ASA 5585-X Route-Map
Hi,
how can apply route-map rules to an interface ?
i set up some rules but i cannot apply these rules any interface.
Thanks a lot.
Thank you Kanwal.
in a cisco router you can apply your route-map by using command ip policy map ... İ didnt find any command like this. İ set up some match and set conditions but i do not apply any interface.
can i use route-map to manipulate routing table İn asa 5585-x.?
sincerely

Which routing protocols are supported on ASA 5585
Hi,
I am curious to know which routing protocol is well supported on Cisco ASA 5585. do someone on the forum has implemented routing on ASA?
I have ASA 5585 on context mode, as of now 4 contexts have been created. upstream device is Nexus.
I have ASA with Software Version 8.4(4)1 and Device Manager Version 6.4(9).
if someone can point me to good implemented example of routing protocol to their environment (like OSPF, BGP) that would be great.
ThanksYou're welcome.
Multiple contexts adds another twist - in ASA 8.4 dynamic routing protocols are not supported at all for multiple contexts. Reference.
ASA 9.0 added support for dynamic routing protocols in multiple context modes, including OSPF v2 (but not v3 for IPv6). Reference.
FYI ASA 9.1(2) is current as of this writing and is the recommended release in the 9.x train. (Mentioned near the end of the latest TAC Security podcast - episode #37 here.) -
Hi,
Is there any way to create vlans on cisco asa 5585 similar way we do for cisco switches.
The asa in this case is an interface for subsidary users to connect into this new network.
We require few vlans to be created for some servers on the firewall. the firewall should be the gateway for these servers.
eg. vlan 100 - 192.168.100.1/24 should be on the ASA firewall.
How do we achieve this?
Appreciate all help on this.Hi,
You will have to configure atleast one physical interface as a Trunk interface if you want to bring the Vlan all the way to the ASA. Essentially the configuration follows the same lines as configuring a Cisco router to act as the gateway for multiple Vlans behind a switch.
The actual configuration format depends on how you have set up the ASA. Is it Single Context or Multiple Context?
In Single Context the configuration would be something like this
interface GigabitEthernet0/0
description TRUNK
interface GigabitEthernet0/0.100
vlan 100
nameif LAN
security-level 100
ip add 10.10.10.1 255.255.255.0
interface GigabitEthernet0/0.200
vlan 200
nameif DMZ
security-level 50
ip add 192.168.10.1 255.255.255.0
If you are running Multiple Context mode the configuration could be something like this
interface GigabitEthernet0/0
description TRUNK
interface GigabitEthernet0/0.100
description LAN
vlan 100
interface GigabitEthernet0/0.200
description DMZ
vlan 200
context EXAMPLE-CONTEXT
allocate-interface GigabitEthernet0/0.100
allocate-interface GigabitEthernet0/0.200
config-url disk0:/EXAMPLE-CONTEXT.cfg
Or something along these lines
Hope this helps

Route-map after tunnel end point
Hello Folks. I have an ASA5510 with multiple tunnels terminating into it. Some sites require a hairpin bend out into the internet after terminating, this works fine with an applicable NAT statement, however, is it possible to use a route-map to route this traffic that would normally hair pin bend out the same interface back into the internet, but rather go out through another link on another host?
yes, you can
but not with route map because in ASA there is not route map
so u need first put the folowing command to allow the tunnel exit from the same interface where it is terminated orginally
issue the
same-security-traffic intra-interface
command in the global configuration mode
and for more configurations details use the following link will be useful for your case

