the site vpn’s on faste0/0 terminates at a collocation site. Both the site vpn and client vpn need access to the same collocation. When I connect via client vpn, I cannot ping/access collocation subnet. I suspect this is because I have a site vpn already terminating to the collocation. Can I have a site and client ipsec vpn on the same router terminating to same place and still work?

Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.
