Route map policy on Catalyst4500x
Does anyone know about route map policy on Catalyst4500x ? Is it do on hardware or software ? I try to use policy route map to match and redirect traffic about 1 Gbps
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.

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 :)

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

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:

Hi all,
may some of you tell me the real meaning of the sub-command "set interface <intf>" under the route-map section?
I thought it was like the <intf> parameter whe you set a route out of an interface.
I tried it with a PIX that should have to act as proxy-arp device but nothing happened.
Everything worked fine using "set ip next-hop ..."
The topology appears a little bit complicated if explained how I built it in practice.
Just a PIX525, a switch and a router 877 that manages VLANS.
I reproduced the environment that doesn't see 2 ethernet interfaces on the router where the policy is applied but 1 serial and 1 ethernet. By now there are 2 devices, one per link, and the def route is based on proxy-arp both for the serial and the ethernet.
Hope the scenario was clearly depicted.
TIA

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
Origin codes: i - IGP, e - EGP, ? - incomplete
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
Match clauses:
ip address prefix-lists: AGGR
Set clauses:
Policy routing matches: 0 packets, 0 bytes
route-map R6_OUT, permit, sequence 10

Policy routing matches: 0 packets, 0 bytes
route-map R6_OUT, permit, sequence 1000
Match clauses:

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 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.?
sincerely -
Can anyone tell me what a route map is and how they work, thanks
Carlhi
route maps are used for different purposes like policy based routing,controlling the routing updates also for number of administrative functionalities.
But the usage of route maps can be found mostly inline with PBR where the forwarding is being done based on different criterias.
Abstracts from CCO
"They are an ordered sequence of individual statements, each has a permit or deny result. Evaluation of ACL or route-maps consists of a list scan, in a predetermined order, and an evaluation of the criteria of each statement that matches. A list scan is aborted once the first statement match is found and an action associated with the statement match is performed".
"They are generic mechanismscriteria matches and match interpretation are dictated by the way they are applied. The same route-map applied to different tasks might be interpreted differently".

Do you mean this -
route-map Internet_side_map permit 10
match ip address Internet_side1
set ip next-hop 1.1.1.2
route-map Internet_side_map permit 20
match ip address Internet_side2
set ip next-hop 2.2.2.2
the above will -
1) if the packet matches the first permit statement it will be sent to 1.1.1.2. If there is no match then -
2) if the packet matches the second permit it will be sent to 2.2.2.2. If there is no match then -
3) the packet will be routed using the routing table.
That is how it will work. I don't know whether this will do what you want though without knowing how your network is setup.

Route Map - Delete Sequence Number
Hi All,
Taking the cisco example below, which demos how to PBR.
access-list 1 permit 209.165.200.225
access-list 2 permit 209.165.200.226
interface ethernet 1
ip policy route-map Texas
route-map Texas permit 10
match ip address 1
set ip precedence priority
set ip next-hop 209.165.200.227
route-map Texas permit 20
match ip address 2
set ip precedence critical
set ip next-hop 209.165.200.228
How would i safely remove sequence number 20 from the above?
Many thanks.Hi John,
no route-map Texas 20 worked good.

Route-map continue, in CRS RPL
Dear all,
what is the replacement for continue command in route-map for CRS IOS XR RPL ?
is it ? pass command ??
actually i had some issue matching almost 15 community attribute ingress from customer network...
and i think, is it can be done with pass command ?
like :
if community (a:a) then
action
pass
else if community (b:b) then
action
pass
end if
so, when the route contain community a:a, will get action assigned, and not yet to be forwarded, instead, will continue to run the next if, to check if the route also contain b:b community...
so with this i dont have to create almost 2^15 combination if format on RPL.
is it do able ? or is there any command that work simillar with "continue" command in route-map, if match, the route still get processed until the end of policy.
Thanks a lot,
Budi LHello Budi
Yes, the pass statement allows a policy to continue executing even though the route has not been modified. When a policy has finished executing, any route that has been modified in the policy or any route that has received a pass disposition in the policy, successfully passes the policy and completes the execution. Note, a policy does not modify route attribute values until all tests have been completed. In other words, comparison operators always run on the initial data in the route. Intermediate modifications of the route attributes do not have a cascading effect on the evaluation of the policy.
Here is the PASS example:
route-policy ak-community
if community matches-any (11:11, 44:44) then
set community (55:55) additive
pass
endif
if community matches-any (22:22) then
set community (77:77) additive
endif
end-policy
If a route contains a community 11:11 then we add 55:55 and continue. So If the same route contain 22:22 as well, we’d add another community 77:77 to the same route. Note, if we have an action (like SET here), a PASS statement is not needed and we continue with the policy.
Example 2. Here we can see nested IF. So if a route contains 11:11 then we add 55:55 and verify it further if the route has 22:22 and if so, add 77:77
route-policy ak-community
if community matches-any (11:11, 44:44) then
set community (55:55) additive
if community matches-any (22:22) then
set community (77:77) additive
endif
endif
end-policy
Example 3. In this example we add 55:55 to routes matching 11:11 or 44:44. Otherwise, if a route has 22:22, we add 77:77. Note, if a route has 11:11 AND 22:22 (or 44:44 AND 22:22) we’d add 55:55 only.
route-policy ak-community
if community matches-any (11:11, 44:44) then
set community (55:55) additive
elseif community matches-any (22:22) then
set community (77:77) additive
endif
end-policy
IF statement are flexible too. You noted we used MATCHES-ANY in the IF statement. We can use a list of different conations in one IF. For example:
If community matches-every (11:11, 22:22) or destination in (11.1.3.0/24) then
set local-preference 500

please if i configure route-map for two access list like below '
interface tengig 1
ip policy route-map ABC
access-list 101 permit any eq www 1.1.1.0 0.0.0.255
access-list 102 permit any eq www 2.2.2.0 0.0.0.255
route-map ABC permit 10
match ip add 101
set ip next-hop 50.1.1.1
route-map ABC permit 20
match ip add 102
set ip next-hop 60.1.1.1
is it need to write this string below ?
route-map ABC permit 30
set default interface null0Rawa
If you do that any packets that don't match acl 101 or acl 102 and there is no explicit route in the routing table they will be routed to null0. So it depends on whether you want that or not.
I explained this before in that if a packet does not match any PBR route map statements then those packets will be routed using the routing table. However in your example in the last statement, because you have not specified a match statement, all packets that didn't match the acls or have an explicit route in the routing table will be routed to null0.
