Cisco Firewall :: ASA5585 State Link Supported Over MPLS?
Jun 29, 2011
Running ASA5585’s in active/standby across a local campus MPLS network. Supported design, leading practice etc. Specifically our design is that two ASA5585 are configured as active/standby through a local campus MPLS network over 10gig links through ASR9k etc. The ASA’s are providing inter-vrf routing capability only with p2p l2vpn circuits configured for each logical interface between the ASA over MPLS etc.The failover link is via a direct fibre and the state link will be through a p2p l2vpn (option for direct fibre also)Is this a supported design to begin with?

we just purchased 2 asa 5585-40's and tried to add them to our lms 3.2 system and we were informed by cisco tac that they were not supported in lms 3.2. since we don't having funding for an upgrade, any work around within lms that could allow me to add the devices so i can use lms for syslog and to fetch the firewall configs on a regular basis, instead of having to setup a seperate syslog server and having to tftp the config's everytime i make a change.

I am interesting how ASA 5585-X with SSP-60 operates in dual firewall mode, if I install two SSP-60 modules in chassi, do I get one logical firewall with doubled performance of (SSP-60) ?

I have put 2 physicl interfaces (te0/8 & 9) on the ASA-5585 into a PO and am assigning ips/vlans to the sub-interfaces. I have 2 issues: - Why am I not able to ping the other sub-interface from the ASA itself? (I can ping the 1st one), Secondly, why the IPs are not visible in "sh int ip brief" ?Although I can see them in "sh ip" ..
/actNoFailover(config-if)# int po17.100
/actNoFailover(config-subif)# vlan 100
/actNoFailover(config-subif)# ip add

I am responding to a tender where the client is asking for the firewall to support an onboard disk drive for logging purposes, which is a minimum of 500 GB in size.
The other requirements all point towards the top of the range ASA 5585-X Chas w/SSP60,IPS SSP60,12GE, 8 SFP+,2 AC,3DES/AES.
I note the 5585 when configured on DCT comes with HDD blanking plates, is there an HDD supported on this?

However that still doesnt allow traceroute through for us. We still see syslogs with deny's on high level random UDP ports to different Internet destinations.

I got some issues with my CISCO ASA, the thing is that when I add a new rule on the device this rule duplicate and goes to the bottom. We already tried to delete the duplicate rule but it always show an error.
-Model 5585
-ASA Version: 8.2(5)
-ASDM version: 6.4(5)

I have ASA5585 Firewall between my WAN Cloud and LAN Network. I plan to configure Layer 3 Vlan Interfaces inside FW and it would be Layer 3 gateway for some of Subnets. Layer 3 VLAN Interfaces are planned to be dual stack containing both IPv4 and IPv6 Address stack.
I plan to configure 6 to 4 Tunnel with my Hub Site where we have native Ipv6 awareness. One tunnel end point would be ASA and the other endpoint would be Hub site WAN Router/L3 Switch. So IPv6 traffic hitting to vlan interfaces on ASA would be policy checked and routed over tunnel interface to Hub Site.
6to4 Tunnel manual tunnel configuration on ASA. I have configured such tunnel on L3 Switch or Router with following config.
Int tunnel xyz
ipv6 address <ipv6 address>
ipv6 enable
tunnel source <loopback address of my L3 Switch>
tunnel destination <loopback address of my hus site L3 Switch/Router>
tunnel mode ipv6ip
end
I need to implement something similar in ASA. How can I do that?

How do i measure the total throughput going via 5585-X.It has the firewall througput of 5Gbps. Looking at aggregate of all the interfaces traffic going through it seems about 4gbps is going through.
I use show traffic command and add up the trasmit and receive traffic on each live interface.Is that correct method and are there any more commands?

use of a pair of ASA 5585's in active/active mode with a shared outside interface.Last time I did this was with FWSM, there was a restriction where all contexts that share an outside interface have to be in the same failover group.Does this apply also to the ASA? My thought is that it will, but I am unable to find that in any documentation.

We're currently PATing everything from a particular subnet to the IP of an outside interface using our ASA5585 (dynamic PAT). We're experiencing pool exhaustion and therefore need to expand the global IP range. Any way of cutting over to the new range without dropping existing connections? For clarity, the current interface address is x.x.x.37/22 and the new PAT pool is x.x.x.114-6/22.

