Can't apply policy route-map on C3750 stack vlan interface
Hi All.
I've come up with this problem and i could see some people have had the same issue. I've tried to overlook and check other replies but it didn't help me. So I'm hoping someone could spot the problem. Here are the details:

There are 2 ISPs, G1/0/1 and G2/0/1. After creating a route-map i can apply a policy route-map to Vlan5 and it accepts without any errors. But when you do sh run vlan5 the command is not there, it's not applied.
Any help will be appretiated.
Thanks.
Hi Jon.
Thanks for your reply. I didn't put those configs as they're basic without use of VRF and WCCP. Also i've checked or tried to find the list of unsupported commands and didn't see them in that list. See config below with some extras:

I've tried to apply both policies pbr1 and pbr2, it allowed to do that without errors but at the end it wasn't there.

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 Policy Routing be configured on the RPR interface?
We have three 10720 routers connected via RPR ring. And we found the policy routing is not working, however the same config works on Ethernet interfaces.
Are you applying the config on the DPT interface or the Ethernet interface? I'd be suprised if you could configure any policy routing on the DPT interface. Rather I would have thought it should be applied on the Ethernet interfaces involved in the connection. Bear in mind that the router function of the 10720 does not really see the DPT ring, but as logical point to point links.

Route-Map not taken on 3850 IP Services
Something odd I am seeing.
Trying to use a 3850 L3 switch running IP Services, XE ver 03.03.03SE, to do some policy routing on one of the VLAN interfaces.
Interface VLAN 10
ip address 208.x.y.z 255.255.255.0
ip policy route-map Use_Route1
It seems to take the command but when I look back with a show run interface vlan 10, it is not there.
Also when I look at the show route policy it indicates that 0 packets have been processed.
Is this a bug or am I missing something?Hi Richard,
Cisco 3850 even running on full IP services image will not support verify-availability command to track with IP SLA.
If you enable terminal monitor or configure the device using console you can see the syslog message when you try to configure the route-map with set ip next-hop verify-availability command
%PLATFORM_PBR-3-UNSUPPORTED_RMAP: Route-map <name> not supported for Policy-Based Routing
You can see the route-map command showing up in the config BUT as soon as you try to apply to interface vlan10 the command will be not be applied and PBR will not work.
I hope Cisco find way to fix this!!
Workaround:
You can use EEM Applet with IP SLA
event manager applet internet_up
event syslog pattern "%TRACKING-5-STATE: 1 ip sla 1 reachability Down->Up"
action 2.0 cli command "enable"
action 3.0 cli command "config t"
action 3.2 cli command "interface Vlan10"
action 3.3 cli command "ip policy router-map Use_Internet"
action 3.4 cli command "exit"
event manager applet internet_down
event syslog pattern "%TRACKING-5-STATE: 1 ip sla 1 reachability Up->Down"
action 2.0 cli command "enable"
action 3.0 cli command "config t"
action 3.2 cli command "interface Vlan10"
action 3.3 cli command "no ip policy router-map Use_Internet"
action 3.4 cli command "exit"
repeat the same process for other IP SLA tracking you have
hope this helps

Route Map Policy on SVI - Trunk from ESX
Hi,
I have a question regarding the following configuration.
A route map matches traffic from a particular subnet, say on VLAN 10 (using an ACL).
A route map policy is applied on this SVI (int vlan 10)
A server on this subnet is running on ESX which is connected to the switch on a trunk port.
The ESX host tags all frames from this server as VLAN 10.
In this scenario, should the route map pick up the traffic from this server? I don't see why not, but in my testing it doesn't seem to be working :)
Thanks for any help.Hi Alex,
It's a 3750x (stack) with 12.2(55)SE5.
I've already changed the SDM template to routing and rebooted the switch.
I don't think the route map is working at all actually :) See config below, let me know if you can spot anything obvious but the networks on the ACL are definitely correct.
Thanks again.

Applying "route-map" in interfaces with encapsulation dot1q
Hello,
I would like to ask you if there were some trouble in applying route-maps in a interface and its subinterfaces, as it is shown:
interface GigabitEthernet0/2
ip address 11.0.9.26 255.255.255.252
ip policy route-map GestionRadios
interface GigabitEthernet0/2.11
encapsulation dot1Q 11
ip address 11.0.9.18 255.255.255.252
ip policy route-map RedOperativaA
interface GigabitEthernet0/2.12
encapsulation dot1Q 12
ip address 11.0.9.22 255.255.255.252
ip policy route-map RedOperativaB
I am not sure if it is correct totally. Besides I get this informacion doing "show ip policy" and it seems to be right.
Router#show ip policy
Interface Route map
Gi0/2 GestionRadios
Gi0/2.11 RedOperativaA
Gi0/2.12 RedOperativaB
I would be very grateful for your help.
Thanks in advance

