similar to: Multipath TE

We''re trying to figure out how to have equal cost multipath routing using OSPF (quagga) and have come up with the following... Has anyone done something similar? -- How do you deal with incoming services (mail/web/etc) in such a scenario as below - And does anyone have any suggestions? There''s more detail below.... Diagram and overview: Network A connects to Core1 and Core2

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

Hi List, FYI. We have been using CentOS 6.4 and have 2 vpn/gre tunnels to separate cisco rtrs using ospf. with kernel 2.6.32-358.23.2 We have upgraded to 6.5 bit using kernel 2.6.32-431.5.1 and the exact same configuration scripts for our vpn/gre tunnels. What I see is the first gre tunnel works great and I get an ospf neighbor. The second tunnel comes up and I can ping across it and I see

Hi, I have 2 routers that are connected using 2 gre tunnels over ipsec, and ospf. Ospf sets up the equal cost route, but uses the ''equalize'' in the route. Is there a way to remove/disable packet based load balancing? I would just like to do a flow based load balance? thx jason _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl

Hi, I have the following setup. Two linux systems with two [test] external interfaces encrypted with ipsec [transport]. Two gre tunnels that pass 10.200.0.0/24 and 10.200.1.0/24 network traffic. Testing the balanced tunnels I would setup iptraf on one and ping from the other. The results would be as expected; traffic would be split between the two interfaces. Testing with an ftp transfer of

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

Hello, does anybody know if quagga for CentOS 5.3 is compiled with -enable-multipath? I want to implement ECMP over 2 ISP. Thanks, Cristi Carstea

Hi, I have setup a ECMP route between two linux systems. I do not have the equalize enabled. This would be flow based. After sending a few ftp/scp sessions I noticed that the ''per flow based'' was jumping between interfaces for just one session. My question is, would this be a result of the routing cache changing between the two ECMP systems. If this is the case would

Hi, I have two systems each with 2 two gre tunnels over ipsec. The tunnels are setup to loadbalance using ''ip route''. Using ping from one server to the other I get equal results via the two gre tunnels, but when I try a large ftp transfer the utilization of one tunnel is 90% and the other 10%. The two interfaces are both 100/full. What would be the reason for this, or would

I need to send multicast traffic through a GRE tunnel between two Linux routers. The tunnel works for normal IP packets, but I can''t see how to make it work for multicast.

Hello List, I know 4.9 is ancient history, but unfortunately we have several thousand sites installed. We are in the process of moving to 6.1 when it is released. Right now I have an immediate problem where we are going to install two system at a HQ site. Each of the 2 systems will have two gre/vpn/ospf tunnels to a 100 remote sites in the field. The broadband will be a T3 with failover to

Hi, I have recently updated one of my systems from CentOs 6.4 to CentOS 6.5. This systems is used as a RIPv2 routing server with quagga which is the termination point of some GRE tunnels. While running CentOS 6.4 I see the multicast packages arriving at the eth0 and the GRE tunnel interface. While running under CentOs 6.5 I can see the multicast packages arriving at the eth0 but not on the GRE

Hello, I''ve set up a GRE tunnel between two Linux boxes and it''s working well, with or without IPSEC (under GRE). The problem is that when I have no traffic for some minutes, side A cannot communicate to side B any more, unless side B tries to communidate to side A. The same thing happens in the other direction. For example, side A pings side B. No reply. Keep pinging. Side B

Hello, Please tell me if it's possible to use tinc together with OSPF (instead of static routes in LAN). By OSPF I mean Quagga's GNU/Linux daemon. Namely, I have a group of LANs (private 192.168.x.0/24 each). Each LAN has a GNU/Linux default gateway, 192.168.x.1, that also connects to the Internet via a public IP address (does NAT and firewall for the LAN "behind" it). tinc

Can anyone tell me under what circumstances checksum offloading might cause problems? I have the following configuration: 1. Remote router (OpenWRT) with PC''s on the LAN and a GRE tunnel to the head office 2. Central office with a server running Xen 3.1.2. Dom0 is doing PPPoE and is terminating the GRE tunnels 3.
