I'm trying to setup a GDOI based IPsec connection between a cisco AS901 (advanced Metro lic - asr901-universalk9-mz.152-2.SNI ) and a 7606-S.What I see is that the ASR901 is capable of decrypting the IPsec packet but I cannot encrypt the ICMP packet back, so the question is if the AS901 can support IPsec in software. What I could not find in the docs on CCO. [code]
View 1 RepliesFor a customer we want to deploy the Cisco ASR 901 and connect them to a E1 unframed connection. However I don't see in the documentation that unframed is described and I was wondering if the Cisco ASR 901 is supporting E1/T1 in unframed mode? [URL]
View 1 Replies View RelatedI have RSTP rings consisting of Alcatel 7450's and Foundry FES switches. I want to insert Cisco ASR901's into these rings and have been testing in the lab. It appears that the ASR901's only support MSTP in the EVC configuration. So I would prefer to keep RSTP on the Alcatel and Foundry's and enable MSTP on only the ASR901's.
Topology is:7450-2 <=> Foundry-2 <=> ASR901-2 <=> Foundry-1 <=> ASR901-1<=> 7450-1 with a VPLS between the 7450's.
If I enable MSTP in the Foundry's, Alcatel and ASR901 everything works fine. If I keep RSTP on the Foundries and 7450's, then STP also works, with the exception of a Foundry-2 switch running RSTP, that is located between 2 ASR901's running MSTP. This switch does not seem to interact with the other switches (i.e. thinks it is the root bridge).Since there are mulitple MSTP boundary's, do the ASR901's need to be in different IST's/instances?

This has to be the most weirdest issue I have seen since the past year on my ASA. I have an ASA 5540 running the 8.4(2) code without any issues until I stumbled upon this problem last week and I have spent sleepless nights with no resolution! So, take a deep breath and here is a brief description of my setup and the problem:
A Simple IPSEC tunnel between my ASA 5540 8.4(2) and a Juniper SSG 140 screen OS 6.3.0r9.0(route based VPN)
The tunnel comes up without any issues but the ASA refuses to encrypt the traffic but decrypts it with GLORY! below are some debug outputs, show outputs and a packet tracer output which also has an explanation of my WEIRD NAT issue:
My setup - ( I wont get into the tunnel encryption details as my tunnel negotiations are **** perfect and comes up right off the bat when the ASA is configured as answer only)

As you can see, there is no echo reply packet at all as the packet is not being encapsulated while it is being sent back. I have been going mad with this. Also, this is a live production multi tenant firewall with no issues at all apart from this ****** ip sec tunnel to a juniper!!
Also, the 192.168.10.0/24 is another IP Sec tunnel remote network to this 10.2.4.0/28 network and this IP SEC tunnel has a similar Juniper SSG 140 screen os 6.3.0r9.0 at the remote end and this woks like a charm without any issues, but the 171 is not being encrypted by the ASA at all.

I have made some test and i noticed that qos input policy does not classify the icmp packet based on their dscp.The "match dscp ef" or "match precedence 5" is not working only the "match protocol icmp" shows hits.
We need to classify the different icmp packets based on dscp ( TOS ) for measurement purpose.CISCO 7200, 12.4.25d and 12.4.20T have a same behavior.

View 2 Replies View RelatedI need to set up several L2L ipsec tunnels using ASA 5540 (8.2) as a central node and ASA 5505s (8.4) for branch offices. So far I've configured ipsec for the sake of testing between a 5540 and one of 5505, but it blocks ICMP between hosts behind ASAs. Although there's an echo response from 5540's inside interface (172.30.0.1) to echo requests from a host behind ASA 5505 and I see ipsec counters growing. I still can't figure it out despite hurting my eyes with cisco manuals for the relevant ASA software versions.
One thing I couldn't understand in the 8.4 documentation - it says I need ACLs to allow ipsec traffic on outside if I don't NAT/PAT it. Isn't it achieved with "sysopt connection permit-vpn" or do I have to do it manually? I've actually tried adding access-groups for the "in" traffic on outside and those ACLs get hits on both ASAs.
The packet-tracer shows some weird DROP at phase 6 on 5505, but I see no rule denying this traffic and the description doesn't mention implicit rules. [code]

I can see that the packet count is increasing both inbound and outbound on the ATM interface. I have read many documents and tried many different way to try and get this resolved, I even logged a call with Cisco but no dice.
I have a 1841 router connected to an ISP (currently SDSL EFM 10Mbps through an ISP modem, the router and the model are connected with a FastEthernet interface). On another location I have a linux server.There is an ipsec tunnel (3des-sha esp) between the router and the linux server (actually done with a crypto mac).The router has a hierarchical QOS policy on the egress interface.When sending traffic from the network inside the router to the linux host without the ipsec tunnel, everything is working fine and throughput is correct.When sending traffic from the inside network to the linux host internal ip through the ipsec tunnel, some packets are lost and the traffic throughput decrease.When sending traffic through the tunnel in the reverse direction (from the linux host to the internal network), everything is fine.I looked at the QOS statistics and the dropped packets counters don't increase. I looked at the egress/ingress interface statistics and no packets dropped there.I lowered the MTU on the egress interface, but it didn't solve the problem. I played by sending various ping icmp packets size, but even small packets are sometimes lost.I tried to check the router CPU, but it seems relatively fine (<= 10%)I captured the traffic on both side, and I see the packets emitted, and then I can see that some of the esp packets of the corresponding side are not received, so it looks like the cisco router is the culprit. This 1841 router is running: 1841 Software (C1841-ADVIPSERVICESK9-M), Version 12.4(24)T4,How can I troubleshoot where and why those packets are lost?

View 3 Replies View RelatedI'm trying to troubleshoot a random packet drop issue for an IPSec tunnel between two VTIs. For over a month, we didn't see any issue, and starting today, we have up to 30% packet loss across an IPSec tunnel.
After some analysis, I concluded that the packet loss happens somewhere on the path from the uc520 to the 2921. Packet counts show up correctly on the uc520 physical egress interface, but the packet count is low on the ingress interface on the 2921.
Pings outside the tunnel along the same path are fine.
I also cleared the tunnels on both ends and after they reestablished, the issue was still present.
Any pointers on finding where the packets get lost?

I need to implement IPv6 for ASA VPN. According to the ASA_8.4_cli_cfg.pdf , IPv6 is not supported on ASA IPSEC vpn and remote client vpn. I do not have a ASA 8.4, any way to verify on ASA8.4 whether the crypto command support ipv6 address ? If the crypto command do support ipv6 address then probably there is chance it will work.what i mean is eg. crypto map xxx set peer <ipv6 address| ipv4 addres> able to set ipv6 address.
