Cisco Switching/Routing :: Policy Based Routing Not Done In Hardware With 7604-S

Mar 11, 2012

I am having a problem with PBR done on a 7604-S router - It seems like it is not done in harware. I have an Iperf client and an Iperf server, and would like to test the performance of 7600 router for PBR, supervisor is RSP720-3C-G and used interface card is 7600-ES20-GE3C ESM20G.

I have read  numerous discussions about PBR that is supposed to happen in hardware when you use it with matching access-list and set ip next-hop.Although, when I start the iperf, the 7600 cpu is hitting the 80-90 % boundary, and transfer bandwidth can't go over 120-130 Mbit/s.The IP Policy is applied on an interface part of vrf ONE maybe this is casing the problem... ?

The diagram and configuration follows:
Configuration:
 
c7604#sh run

Cisco Switching/Routing :: Policy Routing Based On Client Gateway (6509-E)

Feb 26, 2012

If client gateway = 192.168.64.9 then next-hop = 192.168.64.8 else use default-route 0.0.0.0
 
I know it's possible to do a route-map match ip-address ACL list. But is it possible to match on gateway?
 
Some info about hardware and config:

6509-E in VSS (IOS 12.2(17r)SX5) withVS-S720-10G supervisor.

All routes are static, IP for 192.168.64.9 is on SVI vlan.

Cisco Switching/Routing :: Policy Based Routing With 3750 Switches

Oct 17, 2011

I have a simple design with 3750. I configured a route-map which define a next hop. I defined this route-map on a policy on a vlan interface.When I test some ping and a debug ip policy and it seems that my policy never match.Is there any mechanism that prevent the switch from using PBR? I think of CEF .

Cisco Switching/Routing :: How To Configure Policy Based Routing On 3750

Jan 28, 2013

In our datacenter we have a 3750 stack with IP base image.  I have enabled PBR and reloaded the switch.  Show sdm prefer says i am using default template.  The reason i want to use PBR is that we have 2 firewalls on the same work and want to be able to have granular control over which gateway out of the network they use but still be able to access all internal resouces accross wan and locally.

Created access list to identify traffic:
 
access-list 10 permit 10.2.3.59 (test workstation on vlan 3)
 
Created policy:
 
route-map TestASA permit 10
match ip address 10
set ip next-hop 10.2.0.3
 
Assigned policy to the user vlan3:
 
ip policy route-map TestASA
 
Results:It changed the default gateway to the above gateway but i could not access any resources on any other vlan, could not access resouces accross wan.

Cisco Switching/Routing :: Make Policy Based Routing On 3560?

Apr 17, 2012

I have tried to make policy based routing on Cisco 3560. I use ipservices ios (SW version 12.2.(50)SE3 and SW-IMAGE C3560-IPSERVICESK9-M)  For below configuration there is no problem and pbr is working.
 
“Access-list 100 permit ip host  1.1.1.1 host 2.2.2.2
Access-list 101 permit ip host  1.1.1.1 host 3.3.3.3
 Route-map pbr1  permit 10
Match ip address  100
Set ip next-hop verify-availability  1.1.1.2 1 track 11
 interface fasthethernet  0/1
ip policy route-map  pbr1”
 
But when i add another sequence to the "pbr1" with another sequence number  like that.
 
“Route-map pbr1 permit  11
Match ip address  101
Set ip next-hop verify-availability  1.1.1.3 1 track 12”
 
pbr is not working. Switch gives message "PLATFORM_PBR-3-UNSUPPORTTED_RMP:Route-map pbr1 not supported for Policy Based  Routing”"ip policy route-map pbr1" command not shown in the running config. And "show ip policy" output is blank.Configuration guide says you have insert many sequence to the route-map with the same name. And also this command is not in the unsupported command list.

Cisco Switching/Routing :: 1900 - Clear DF Bit And Policy Based Routing

Jan 8, 2012

I've been implementing a setup where a remote office has a Cisco 1900 router. There are 2 GRE/ IP SEC tunnels to the headquarters, 1 over public internet, 1 over a private cloud. Because of some MTU issues we have to clear the DF bit for some of the traffic, but we also want to use PBR to send https traffic over the "public internet" tunnel and the rest of the traffic over the "private cloud" tunnel. I'm able to clear the DF bit and to do the PBR with route-maps, but I'm not able to implement both functionality at the same time.