I have a ASA5585 running 8.4 that is redirecting Internet http to a websense server via GRE.The integration is working fine, except when a user PC sends a large packet (~1500 bytes).With WCCP/GRE headers, the user packet is too large to be transmitted to websense, so the ASA fragments the packet in two and transmits both to websense.
A sniffer trace confirms that both fragments reach the websense server, but the TCP packet is never acknowledged.User-side TCP retransmits the large packet three times over 15 seconds, and eventually retransmits fine with smaller packets. The 15 second delay is of course not acceptable.Users and Websense server are both on the Inside interface.
We are considering imposing browser proxy to websense (which works fine), but would prefer not, considering the increasing diversity of devices.

We are experiencing intermittent issues with the IPS on our ASA5585 vs 8.4(2). Probably something with the dataplane. So I want to keep debug cplane 255 activated and logged with log debug-trace setting to syslog server. But when session times out the debug command is cleared so the output stops. Since it is a intermittent issue I want to keep debug activated...Totally different behaviour then with routers which keeps it activated. how to keep debug activated on a ASA.

I have two ASA in failover with Active/standby configuration. When I switch from standby to active from the standby ASA I get a lot (like 100) of error messages like these below: [code] The failover works fine and nothing seems to be wrong with the firewalls function.
-Hardware is ASA5585-SSP-10.
-Software version: ASA 8.2(5),
ASA is in multiple mode with 17 active context. Why these error messages appear and what they mean?

We have pair of ASA5585 (ver 8.4(4) with IPS module configured with Active/Standby failover. There are total 09 interfaces are connecting to different zones in the firewall and out of which three(3) interfaces are connecting to Palo Alto 2nd layer firewall. When we test the failover whatever interfaces not connecting Palo Alto failed or shutdown, ASA triggers the failover to other unit, however the Palo Alto is not detecting this failover and it still keeps its previous Active Palo Alto to pass traffic, thereby failing passing traffic on Active firewall through Standby Palo Alto firewall.
But when there's a interface failed or shutdonw on the interfaces where PaloAlto also connected, then once the ASA failover triggers and the same time Palo Alto also trigger its failover then both new active firewall and Palo Alto sending traffic through firewall.However we we cant all the interfaces of ASA also to connect Palo Alto and let the Palo Alto to inspect all the interfaces, but we need our ASA to work in a situation where any of the interfaces failed, the failover to work smooth the pass the traffic via either Palo Alto device.I just need to know is there anything tricky that we can configure on our ASA in this failover senario, or to confirm if there's no any workable solution to this situation.
I have attached the senario that I explained above. Just to emphasis the issue again, if any interface of Gig0/0, Gig0/4 or Gig0/5 failed on active firewall, ASA switching to standby firewall and act as Active, but Palo Alto still remains his Active state and the new Active ASA is not passing traffic via standby PA as its not detecting any of its interfaces as failed or unreachable..?

I have two Cisco 6500 switches connected via fiber, this is my small network. One end goes to a provider, and the other end goes to a server. My IT department wants some sort of link state propagation since the provider keeps going down, but the IT team is unaware until they contact me.
We provide a Layer2 point-to-point circuit, access ports at the ends. We use V LAN's to transport the traffic. Please let me know if there is anything I could do to support link state propagation.

I have done a bunch of research in trying to re-use an old card/router for testing our new MPLS link. I have a 45m DS3 and was wondering if the PA-MC-T3= card will work UN-channelized. I have tried the "no channelized" command under the controller to no avail. I believe that the card only works for channelized T1's.

I have few inter-AS and Hub & Spoke MPLS L3VPNs up and running but, all of them uses plain IPv4 on the PE-to-CE connecting interfaces for switching the L3VPN customer traffic. While, this is ok to route traffic between customer sites over a ISP backbone using the VRF and MP-BGP/LDP configurations which does the MPLS forwarding in the ISP backbone, i would like to know, how to enable MPLS forwarding on the PE-CE links as well to make it MPLS right from CE1 - PE1 - P - PE2 - CE2 all the way for the VPN traffic.
This way, even the last mile access to CE devices will be an MPLS link over a Ethernet PHY so that, the traffic originating from CE1 to CE 2 will be carried on a MPLS tagged Ethernet frame instead of IPoEthernet frame.

