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

Hi, Hopefully this won''t be too off-topic (I''ve seen both bonding & vlan mentioned on the list, but not really together). I''ve tried to get bonding (2 x 100Mb EEPro, but will want to try on 1000BaseT) and vlans to work together, but without luck. I can get them working fine (seemingly at least - I didn''t tried bursting on the bonded port) individually.

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

Hello, I hope i wont make it too complicated and sorry for my englihs... The company has multiple connections to the internet ADSL + CABLE + XDSL... and i only want to use two for load balancing for now. I have read the HOWTO and i got it up and working it works great but i still have a few questions if anyone could help! the setup is: ADSL on ETH0 and CABLE on ETH1 When i load balance on

I have a dual-homed firewall. It has 2 Internet connections, provided by different ISPs (each with an associated IP address). The 2 Internet connections are connected to the same physical interface. The 2 Internet connections do NOT have equal bandwidth How do I configure the SNAT/MASQ and ensure sharing of the gateways with the correct ratio of usage and with the correct source IP address? I

Hi, With kernel 2.4 I was able to use equalize to send our outgoing packets to two different routers (our isp supports this setup), like this: ip route add default src ip.a.dd.rr equalize nexthop via <router1> weight 1 nexthop via <router2> weight 1 The two routes were used equally on a per packet basis, not per flow or per cached route, but per packet, each line has 800k upload

Hi, I am tring to us ip route to load balance between two interfaces. ip route add equalize 10.200.1.0/24 nexthop via 10.200.0.2 dev neta nexthop via 10.200.0.2 dev neta2 Where neta and neta2 are gre tunnels. Testing show that packets travel in a single sided manner. Do I need to use the multipath (IP_ROUTE_MULTIPATH_CACHED) module? thx jason

I figured I should post this because before I went to do it I searched the web for caveats etc and didn''t really find much. So anyway, I set up bonding + vlan for a project. Computer is dell powerdge 350 with 2 intel 82559 10/100 nic running stock 2.4.20. I tried both the eepro100 and the e100 drivers for the nics, both work 802.1q and bonding are modules. Switch is cisco 2924xl-en

hi for those who was fallowing this topic I can say that IP_ROUTE_MULTIPATH_CACHED must be disabled! After few tests I''m quite sure that this was cousing my problems. Now I''m using 2.5.15 kernel without patch of Julian Anastasov and load-balancing is working. lartc split-access how to and http://www.ssi.bg/~ja/nano.txt now both are working fine Now I will try to use fwmark

Hi everybody! I''m trying to implement the load balancing for a LAN with two ISPs. I''ve installed a Suse Linux Enterpise Server 9 with iproute2 for that porpouse. The server have two NICs, one of them is for both the LAN and ISP 1. I''ve setup both NICs with YAST (if I use ip for this, then the whole thing doesn''t work!) and execute the following commands to

Could whomever is in charge of the lartc mailing list please change it to add the header: Reply-To: lartc@mailman.ds9a.nl Every other list I''m on is setup so that by default replies will go to the list. When replying to lartc emails I notice myself and others constantly forgetting this list does not behave like the rest, and that we have to either do a reply-to-all, or manually enter in

Hi all :) there is somekind of strange Routing problem that im getting with Linux-2.6.16 and iproute 2.6.16 , when i use command like : ip route add default nexthop via 1.1.1.1 dev eth0 nexthop via 1.1.1.2 dev eth1 all packets goes on 1.1.1.2 ( always last interface ) , whats is the problem ? this situation also tested with equalize flag , on two physical interface and etc ... -- Lady Luck

Hi All, This is out of the topic question, but I''m hoping that you can help me. If for example I''m going to install a Fedora 4 64-bit with 8 to 12 Gig of physical memory, how much swap file of directory do I need to create? Thank you very much, Wennie

Hey, I''ve been scouring the web these past few days trying to find a suitable technique to load balance my network. Unfortunately I think my setup is very uncommon, so I''m looking to you guys to see if you can help. I currently have 2 ADSL modems, provided by the same ISP and terminating on the same gateway (I think having the same gateway is what is causing the problems, since

There has been numerous threads etc regarding this but all that has left me is more than a little confused :-(. I have setup and environment consisting of two OpenVPN tunnels and wish to load balance at the packet level between them. I am currently running on Linux edm 2.4.21-20.EL.c0custom #2 Tue Oct 12 08:52:23 BST 2004 i686 i686 i386 GNU/Linux And have install Quagga at each end to provide

Hi There, We currently using iproute2 for load balancing. However we need more upload speed as we load balance over 3 dsl lines. I''ve been looking for a way to combine the upload speed to more faster. Found a site called www.upstreaminter.net where these guys bond the adsl channels to improve uploads, Since downloading is problem as its need to know the ip address of the downloader they

Hi, I have searched the archives on the topic, and it seems that the list gurus favor load balancing to be done in the kernel as opposed to other means. I have been using a home-grown approach, which splits traffic based on `-m statistic --mode random --probability X`, then CONNMARKs the individual connections and the kernel happily routes them. I understand that for > 2 links it will become

Hi, I am not sure if this problem has already being posted, but I haven''t found any solution. Excuse me if it''s a repost but would appreciate any pointers. I have newly configured Multipath default route. I have 1 local connection and 4 internet connections. I am using kernel 2.6.7 and have applied Julian''s relevent patches. When the next hop is down,
