PBR Using Tracked BGP Route
Hello Guys,
My scenario is:
2 Sites interconnected by 2 MPLS Links and BGP between the routers.
I need some help to force some traffic to be routed using one Link based on Protocol or TCP Port.
But if the link goes down, I need the traffic to be send using another link.
I want to do a PBR using track that validates a specific BGP Route or BGP Neighbor.
Can someone tell me some tips for this case?
Best Regards.
Heleno Fagundes
Hi,
For your two concerns.
**2 Sites interconnected by 2 MPLS Links and BGP between the routers
Do you have some sort of network diagram ????
**I want to do a PBR using track that validates a specific BGP Route or BGP Neighbor.
We can always apply a track and an IP sla monitoring an IP address which the router is receiving from its BGP peer which you wish to monitor.
I am sure if you provide me sample diagram/config i'll be able to give some more descriptive answer.
Regards,
HK

Do you need a cisco router at remote sites when using VRF BGP?
Hello.....
If you could refer to the attached document and read the following... I need to know if a CISCO router is required for each of the sites. OR does the ISP (Provider) provide the only required Router in the private cloud?
We want to replace the Cisco 891 with a PepLink but I don't know if we can do that. Can anyone jump in and help me understand?
When we hear about VRF, its almost synonymous to MPLS VPN. Virtual Routing and Forwarding is commonly used by Service Providers to provide services within an MPLS cloud with multiple customers. The most interesting feature of this is that, VRF allows creation of multiple routing tables within a single router. This means that overlapping use of IP addresses from different customers is possible. Some enterprises use VRF to seggrate their services like VOIP, wireless, geographical location and other varieties.Whether you can replace the 891 device with another device boils down to a single question: Do you need to run BGP with the Service Provider in order to use their service. If you need to run a routing protocol with your service provider, your service is likely a L3VPN (IP VPN) solution ( i.e. you inject your site's routes into the providers L3VPN session, they use MP-BGP+VRF for segmentation within their network).
If, however, they just drop you a L2 connection and provide L2 emulated services ( e.g. L2VPN or VPLS ) across their network, then your device can be whatever you want it to be.
From your device's perspective, it is not VRF aware. That is, it does not know about how the service provider segments your service from another customers. In the L3VPN case, your device is routing-protocol aware. In the L2VPN case, your device is not routing protocol aware and does not need to form adjacency with the service provider's equipment.

PBR using multiple ISP's on 6509
I want to use one ISP for the outgoing traffic for a a specific vlan .if that ISP fails or BGP fails will the outgoing traffic from that vlan takes the other ISP link .
Mostly the answer to your questions depends on how you have configured PBR.
In the most simple case where you have just configured PBR and set the next hop, if the router knows that the next hop is not available then it does not do PBR and will just use the default routing. This probably works ok if the next hop is over a point to point serial interface. Otherwise you probably need to get involved with PBR verify-reachabilty (which gets you into IP SLA etc).
If the router does recognize that the PBR next hop is not reachable (which may require tracking and IP SPA) then the traffic will just use the normal routing table logic.

PBR Multiple Tracking Support information for Cat2960
Hello
I have been investigating for PBR multiple tracking support devices specially Catalyst 2960.
The following is very similar to this information. However it can not be applicable to Cat2960.
[PBR Support for Multiple Tracking Options]
http://www.cisco.com/en/US/docs/ios/iproute_pi/configuration/guide/iri_prb_mult_track_external_docbase_0900e4b1810fe379_4container_external_docbase_0900e4b181525fed.html#wp1056119
But feature navigator can show the following information of this feature.
[Feature Navigator for Cat2960]
PBR Support for Multiple Tracking Options
IOS:12.2(55)SE1
Feature-Set:LAB-Base
You can find it by using the research feature and filter by PBR.
So which is correct ?
Basically Cat2960 can not support PBR or there is any related information based on the feature navigator's info.
Any information would be very helpful.
Thank you very much and Best Regards,
Masanobu HiyoshiHello Julio
Thank you for your precious information!
In my understanding it is conclution that the Catalyst 2960 & 2960S series
basically do not support for PBR. So PBR multiple tracking also do not support right?
Here is the output of Cat2960 and 3750X

So what could you think about the feature navigator's information related to this?
Is it possible to modify it? or request to cisco for this?