I have been having a heck of a time trying to configure my 5505 to allow the second segment on my network to use the internet. Office 1 has a fiber internet connection, and all traffic flows fine. Office 2 had gotten it's internet from AT&T, via a network based firewall injecting a default route into the mpls cloud. both offices connunicate to each other through the mpls.
When we added the fiber to office 1, we had the mpls people change the default internet route to the inside address of the 5505 and things worked fine. when AT&T attempted to remove the NBF defaut route, and inject the 5505's address as default, things didn't go so well.
AT&T claims that it is within my nat cmmands on the 5505, but won't tell me anything else. I assume that they are correct, and I assume that I am not good enough with the 5505 ASDM to tell it what to do.
Office 1 uses 10.10.30.xx addresses and Office 2 uses 10.10.10.xx - the 5505 inside interface is 10.10.30.2 the internal interfaces of the mpls are 10.10.30.1 and 10.10.10.1

We have a ME6524 running as a MPLS P router. We want to mirror a port to capture a specific traffic stream (to a probe). As the port is an MPLS LDP port will this work, will both the VACL and SPAN work with MPLS tagged packets, or does the mirror and VACL work after the labels have been removed..?

I am putting together a solution for a client. The client has an MPLS circuit and internet as a backup circuit. I understand that we can do WAN failover using ASA5510 appliance.Now, if i am adding dual ASA5510 active/standby mode, How do i automatically failover WAN circuits to standby firewall if both MPLS and Internet circuits are connecting to primary ASA5510. Should i connect MPLS circuit to ASA1 and Internet circuit to ASA2? Ideally, i want both circuits to connect to primary ASA5510 for automatic WAN failover. My concern is , if the primary ASA5510 fails which has WAN and Internet circuits connected , do i need to manually switch connection from primary to standy? The goal is to fully automate wan failover and asa failover .

I am attempting to install an asa 5510 at my hq. Our MPLS network is provided by our ISP and the routers are managed by them. They will be working with me to add the needed routes to the routers. Using version 8.4.1 That said, here is my challenge:
I am connecting the MPLS routers and WAAS device to my core switch(also performing inter-vlan routing) in VLAN 2. There are 3 connections needed for the mpls equipment and they are all in vlan 2 on my core switch. The firewall (ASA 5510 with security plus licensing) also has an interface (outside) in vlan 2.
e0/0
shutdown
no nameif
[Code]....
configuration guides or suggest TAC as they have been a bit inconsistent with this issue thus far. What am I missing because I cannot get to where inside interface of the firewall is pingable by the lan and the outside interface of the firewall is pingable by the lan.

we have an ASR1002 running zone-based-firewall with 2 zones:
zone_ouside
zone_ph
I have a common ZFW-configuration on that interfaces, e.g.
<code>
class-map type inspect match-any pass_cmap_in
match access-group name pass-ipv4-in
!
class-map type inspect match-any ph_cmap_in
match access-group name ph-ipv4-in
[code]....
There is some basic stuff in the Access-Lists; direction ph-ipv4-in contains basically "permit ip any any" and ph-ipv4-out contains some permits for certain services, but nothing else. The pass-ipv4-in/out ACL contains particularly the udp-500/4500-stuff as well as gre/esp/ah.
Here are the zone-pairs:
<code>
zone-pair security zone_ph-zone_outside source zone_ph destination zone_outside
service-policy type inspect ph_pmap_in
!
zone-pair security zone_outside-zone_ph source zone_outside destination zone_ph
service-policy type inspect ph_pmap_out
!
</code>
[code]...
The xconnect is only built up correctly when I configure the interface in the zone_outside. The destination for the xconnect is an ASR9k. If I do not configure the zone on the L2VPN-Interface, only arp-packet are allowed to tgo through the tunnel.
The L2VPN connects a branch office to the network of "PH". Now the trouble starts: when they are putting a host in the branch office, DHCP via the L2VPn works fine, they can ping anything from the branch office-PC in their local network and reach all internal servers etc.
BUT if they want to go to a destination outside their network, it will not work properly. For example, the branch-office-PC can ping 8.8.8.8 fine, but when they try to connect to a website, e.g. www.google.com, they run into a timeout. Netstat says, that the http-syn is sent, but no ack is received.
On the router, I see:
Session 1178BAE8 (x.y.225.250:2370)=>(173.194.35.151:80) http SIS_OPENING
whereas x.y.225.250 is the PC connected via L2VPN in the branch office to their local lan. When they put the same machine in their local lan directly behind the router (without l2vpn) everything works fine. When I switch off the firewall on the Gi0/0/0-Interface, the PC from the branch office also reaches its destination, so for me it looks like the firewall inspects the traffic going via Gi0/0/1 and L2VPN, what in my opinion, it should not do....