Cisco Switching/Routing :: 7200 - QoS Input Policy Doesn't Classify ICMP Packet Based On DSCP

Dec 20, 2011

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.

Cisco WAN :: 3560 / Policy Based Routing With InterVLan Routing

Jan 14, 2011

I have 3560 with attached 3 networks, 172.16.1.0/24 172.16.2.0/24 and 172.16.4.0/24, all of them have a vlan interface, 172.16.1.254, 172.16.2.254, and 172.16.4.254, I have enabled intervlan routing with command ip routing and they have route beetwen each other. Now I want to create PBR and let them go to the internet from different gateways.

so i did 3 access list:

access-list 20 permit 172.16.1.0 0.0.0.255
access-list 10 permit 172.16.2.0 0.0.0.255
access-list 30 permit 172.16.4.0 0.0.0.255
and 3 pbr
route-map supnet permit 20 match ip address 10 set ip next-hop 172.16.2.3
route-map blade permit 20 match ip address 30 set ip next-hop 172.16.4.250
route-map main permit 20 match ip address 20 set ip next-hop 172.16.1.4
 
attached them to corresponding vlan interfaces and everything ok they have different gateways to internet but now I dont have routing beetwen them?

Cisco WAN :: 1811 Policy Based Routing

Aug 21, 2012

Last night I had a crack at setting up PBR on my companies Cisco 1811.Joy, I thought, it's actually working.  Alas I was wrong, the addresses were getting translated to our ADSLs external ip address but routed over our EFM.What I want to acheive is to send all HTTP(s) traffic from our workstations over the ADSL (FastEthernet1) whilst all other traffic and VPN goes out over our Bonded ADSL (FastEthernet0).  There is also a minor failover in place for traffic routed to the ADSL in the route-map PBR_VLAN1.  The servers are on IPs 200, 202, 204 and 240.
 
Anyway, I have re-written the configuration and xxx'd and x.a/b/c'd all the IP addresses I want to keep secret. Need to make sure that the PBR is correct, and will do what I want it to?  I have a very small time-frame to get this correct and I dont want to fudge the bucket so to speak.

Cisco WAN :: 3725 - Route-Map For Policy Based Routing

Feb 2, 2011

I have been using a route map to pick WAN exit points (PBR) on a 3725 router.  This have been working fine with /24 networks.  I am trying to pick the first /28 piece out of the 10.1.1.0 network and send it out a different exit from the rest of that network.  I have tried the /28 entry at the start and end of the route map, although I thought the first match would stop any further route map processing.  The entry does not seem to have any effect, as traffic from all addresses in the 10.1.1.0 /24 network exit per the "route-map 10-LAN permit 11" section.
 
access-list 5 remark Ten Dot 1 low 63 IPs
access-list 5 remark SDM_ACL Category=2access-list 5 remark Ten Dot One Low 63 IPs access-list 5 permit 10.1.1.0 0.0.0.63 log

Cisco VPN :: ASA 5505 To Use Router For Creating Policy Based Routing

May 29, 2011

I have an ASA 5505 at each of three locations.  We have VPN tunnels set up between the three sites.  I am currently using a single ISP to control the traffic between the sites.  I am adding a new ISP to the mix.  The goal is to have any internet traffic routed to ISP 2 and all internal traffic routed to ISP 1.The ASA does not do policy based routing (mostly because it is a firewall, not a router).  I need to configure a router that will accept the output of the ASA and route it according to the above rule.  All incoming routing will be done through ISP 1. Any suggestion on the device and the methodology to set it up?  I am planning on doing this in each location.

Cisco Firewall :: Policy Based Routing To ASA5550 Inside Interface?