EIGRP vs BGP route path selection scenario
I am looking for a routing solution to the following scenario. It is a fairly simple design.
I have two WAN connections between sites A and B. One is a 20 Meg Metro Ethernet Circuit running EIGRP. The other is a 10 Meg MPLS running BGP. What do I need to do in my configuration to make sure that the 20 Meg connection is the chosen path based off the fact that it has better speed and bandwidth? It appears to me that the MPLS is the preferred path even though it is slower.
See attached Diagram:

Doesn't matter what the bandwidth is.
If you want to prefer the 20Mbps links then there are a number of options -
1) if you can summarise each sites subnets then advertise the summary via BGP and the more specific via EIGRP. More specific will be chosen even before AD is taken into account.
2) change the AD of either BGP or EIGRP so EIGRP ends up with the lower AD
3) run BGP on both links although you would still need to manipulate the attributes to make sure the link you want is used.

LMS 4.2 User tracking and router arp table
Hi,
If I have understand correctly, the IP address - mac address matching was made with the arp table of a cisco acces switch if it will made the L3.
My access switch wasn't used for L3 routing, only L2
It's possible to set user track to use the arp table of a firewall or a router for made this matching ?
Thanks a lotAs long as you have a supported Cisco Layer 3 device in your LMS-management domain, you should be able to correlate the IP-MAC addresses in User Tracking (UT).
UT support is not specifically listed for the ASA firewall - I'm not sure it will support that feature if it is the users' gateway.
Useful links:

Monitoring a BGP route and AS-PATH.
Hello.
I need to receive a SNMP trap when a BGP route, received with a specific AS-PATH, disappears from routing table.
Any ideas?
Thanks.
AndreaYou can use EEM for this. Check out the cisco beyond web site for sample scripts that may help you do this.
A company that I used to work for, www.magnus.net had a mature EEM solution for doing this for large network environments. They took a standalone router and using EEM turned it into a route monitor. It would send out notifications when BGP routes of defined attributes like AS-Path diasappeared from routing tables. It was driven by an excel spreadsheet as inputs. It was written by a super CCIE engineer. -
Hi,
I would like to change the bgp router id on my router that dialogue with peers in other AS.
I will use the loopback interface 0 and I have a doubt about the ip address that I can use.
I think that can be a private address in a public addresses domain. Is it correct?
So, I think that it's better I'd implement the ebgp multihop command with the remote AS peers. Right?
Before I do these changes do I have to warn the other peers to permit to change their configuration?Hello,
Changing your router-id will be effective after you reset your connections.
You can use a RFC 1918 address to suit your needs. Be careful not to leak the address to the Internet.
If you use the Loopback interface as a update-source you need to use the ebgp-multihop command for reachability. If you are useing it for a router-id only you should not bother to change the TTL in BGP packets.
It is recommended that you inform your peers about your plans.

BGP Router process is in charge to determine the best path and processes any route "churn". It also sends and receives routes, establishes peers, and interacts with the routing information base (RIB).
(http://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/107615-highcpu-bgp.html)
So I suggest to check what make this process working hard. Depending on that you can choose what to do: bgp dampening (if you have many changes in advertisement received form a neighbor), tuning timer (if neighbor is flapping), using peer-group / update-groups to reduce the amount of job your BGP process has to do to process updates etc...

Dual homed bgp route perference help
Good Morning, sir
I have a question regarding bgp route preference.
We have multi-homed BGP on remote site.
Let's call this site , site_a has verizon and at&t MPLS connection using bgp.
Currently, at&t route is preferred using as path prepend method.
We have addition AS number prepended on link to Verizon to prefer at&t route.
At this time, verizon is idle and not being used.
We would like to utilize this network to pass backup traffic.
We have source and destination address that we would like to pass through Verizon (out backup) link.
Any idea how I can do this?
I created the source/destination with ACL and created route-map matching that ACL and tweaked the local preference.
and since only major route is listed under 'show ip bgp' and not the specific route which I would like to influence,
I didn't see the tweaked route on routing table.
Any idea, anyone?
ThanksGetting the specific route into the routing depends on what is there ie. -
if there is already a route with same prefix and subnet mask in your IP routing table then you are fine.
If there isn't and your routing table does not have even more specific routes covering the whole subnet you want to advertise then you could use a static route either pointing to the next hop IP or the interface on the router used to get to that subnet.
Then you can use a "network ..." statement under your BGP configuration to advertise it and use a route map to only advertise it down the backup link.