Hi All,
I'm trying to achieve the following -
I have a host 10.44.125.70.
If going to any Internal address space I want the host to use a certain next hop (vlan interface on core this PBR is configured). Then IF going to anywhere else (e.g external address) , use a different next hop. I have the below but doesn't seem to be working as expected. Is my first route-map entry catching all traffic? I'm sure what I'm trying to do is very simple...
IP access list Sent_Inside
10 permit ip host 10.44.125.70 172.12.0.0 0.0.15.255
30 permit ip host 10.44.125.70 10.0.0.0 0.255.255.255
IP access list Sent_Outside
10 permit ip host 10.44.125.70 any
20 permit ip host 10.44.125.70 any
route-map TEST permit 20
match ip address Sent_Inside
set ip next-hop 10.44.125.1
route-map TEST permit 30
match ip address Sent_Outside
set ip next-hop 10.44.141.7Exactly John, a different default route already exists. Because I have a static NAT on the ASA (10.44.141.7) for this host of mine, I need to make sure all Internet traffic uses the ASA and not the default route on the Core.
What is happening at the moment is - If I have just the below.Then the device 10.44.125.70 is accessible from the Outside on my Nat'd external address (ASA config is all good and setup with NAT etc..). I then realised I could not access my hosts internal IP within the network so i added the extra parts to my route-map. Upon doing this my NAT stopped working (but I could then access my internal address internally). Not going to be able to test this again until tomorrow either which isn't ideal.
IP access list Sent_Outside
10 permit ip host 10.44.125.70 any
20 permit ip host 10.44.125.70 any
route-map TEST permit 30
match ip address Sent_Outside
set ip next-hop 10.44.141.7 -
IPSec ikev2 between ASA and Cisco Router
Hi,
i try to do IPSec with ikev2 (SHA2) between ASA and Cisco Router, without success. Any one can help me ?
- Remote site (Router) with dynamic public IP -> Dynamic crypto map on the ASA
- Authentication with Certificats
- integrity sha2
I try a lot of configurations without success.
Thanks for your help.
MicThe more secure ike policy should have the higher priority which is a smaller number. So I would configure there the following way (policy 30 only if really needed):
crypto ikev1 policy 10
authentication pre-share
encryption aes-256
hash sha
group 5
lifetime 28800
crypto ikev1 policy 20
authentication pre-share
encryption aes-256
hash sha
group 2
lifetime 28800
crypto ikev1 policy 30
authentication pre-share
encryption aes
hash sha
group 2
lifetime 43200
The Cisco VPN Client is EOL and not supported any longer. And yes, by default DH group 2 is used. But that can be configured by a parameter in the PCF-file.
There are two (three) better options:
Best option with very little needed configuration:
Move to AnyConnect with TLS. AnyConnect is the actual Cisco client that is also supported with Windows 8.x. The legacy IPsec client isn't.
Best option with a little stronger crypto but more configuration:
Move to AnyConnect with IPsec/IKEv2.
Move to a third-party client like shrew.net. I didn't use that client since a couple of years any more, but it's quite flexible and also has a config for a better DH-group.
For option 1) and 2) there is an extra license needed, but thats not very expensive. -
I want to create a port-channel with 2 10Gbs interfaces on 2 ASA 5585 firewalls, and set them up in a failover pair.
In order to do this, do I simply put two 10Gbs interfaces into a channel and then configure the IP addressing and failover address on the logical port-channel interface? (aka interface po1).
Any limitations with this?Yes, that is exactly what you do..
Create portchannel on switch and ASA
Trunk the vlan on switch side
Create logical interfaces on ASA -
Managing Route-Map based MPLS VPN
1) How to derive the VPN information of the MPLS VPN configured using route-maps? As I understand, stitching route-maps information to derive VPN is complex as it is difficult to derive & correlate the filters tied to each of the route-maps that are tied to a VRF :(
2) Is there any MIB to get from the MIB
a) Route-maps tied to each VRF
b) What is the filter associated with each route-map?
c) Definition of each of the above filter
It would have been nice if the route-maps' name had global-significance within AS, so that we could have treated route-maps, pretty much like the route-tragets. Alas, I doubt it is :(
It should be noted here that if the MPLS VPN is configured using route targets, the VPN information derivation is fairly straight forward throught MplsVpn MIB.
So, the question is what is the simplest way to derive the MPLS VPN info given that they are configured using route-maps in BGP for labelled-route-distribution & for the pkt association with the VRFs.
Thanks,
Suresh REach CE in a customer VPN is also added to the management VPN by selecting the Join the management VPN option in the service request user interface.
The function of the management route map is to allow only the routes to the specific CE into the management VPN. The Cisco IOS supports only one export route map and one import route map per VRF.

