Hello Anyone used Zebra routing daemon and created virtual routers before? Is it possible to run OSPF/BGP on each virtual server and get them to talk to each other? I''m new to Xen and I need to know... I will be trying this out in the coming days and I want to know about any pitfalls to avoid. -- Nonchalantly yours GobbledeGeek [Every thing but Gobbledegook.. !!]

Hello Can the linux kernel detect interface up line protocol down situations? Is there a object tracking feature in iproute ? ex: interface, route (next-hop down) etc... How about with sync serial cards running hdlc/ppp? This will have to be a part kernel feature and part device driver one I guess... (device data structure will have to provide flag.. i.e) -- Nonchalantly yours GobbledeGeek

Hi Andreas! I mainly understand what you mean, but best for me would be if you could make an example from the script I have. I know I did something wrong into it, but I still can''t see the error. If you could fix the error from my script that would be much appreciated. Looking forward to hear from you, Daniel Phlander lartc-request@mailman.ds9a.nl wrote: Send LARTC mailing list

Hi Andreas! I mainly understand what you mean, I tried to fix something on the script, I don''t know if I did it well. Can you take another look on it please and if is wrong to make the corrections directly on it so that I see where the mistake is... With this script I want to make limits for IP class 85.120.48.0/25 for international traffic in 256 KBps classes and for metropolitan

Dear List. I try to build multipath connection w/ load balance to internet with two different gateway; My system is RH-8.0 with iproute-2.4.7-7.90.1.rpm and Kernel-2.4.26 (patching with Julian A. patch),and follow guide from http://www.linuxvirtualserver.org/~julian/nano.txt, The problem is; when i try to connect to Internet form gateway machine it;s success , but only one interface is

I am running 2.4.20 with Julian Anastasov''s patches (routes-2.4.20-9.diff), iptables v1.2.6a, iproute2-ss010824 on Debian. I have set up our internal gateway to multihome 2 T1''s as described in http://www.linuxvirtualserver.org/~julian/nano.txt . The only difference is that I use multiple IP''s on the external interfaces. EXA A.B.C.225 --------------------

I have a doubt. If you use such a script monitoring the link status with ping and then reconfiguring, why do you need the DGD patch? You need to do some reconfiguration (change multipath to a single default route) anyway if you use the script, right? Also, the DGD patch uses src to lookup the routing table entry, but if you have a dynamic IP for the WAN interface (PPPoE, DHCP etc), this approach

Hi, I think I found a problem in iproute or ubuntu kernel. I think that the "ip route get" returns wrong interface and gateway in an multipath routing environment on Ubuntu 6.06 LTS. I reported it also to launchpad as a bug: https://bugs.launchpad.net/ubuntu/+source/iproute/+bug/105521 The easiest way to reproduce it is to start an Ubuntu 6.06 LTS Live on a system with three

Hi William. Thanks a lot for your help. Im having some trouble recompiling my kernel after a installed the patch. Im running RH 7.3 with kernel 2.4.18-3. The patch I installed is routes-2.4.16-6.diff. I got no errors installing it. I added the multipath support, and recompiled it. The make dep and the make bzImage went fine. I got error during the make modules. These are the errors:

I have 2 cable modems on a server (Linux 2.6.22). I use multipath, so the route is something like this: default nexthop via 201.6.102.1 dev eth1 weight 256 nexthop via 201.6.107.1 dev eth2 weight 128 The first one (eth1) has a higher priority, then when it goes down, I can "ifconfig" the interface eth1 down and Linux automatically detects the "dead"

Hi all, I have setup two multipath route tables on my system for doing failover routing, What I want it''s that if GW at route1 of the MP is dead, traffic goes by route2, for doing that I have created the multipath routes as follows: ip route add table mail.traffic proto static nexthop via ${GW1} dev eth1 weight 1 nexthop via ${GW2} dev eth1 weight 250 But it does not run as I

Previously I attempted load balancing between 3 interfaces with limited bandwidth but a common gateway with much more bandwidth using QoS and teql. This had little to know luck because routes never seemed to come out right. Someone pointed me in the direction of http://www.ssi.bg/~ja/nano.txt to try and set up a multipath route instead. After setting this up it seems that all of the routes are

Hello. I have the problem that I have two gateways on the same subnet, 80.237.244.1 and 80.237.244.33. Both gateways are 100 MBit cards, so I have 2 times 100 MBit to the Internet. The NIC in the server is a gigabit-card, so this card is easy able to use both gateways for outgoing traffic. Now I just want to use both gateways for my outgoing traffic but no matter what I do, it doesnt work. I

Greetings, I wanted to ask the list a question about dead gateway detection. I''ve followed the wonderful writeup by Christoph Simon on how to use Julians patch for dgd on two loadballanced connections, but I don''t want them loadballanced. How can I setup two default gateways but always have one be the preference unless it goes down. Once the dgd code sees that have it switch

To begin with I have not applied and am not using the patches provided by Julian Anastasov. http://www.linuxvirtualserver.org/~julian/ I do not believe at the moment they apply to the problem I am having. If they are I will go through the process of applying the patch. They mostly have to due with what happens when a connection dies. At the moment both of my connections are live, and I am having

Dear all, First please excuse me for my very bad english. I''m curently setting up a gateway (linux 2.6.7) with load balancing ( multipath ). I access them from lan and my external interfaces are NATed. I''m used iproute2 as described in the LARTC and nano howto. My problem is that connections are well balanced but often, long connection are break because the default route

I''ve been reading about multipath routes and found something that no howto I saw mentioned so far: multipath algorithms. The kernel has the followings: # zgrep MULTIPATH_ /proc/config.gz CONFIG_IP_ROUTE_MULTIPATH_CACHED=y CONFIG_IP_ROUTE_MULTIPATH_RR=m CONFIG_IP_ROUTE_MULTIPATH_RANDOM=m CONFIG_IP_ROUTE_MULTIPATH_WRANDOM=m CONFIG_IP_ROUTE_MULTIPATH_DRR=m CONFIG_DM_MULTIPATH_EMC iproute2

Hello, LARTC mailing readers, I hope u can help with this mysterious issue i''m having with my linux box acting as a router. Scenario: Linux running 2.6.8.1 /w julians patches /w support for multipath routing Latest iproute (iproute2-ss040702) 4 NICS ----------------- | x eth0 (63.43.x.x) network mask (255.255.240.0) | |

I have a private lan that is connected to the world via 3 dsl lines. I put up a linux box that handles all the dsl lines, lan gateway and all is working well...until...one of the dsl lines goes down. My routing table is: x.x.x.x dev ppp0 proto kernel scope link src x.x.x.x x.x.x.x dev ppp1 proto kernel scope link src x.x.x.x x.x.x.x dev ppp2 proto kernel scope link src x.x.x.x

Hi everybody, I''m not so glad because of the error I describe in the subject. I have two internet lines and I want to do equal cost loadbalancing on the two uplinks to the internet. This is what I do: ip route add 200.200.200.0/24 dev eth2 table 200 ip route add default via 200.200.200.254 dev eth2 table 200 ip route add 100.100.100.0/24 dev eth1 table 100 ip route add default via