How to establish BGP Neighbourship without receiving BGP routes ?
Hi All,
I would like to establish BGP Neighbourship between my internet router and ISP router.
However I would not like my internet router to receive millions of bgp routes from the ISP router but my inside users should access internet via my internet router.
Kindly suggest how to do it.

Also depending on you setup with your ISP, you might not need BGP at all. Sometimes the ISP will advertize your public IP space (i.e. you don't need to), and if they do, all you need is a default route out.
PS:
Also BTW, often for basic ISP connectivity, even when BGP peering with your ISP, the ISP will not send you any routes but a default (because with a single link, there's no need for them). -
Trouble getting BGP route to be primary
We have an MPLS network between locations using BGP. Several locations have a VPN connection as a backup and use OSPF for those routes.
When an MPLS link goes down, the traffic switches over to the VPN connection just fine. But when the MPLS link comes back up, the OSPF route is still overriding the BGP route. I've changed the weights for both BGP & OSPF but still can't get the BGP route to override the OSPF route.
Any ideas as to what I'm missing?

IMHO, you should use the same Weight for both the BGP prefix redistributed from OSPF and received from the BGP neighbor.
And set other attribute (Local Preference, e.g.) to make the prefix received from the BGP neighbor to win when the MPLS interface goes Up again.
Another issue might be though:
When the MPLS interface is Down, you get the OSPF prefix redistributed to your BGP table, And when the MPLS interface goes Up again, you might be advertising this prefix to the backbone. And it can beat the prefix advertised from the remote site. If it's your case, I'd also try to prepend your AS number several times to the prefix advertised from your router to make it less preferred within the backbone comparing to the original BGP prefix.

I have a first generation ipod touch. I use a wireless router to get my internet connection. It is frozen on opening up a website and will not release. Even when I power down and restart it goes back to the same failed connection. Any ideas greatly appreciated. Ray.
- Try resetting the iPod. Nothing will be lost.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Go to Settings>Safari and delete cookies, cach and history.
- Restore the iPod -
Can I use a wireless router to share a USB broadband connection
Hi - I have an emac or a mac minin which have a USb boradband modem. I use airport from the emac to allow me to connect from an airport enabled powerbook when it is at home.
Rather than getting an airport card for the mac mini, could I use that as the primary conection to the internet (via the USB modem) and then get a wirless router (eg netgear MR814) an I use a wireless router to share the USB broadband connection to the 2 airport enabled macs?
Or do I either:
1) need to get airport for the Mac Mini
or
2) Get a ethernet modem to plug into the wireless router
Any advice appreciated?
Tommy bananaSorry my first post was a little unclear.
Hi - I now have an emac and a mac mini, both of which which have a USb boradband modem. I use airport from the emac to allow me to connect from an airport enabled powerbook when it is at home.
So that all can connect at the same time and rather than getting an airport card for the mac mini, could I use the mac mini as the primary conection to the internet (via the USB modem) and then get a wirless router (eg netgear MR814) an I use a wireless router to share the USB broadband connection to the 2 airport enabled macs?

How to use two versions routing in SAP on different time period?
Hi PP experts,
There is a material Material-100 linked Routing-A and Routing-B. I would like to use Material-100/Routing-A combination during period 29.04.2015-30.05.2015, and using Material-100/Routing-B combination during period 01.06.2015-31.12.9999.
Could you please kindly guide me how to do it in SAP? Thank you.
Best Regards,
Bu FanchaoHi Amit,
Below is my thinking, please kindly help me check.
1. Due to routing-A is existed in SAP with period 29.04.2015-31.12.9999. So I need to change the valid-to-date from 31.12.9999 to 30.05.2015 via ECM.
2. Create routing-B by CA01 with period 01.06.2015-31.12.9999.
3. Create production-version-1 with routing-A/BOM during 29.04.2015-30.05.2015. And Create production-version-2 with routing-B/BOM during 01.06.2015-31.12.9999.
My new question: Do I have to create production-version to achieve it? Does SAP system can choose routing automatically without production-version?
Best Regards,
Bu Fanchao
