HTB.init for zebra BGP
Hi, I have successfully shape bandwidth using htb.init using ip address , but when i try to shape zebra BGP using their ip address and BGP port it can''t match the class for BGP and always get the default class. Here''s my htb.init script in the bridge : #eth0-2:50.bgp RATE=128kbit RULE=192.168.192.163 RULE=192.168.199.22 RULE=*:179 #eth1-2:50.bgp RATE=128kbit RULE=192.168.192.163, RUL...

Linux HA may not be the best choice in your situation. High Availability using 2 sites
...nts hitting the load balancer at one of the facilities, therefore defeating your purpose of redundancy...if they can't hit the load balancer, they can't hit the secondary site! As for Brian's Message: 1) You are right, to a point. I'm not saying that my idea was a replacement for BGP. I even state that by saying "This is no substitution for BGP". 2) You are correct in saying that you need to change in how the world sees you (whether that be in the application or layer3 routing). That can be done at the application layer or at layer 3. But, if you are a small compan...

zebra bgp and shorewall
Hi, I plan to implement a redundant Internet connection using BGP on 2 different Linux Routers. The routing daemon software I will be using is Zebra (zebra.org). I''m wondering if I should have my Linux firewall behind the 2 BGP routers, or could I keep the shorewall on both BGP routers? Has anyone had any experience with this? Any help is much apprec...

PPPoe, Bgp
Refering to pppoe i have next problem : I asked my isp if i can buy a class of real ip`s to be routed by them. They said elegantly it can`t be done . I want opinions . I am using an ADSL connection through a Speedtouch 510 configured in bridge. About Bgp : i asked someone if i can peer 2 different locations on 2 different ip`s using private asn number and he said yes , and what i don`t understood is how can do that peer without using bgp. Thanks. Gladly waiting an answer.

BGP + shorewall on multiISP env.
Hi list, My network was assigned a private AS and my ISP(4) urged me to use BGP ! My Other 3 providers on my Shorewall BOX are typical aDSL lines while the 4th is an 1G optical uplink with 64 addresses. Currently I am in a balance, track mode in shorewall ISP setup.. After I installed - configured and started zebra + bgp my static routing tables got filled with about 850...

Multipath routing

High Availability using 2 sites
We currently have a backup site at a different location to our main site. This backup site mirrors (as closely as possible) our main services, particularly web serving. Is there a way to have the backup site act as a failover for the main site using something like Linux-HA? They are on seperate internet connections with different IP ranges. Thanks -- Tim Edwards

routing strategies for 2 adsl setup
hi all, i have been able to find only a trickle of information concerning possible strategies for a 2 adsl setup using two different isp''s. has anyone had experience in the usa or elsewhere working with their providers to carry bgp tables, or would you recommend/implement a round-robin arrangement? how ? :-) yours sincerely christopher cuse, rhce/ccna ccuse@tiscali.fr redhat 8.0 _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO...

Hardware Requirements for qdisc htb/sfq
...t is working beautifully. My question is what are the general hardware requirements for routing to about 20 subnets (class c), traffic shaping for about 50 fiber customers (TC QDISC), 2 T1s (straight into the Linux router) and about 35MB of traffic out to the next ISP? We are planning to implement BGP sometime in the near future. I have been searching everywhere for some kind of guidelines, but I see none. If anyone could give me a round about answer that would point me in the right direction I would be obliged. This is what I have been looking at: 2.0GHz Dual-Core Xeon, 4GB 667MGz RAM, 2x1Gb...

Zebra, Routing ...
...2 and 3 Box B connects to ISPs 1 and 4 Boxes A and B are both connected to each other and the rest of the network. 1) I would like to set up some dynamic routing in such a way that any given outgoing packet from Box A or B would go out over the ISP that had the "best" path (according to BGP) to the destination. I would like to be able to assign ''weights'' to these routes (based on their available bandwidth), but it is not necessary. 2) I would like to have any given *nix box on the network pick the right gateway (A or B) given the destination of its packets. I unde...

Linux HA may not be the best choice in yoursituation. High Availability using 2 sites
In a nutshell and very first of all, you need at least 2 internet connections. Those ISP must be willing to setup BGP peering between your routers and theirs. Once that agreement has been made, you need to get their AS Numbers and submit the ASN request located on ARIN's website (http://www.arin.net). After some paperwork and money exchanges, ARIN assigns you an AS number. At that point, you can configure t...

Linux HA may not be the best choice inyoursituation. High Availability using 2 sites
One final consideration I forgot to mention, make sure you have a beefy router. Depending on your BGP configurations, if you want to receive all routes from the internet, that can seriously bog down a low end router. I'm not saying you can't get by with a low-end router, just make sure your router can handle the results of your BGP configs. --Todd -----Original Message----- From: cent...

Two ADSL Lines either ECMP or BGP?
Hi - I am trying to find a Linux based solution for one of my clients, I want to bond two adsl lines into one, with redundancy (if one fails the other does all the work). I''ve been looking into ECMP (Equal Cost Multipath), I know BGP would work, but something like ECMP would be much simpler. I have full control of both ends of the connections and I can have both ADSL lines terminate in the same router on each end. I guess my question for the list is; is ECMP a solution for this? I know it does the round-robin distribution of p...