BGP Outbound Route-Map Question
Hi Experts,
Just need your help again. I was trying to do some lab and I came across this weird behaviour with BGP outbound route-map. The diagram is simple.
Please see attached diagram. Sorry for the very poor illustration. R6 has iBGP peering to both R4 and R1. Both R1 and R4 have eBGP peering to R5. No IGP running on any routers as well to keep things simple. There are 2 things to do.
* Create a static route for 160.1.0.0/16 pointing to Null0 on both R1 and R4 and advertise to BGP via network statement but only R5 should be able to see the 160.1.0.0/16 route. R6 should not receive it.
* Advertise R5's /32 loopback interface to BGP but ensure R6 to have that route in its routing table. Don't use next-hop-self on both R1 and R4. Don't advertise WAN link via network command.
I'll just illustrate R4 and R6 here to keep things straight forward.
R4#sh ip bgp
BGP table version is 5, local router ID is 150.1.4.4
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
*> 150.1.5.5/32 155.1.45.5 0 0 100 i
*> 160.1.0.0 0.0.0.0 0 32768 i
R6#sh ip bgp
BGP table version is 11, local router ID is 150.1.6.6
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
* i150.1.5.5/32 155.1.45.5 0 100 0 100 i
* i 155.1.0.5 0 100 0 100 i
The first task was achieved as the 160.0.0.0/16 route is not present in R6's table. I used these commands in R4.
router bgp 65000
no synchronization
bgp log-neighbor-changes
network 160.1.0.0
neighbor 155.1.45.5 remote-as 100
neighbor 155.1.146.6 remote-as 65000
neighbor 155.1.146.6 route-map R6_OUT out
no auto-summary
route-map R6_OUT deny 5
match ip address prefix-list AGGR
route-map R6_OUT permit 1000
ip prefix-list AGGR seq 5 permit 160.1.0.0/16
So with the configuration above, it is clear that R4 is hitting route-map line 5 to deny 160.1.0.0/16 being advertised to R6. I tried to remove line 5 to validate as well if the /16 route will be advertised to R6 and it did so route-map configuration above is confirmed working.
Next, advertise loopback 0 of R5 to R6 and make sure it is a valid route in BGP table without the use of next-hop-self or WAN advertisement.
I used the following configuration.
ip prefix-list R5_LINK seq 5 permit 155.1.45.5/32
route-map R6_OUT permit 10
match ip route-source R5_LINK
set ip next-hop 155.1.146.4
I inserted line 10 in between route-map 5 and 1000. So R4 would check its route table for routes with 155.1.45.5 as route-source then advertise it to R6 with next-hop address of 155.1.146.4. It worked!
R6#sh ip bgp
BGP table version is 15, local router ID is 150.1.6.6
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale

Network Next Hop Metric LocPrf Weight Path
*>i150.1.5.5/32 155.1.146.4 0 100 0 100 i
* i 155.1.0.5 0 100 0 100 i
*>i160.1.0.0 155.1.146.4 0 100 0 i
As you can see above, 150.1.5.5 route is now a valid BGP route but surprisingly, the 160.1.0.0/16 route is there! From what I have seen, BGP skipped line 5 and started at 10. Even if I insert the same rule as line 5 and make it as line 15, it's not working. The /16 route is still being advertised. If I remove the match ip route-source clause in sequence 10 then it will withdraw the 160.1.0.0/16 route again. Looks like "match ip route-source" is not very friendly with direct filtering to BGP neighbors but I saw this being used with BGP inject-map and it worked well.
R4#sh route-map
route-map R6_OUT, deny, sequence 5

Any thoughts why this is happening?
Thanks in advance.Hi John,
I did a small lab to test feature "match ip route-source" and it is working fine. Please check below config and output.
R4 does not have 172.16.16.0/24 and also routes for which next-hop is not 1.1.1.1. In case you still facing issue, please share output of "debug ip bgp updates out"

thanksDefault PBR:
All packets received on an interface (ingress) with PBR enabled are entertained, first they should match through ACL then forward to next hop. if a match is exist (through ACL) but not forward to next hop then do nothing this packet especially for ICMP packet.
I think you need Local PBR:
Packets that are generated by the router are not normally policy-routed. To enable local PBR for such packets, indicate which route map the router should use by using the following command in global configuration mode:
ip local policy route-map TEST

I have a 6509 that I've setup with route-maps in order to route VLANs in different ways. For example, if we wanted some vlans to get out to the internet we would route them to a certain address. Then there is another vlan that we route to another internet gateway. It was all working pretty good until we swapped out another switch gateway in the network and every since things have been wonky. It seems as though the switch is routing packets that would normally stay on that switch out of the switch then back in, even though my access-list are set to deny the traffic.

Here is how we tested the system and found the error. We cut the connection to 192.168.4.1 router, and when we try to ping a host on the 100 VLAN with the ip address of 192.168.24.101 from the MISC vlan with a ip address of 172.168.11.9 the ping just fails. When we enable the connection to the 192.168.4.1 router the pings go through again. What in my route-map is causing this, I thought I setup the deny rules pretty good?Hi Mike,
Between you and me, this is a lengthy config you have there.
Next don't forget that a route-map doesn't apply to traffic originated or destined to the self-device, unless you use ip local policy in which might work, but there I have seen some nasty bugs.
So if you can shorten your config to one example, then do the tests :
- sourced from device A (it can be the SVI of another switch)
- through your 6509
- destined to device B (it also can be the SVI of another switch, or even simpler some loopback inteface). -
What is the second, third, etc. next-hop address in the route-map set command for?
route-map TEST_PBR permit 10 match
match ip address 101
router(config-route-map)#set ip next-hop 1.1.1.1 ?
A.B.C.D IP address of next hopHi,
You may get your answer in below link
http://www.groupstudy.com/archives/ccielab/200812/msg00999.html
First next-hop will be used unless until that is not unreachable. If first is unreachable, then next one will be used. Since these next-hops are directly connected, router can easily come to know whether they are active or not. In case you want to set some loopback ip as next-hop then you need to use keyword recursive "set ip next-hop recursive"