Mar 4, 2011

Is it possible to establish PBR rules that set the ip next-hop to point directly to the inside interface of the ASA5550?Or, do I need to direct this PBR traffic first to a directly connected router interface and then default route to the ASA?At a high level, here's what we have:
 
ISP 1 - with /21 IP PrefixNo BGP Routing3845 Edge Router - Default Route to ISP 1PIX535 Firewalls (HA) - Default Route to Edge RouterLAN Core/Distribution - Default Route to PIX535 Inside InterfaceAll applications/services use this egress path for PAT/NAT/DMZ/VPN/Etc. 

Here's what we are adding:
 
ISP 2 - with /24 IP PrefixNo BGP Routing3925E Edge Router - Default Route to ISP 2ASA5550 Firewalls (HA) - Default Route to Edge RouterSame connectivity to LAN Core/Distribution 

Goals:Maintain ISP 1 for nowMigrate only end user Internet traffic to ISP 2No disruptions to applications/services using current DefGW to PIX535 

Question: how to best use PBR to selectively direct traffic to the ASA inside interface?

Cisco WAN :: 2811 - Static Routes Need Some Input Policy Based Routing

Aug 13, 2011

I have 2 connections a single T1 for voip traffic only and a DSL line for data traffic.the dsl was migrated to a 2811 with out any issues now comes the time to move the T1 over.
 
on the T1 side I am able to ping the WAN router and the LAN router IP address but nothing behind it.

currently this is the only statment on the router:
ip route 0.0.0.0 0.0.0.0 Dialer1
 
as a quick a dirty to remove the above i tried:
no ip route 0.0.0.0 0.0.0.0 Dialer1
ip route 66.55.110.0 255.255.255.0 Dialer1
 
but the DSL side dropped. we have a 66.55.110.152/29
 
for the T1 i would use the following statement.. we have a 209.98.53.192/27
 
ip route 209.98.53.0 255.255.255.255 65.32.70.177

Cisco Switching/Routing :: Policy Routing Or Offset List For ASR1006s

May 23, 2012

I want to send a particular data stream (source-A  destination-B) through only one of two WAN routers to a remote site. The remote site also has two WAN routers. Traffic from source-A will travel through a core and distribution layer of 6500 L3 switches, running 12.2(33)SXH8, to the WAN routers which are two ASR1006s.  The remote end is the same - two ASR1006 WAN routers to 6500 distribution and Core L3 switches.  All 6500s are L3 uplinked to each other and to the WAN routers.  All traffic from the local site to the remote site routes throuh only one of the two WAN routers.  I want to move only traffic from source-A to source-B to the second WAN router to the remote site.
 
Would it be best to use policy-based routing or an offset list of some sort to accomplish this?  I've done PBR before where you just hand off traffic described in an ACL to a particular outbound port and basically hand carry the traffic to a point in the network where EIGRP prefers the route you want.

Cisco Switching/Routing :: 7609 For Switching / Based On LAN (VRRP / HSRP) Feature

Oct 18, 2011

I am facing an isssues with 7609 for LAN switching , based on  LAN (VRRP/HSRP) feature.Actually  we are having ES+ cards (on 7609) and we are using multiple groups(say  350 vrrp groups) running on the router . the routers are connected as router 1>>> mux(which is working as switches)>>> router2

my questing are

1.  does their will be "multicast packets" (for VRRP/HSRP group) "from backup  router to Master router", when in stable state( ie when Master and  backup are already chosen) , or the packet from backup to master should  be unicast.I know for sure, the packet from master to back is multicast packets denstination to Multicast IP packet and To MAC address.I am not sure but I think from backup to master it should be multicast
 
2. what is frequency of these packets( from backup to master)
 
3.  As i have multiper group on a single interface ( we are using q-in-q),  when the connectivity from router's is broken, then does all the groups  will muticast their active roll in the lan sengment "at once" or it will  be in a groups say 100 groups at once, and after few ms few 100's and  sone ( as is on OSPF or RIP)
 
we are in between troubleshooting I hope we get the ans( Actul problem we are seeing in the router's that we have 2 ports on active routers and 2 ports on standby router , but we are not seeing muticast on 1 port on standby router where as all other 3 ports are seeing multicast packets) [code]