We do not have much to work with in your post so giving you really good answers is difficult. You do not tell us what type of device this is (I assume probably a router, but perhaps it is a layer 3 switch?) or what version of code it is running. These things make a difference sometimes in what is supported or is not supported. But since you get output in show ip policy then I assume that the device does support configuration of this feature.
You show us the configuration of the interfaces but not the configuration of the route maps or the access lists which the route maps probably use. So we can not form an opinion of the validity of the route maps or the access lists.
And you do not tell us whether the Policy Based Routing is working or not (and in fact you do not tell us for sure that you are doing PBR - though that is generally what route maps on the interfaces are doing) so we are not clear whether there is a problem here or not.
But based on what you show us in this post I do not see any particular problems with the route maps and the way that you have applied them to interfaces (assuming that your goal is really to do PBR).

Policy based routing to host in same vlan/subnet
Hello i have nexus 7k that i have a policy based routing setup as follows for 2 vlans, 802 and 803, to set default route out to a host in vlan 802. i have applied my policy to the vlans and everything works fine for a host in vlan 803, it routes over and out properly. However when im in vlan 802 my host traffic never gets to 172.21.1.237 when pointed at the gateway 172.21.1.1. I can see the pbr statistics incrementing indicating that i am initially hitting the policy but im not sure where my traffic goes after that. I can talk to .237 direct in the vlan but i would like this to work through pbr to utilize all of my other routes and default gateway.
vlans 802
172.21.1.1/24
ip policy route-map West
vlan 803
172.21.17.1/24
ip policy route-map West
route-map West permit 10
match vlan 802-803
set ip default next-hop 172.21.1.237
Im thinking there is some kind of hairpinning problem or maybe im creating some kind of blackhole.
any help is appreciated.
thanks, scottScott
If the destination IP is in the same subnet as source IP then it won't be routed it will be L2 switched so it would never use the default gateway ie.
src IP 172.21.1.10 255.255.255.0
dst IP 172.21.1.237 255.255.255.0
src compares it's own IP with it's subnet mask and sees it is on the 172.21.1.x network. src then compares the destination IP with it's own subnet mask and sees it is also on the 172.21.1.x network so it simply arps out for that address and when it gets the mac address it sends it direct to the destination. It would only use the default gateway if the destination IP was on a different network.
So i don't see how you will be able to do this and i'm not sure why you are seeing hits in your PBR acl for the host in the 172.21.1.x network.
Edit - what exactly do you mean when you say -
However when im in vlan 802 my host traffic never gets to 172.21.1.237 when pointed at the gateway 172.21.1.1.
How are you doing this ie. pointing it to the default gateway because as i say it should always be able to communicate with 172.21.1.237 as it is in the same subnet.

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 are the access-list and route-maps:

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). -
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.?

Policy routing via address ranges
Is it possible to use policy routing based on ranges of a subnet? I want to have 192.168.1.1-100 go out e0 and 192.168.1.101-250 go out e1. From what I've read it only looks like policy routing works with route-maps using access lists
You certainly can.. just use multiple lines in your ACLs to cover each range.
For example,
192.168.1.1-100 can be covered by:
access-list 1 permit 192.168.1.0 0.0.0.63
access-list 1 permit 192.168.1.64 0.0.0.31
access-list 1 permit 192.168.1.96 0.0.0.3
access-list 1 permit 192.168.1.100 0.0.0.0
And use the following for everything else:
access-list 1 permit 192.168.1.0 0.0.0.255
So you can use the following:
route-map PBR permit 10
match ip address 1
set interface e0
route-map PBR permit 20
match ip address 2
set interface e1
Hope that helps - pls rate the post if it does.

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

IOS used: c3550-i5q3l2-mz.121-22.EA3.bin
I try to policy-route packets coming from a certain source (160.160.160.0/24)to a next-hop ip address:
route-map from_server permit 10
match ip address 160
set ip next-hop 192.168.1.1
access-list 160 permit ip 160.160.160.0 0.0.0.255 any
interface GigabitEthernet0/1
ip policy route-map from_server
The next-hop IP is in the routing table, nevertheless the packets matched with ACL 160 are not policy-routed.
What am I doing wrong? Any ideas?
Thanks a lot
FlorianYou probably need to do this to get PBR to work:
You must modify the SDM template to enable the switch to support the 144-bit Layer 3 TCAM. Use
the sdm prefer extended-match, sdm prefer access extended-match, or the sdm prefer routing
extended-match global configuration commands to reformat the TCAM space allocated to unicast
routing in the default, access, or routing template, respectively. Reformatting the unicast routing
TCAM reduces by half the number of supported unicast routes in the template.
This is from the configuration guide for the 3550.
