I believe this is what you are looking for: set egr_drp_ctr $result expr {$egr_drp_ctr + 100} sumof if {$egr_drp_ctr >= $sumof}     puts "Alarm" It may need correction on the syntax , but thats the logic. ... View more

Hi Michal, Yes, it is possible and I am currently using that hierarchy on my network. My DATA Vlan uses ISP1 , while INTERNET uses ISP2. I have 2 Hub's on my HQ, each HUB has 2 Tunnels with 2 ISP providers, and the branches have 4 Tunnels ( 1 Tunnel primary for DATA via ISP1 through HUB1, 1 Tunnel secondary for DATA via ISP2 through HUB2, and the same goes for INTERNET vlan just that INTERNET vlan has ISP2 as it's primary link, in order not to overload ISP1 and utilize both links at the same time). The Hub's do the splitting of the traffic, I'm using Offset-list ( EIGRP ) to order the traffic going for DATA via ISP1 and INTERNET via ISP2, and then as for the returning traffic I am using summarization on the Hub's Tunnels, you could define your internal vlans with a smaller metric on your primary ISP Tunnel, while increasing your internal vlans metric via your secondary ISP Tunnel and lowering the metric for 0.0.0.0/0 subnet ( which defines everything else, in this case, the INTERNET ). It may be overwhelming in the beginning , and it took me some time to implemenet this, but I have to say it was worth every minute i've spent doing it Cheers ... View more

The same results comes from c871 and c1811 too. Cisco IOS Software, C870 Software (C870-ADVIPSERVICESK9-M), Version 12.4(15)T10, RELEASE SOFTWARE (fc3) Cisco IOS Software, C181X Software (C181X-ADVIPSERVICESK9-M), Version 15.0(1)M, RELEASE SOFTWARE (fc2) ... View more

Hi gavinspost , I had the same issue as you with matching the pattern, you need to use wildcards to escape the brackets as it gets parsed as a command otherwise i think. Here is how i've done it: event syslog pattern "%RTT-3-IPSLATHRESHOLD: IP SLAs.*3.*.*Threshold exceeded.*" ... View more

Hi Jay, Thank you for your time to read this and contribute. 1) I have separated DATA from INTERNET traffic using offset-list at the spoke level, and at the Hub's.However, I couldn't think of a way how to remove the unnecessary routes on Hub1 for the INTERNET subnet, it would have been better if Hub1 had only DATA routes.That doesn't cause problems, not yet..but its not what I wanted to achieve. A little nice feature i've added was adding offset-list on the stack switch, to advertise my Data Center subnets down to the spokes , I have created two acl's , and whenever I need to advertise a new network from my Data Center, I just have to add them to the corresponding acl on the stack switch. 2) Hub advertises summary routes down to the spokes & the stack switch with different metrics.Hub1 advertises DATA subnet with a metric of 1, and INTERNET subnet with a metric of 110, that way it will stay a backup Hub for INTERNET subnet, and so the other way around goes with Hub2. You can see the summary routes on each Tunnel interface at the Hub level, and at the interface connected to the stack switch , so the stack switch will only have summary routes. ( if this can be achieved in a easier/shorter way, that would be great because its making my configs a bit long ). Here's a quick description of my Tunnel interfaces: Tu0                            up             up       *** Primary for DATA via HUB1 - ISP1 *** Tu1                            up             up       *** Secondary for DATA via HUB1 - ISP2 *** Tu2                            up             up       *** Primary for INTERNET via HUB2 - ISP2 *** Tu3                            up             up       *** Secondary for INTERNET via HUB2 - ISP1 *** Cheers ...

I appreciate if anyone could give me some advice on this matter, i think i'm quite close to finishing the lab but a small push would help me very much. Thanks ... View more

Thanks for the link, though I can't find my topology there because they use both hubs for all the branches, or just a simple fail-over Hub. What i'm saying is, I want the Data and VoIP subnet to go through Hub1 always ( Except if Hub1 goes down for technical reasons ) , and the Internet subnet to go through Hub2.So when i'm at the stack switch, I will see only a few summary routes. What i'm trying to accomplish is, I want to summary routes for example 192.168.0.0/16 ( Data and VoIP ) and 192.169.0.0/16 ( Internet ) down to the stack switch , also at the branches to shorten the routing table.I accidentally redistributed a summary route to the branch router, and I actually liked it.Because that way , the branch router won't have thousand of routes in its routing table, instead it will have only 2 summary routes, one for 192.168.0.0/16 and one for 192.169.0.0/16. On my current lab configuration i have 4 Tunnels configured on the branch router, and 2 Tunnels on each Hub. Let me explain the 4 Tunnels.. Tunnel0 is primary for Data and VoIP traffic, it has its Bandwidth set to 5000 and a delay of 1000.Tunnel0 points to HUB1 via ISP1. If ISP1 goes down on the branch router, Tunnel1 should come up , which points at HUB1 , but via ISP2.I've set Tunnel1 bandwidth to 3000 and delay to 1050, so that way I can seperate T0 and T1 from each other and not load balance. Now here comes the 2nd part, theres T2 and T3 as well, which does the same thing as T0 and T1 , except its routing for the Internet traffic. And when T0 goes down, T1 is up but with a higher metric ( because of its delay and bandwidth ) , while T2 has its bandwidth set to 5000 and delay to 1000, it becomes primary  , which I dont like at all. It's all about logic, but I can't find the right logic for this now. I hope you understood the topology. Cheers Uran ... View more