Local policy route-map for policy route
Hi
this is related my previous question:
I want to set policy route on asr1004, that redirect vpn traffic.
my case is:
asr1004 import a default route 0.0.0.0 from int 0 with bgp neibour address 10.100.100.100
assume internal traffic 10.10.10.0/24 coming into asr1004 on int 1.
assume vpn with ip address 10.2.2.2 is direct linked to asr1004 int 2, and int 2 ip address is 10.2.2.1
assume taget network is 10.200.200.0/24
I want internal traffic (10.10.10.0/24) go to target (10.200.200.0/24) to be redirect to10.2.2.2 (vpn) first, so I add "ip route 10.200.200.0/24 10.2.2.2" on asr1004.
Than, I want vpn (10.2.2.2) encrypt traffic and send it to one of ip in10.200.200.0/24 range again. at this point if I put local policy route-map below, is it will work?
ip local policy route-map vpn-out
access-list 100 permit ip 10.2.2.2 any
route-map vpn-out permit 10
match ip address 100
set ip next-hop 10.100.100.100
if not, do I have any change to do policy route for this case?
any comment will be appreciated
Thanks in advance

can I refresh the question again:

assume internal traffic 10.10.0.0/16 coming into asr1004 on int 1 with ip address 10.3.3.3
assume vpn with ip address 10.10.2.2 is direct linked to asr1004 int 2, and int 2 ip address is 10.10.2.1
assume taget network is 10.200.200.0/24

Cisco 4900m, pbr, route-map
Hi,
My customer has a question, what is the limit for entries for the route-map for PBR that will be done in hardware? This applies to soft-4900M 12.2 (53) SG2. I need a reference to documentation.
Regards,
lbHi Lukasz,
the 4900M is a Data Center Switch and not a Metro one, so it is more appropriate if you post these types of questions on Network Infrastructure > LAN Switching and Routing section
(the 4900M should not be confused with the ME4900 series, which are Metro switches instead).
Anyway it supports 128.000 Security and Quality-of-Service (QoS) Hardware Entries as documented here:
http://www.cisco.com/en/US/products/ps6021/prod_models_comparison.html
and here:

Hi All,
I have just taken over supporting a network, and have come accross a route map, that I don't really understand. The route-map is copied below. Can anyone please tell me step by step how its processed, and what the outcome is?
route-map test permit 5
match ip address prefix-list path_one_prefer
route-map test permit 10
match as-path 3
route-map test permit 20
match ip address prefix-list route-filter
set as-path prepend 65100
ip prefix-list path_one_prefer seq 5 permit 10.10.0.0/16
ip as-path access-list 3 permit _65000_
ip prefix-list route-filter seq 10 deny 172.130.1.0/28
ip prefix-list route-filter seq 15 deny 172.131.1.248/29
ip prefix-list route-filter seq 20 deny 172.200.128.0/27
The route map is applied outbound towards an ebgp peer
Many Thanks
RussHello Russ,
Yes that is indeed the case.
route-map test permit 20
match ip address prefix-list route-filter
set as-path prepend 65100
!ip prefix-list route-filter seq 10 deny 172.130.1.0/28
ip prefix-list route-filter seq 15 deny 172.131.1.248/29
ip prefix-list route-filter seq 20 deny 172.200.128.0/27
In the route-map lines 20 - it is set to "match ip address prefix-list route-filter"
Since the deny is in place in the prefix list, take it as "Not these ones"
Everything else is permitted and AS-Path prepended.
After line 20 there is no other - ACL logic - explicit deny - so if there is no match, its a deny, so the prefix's in the prefix-list "route-filter" are not advertised.
This line 20 seems to be the "catch all" other routes except for these ones i.e. that prefix list, and prepend them.
Check the routes you are advertising them as I stated in my first post with "show ip bgp neigh x.x.x.x advertised-routes" which should correlate with the route-map applied to your BGP peer.
Hope this makes it clear.
