similar to: Best setup for redundant routers.

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

Before I start, I don''t want to do ECMP or simple bonding ... I have multiple Internet connections available to multiple boxes on one of my networks. Box A connects to ISPs 1, 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

Hi all, I am trying to come up with an architecture that has some redundancy. The idea is to hook up the two GbE LAN interfaces of a CentOS server to two Gigabit Ethernet switches. In case one switch goes down, there is a redundant path (the server is redundant too). Here is the idea: ----------- | GbE | PCs

Hi all I have installed vyatta system, (vyatta-livecd-vc4-alpha2.iso ) on top of Centos5. Our system requirement is, * Centos 5.1 (2.6.18-92.1.10.el5xen ) * 2 Gb RAM, * x86_64 And cpu information is as follow, [root at turtle4 ~]# cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 107 model name : AMD Athlon(tm) 64 X2 Dual Core

Hi, The network topo looks like this: the original network: router1 router2 | | |----------------OSPF------------| the target network: (we need to insert a transparent firewall between these 2 routers, so a proxy arp is set up on firewall to bridge router1 and router2) router1 firewall router2 |

My setup: LAN A | |-- Wireless-r1 --| |-- Wireless-r2 --| ..................| .................LAN B LAN A is my primary (external) LAN. LAN B is my wireless LAN. LAN A does iBGP and OSPF routing. Each wireless router does the following: 2 Bridged Ethernet + STP connections to LAN A 2 Bridged Ethernet + STP connections to LAN B 2 VLANs on LAN A 5 VLANs on LAN B UCARP on each wireless

Hello, First , thanks to Tom for it''s great job ! Netfilter is really easy and powerfull with shorewall. So, I have configured two firewalls whith shorewall using keepalived for the redundant VRRP stuff. FW-a is MASTER and FW-b is BACKUP. Everything works correctly and FW-b upgrade to MASTER when FW-a is down or disconnected. FW-b downgrade to BACKUP when FW-a comes back. But when I

Hi, all! Can I enable multicasting via shorewall? I have router with Gentoo Linux (one interface to ISP, one with alises - to local network). Shorewall work perfect! But now I need setup Quagga (zebra) for dynamic routing between one more router via another provider. All routers daemons (zebra, ripd, ospf) used multicasting. In my configuration already enabled allowBcast and etc.

Hi all, I am using a redhat 8.x linux box configured with zebra routing software which is also configured with ospfd I have 2 backbone routers running ospf connected to different isp''s I have 3 local routers also running ospf within themselfs and also with the 2 backbone routers (all are linux boxes) router A - backbone router 1 router B - backbone router 2 router C - local router 1

Hi Everyone, I have a routing situation where Tinc looks like it could come in extremely useful, but I have a query I hope someone can cast an eye on, as I'm unsure whether Tinc can help me here. I currently have a Quagga OSPF linux router which connects LAN A to LAN B over the quickest available of two routes (both routes at both ends connect to Quagga boxes to prevent collisions). One of

Dear Sir, I have point-point ethernet connections to my linux boxes on which I am running Zebra OSPFD. I am unable to understand the output of the tcpdump. Please clarify the terms in the output. The output of the command tcpdump on BOX 1 is as follows: I have also shown a part of my network below. 14:0831.849801 eth0 M 192.168.2.2 > 224.0.0.5: OSPF v2-hello 48: rtrid 192.168.4.2 backbone

Hi list, I have a problem I thought was simple first, but now I''m stuck. In a nutshell, it''s about redundant uplinks at an outside location. Crude ASCII-Art follows: Internet | | +------------+ | cisco with | | uplinks | +------------+ | | ATM interface +----------+ ... | alvarion | | | wireless

I have a fairly simply laid out network that could easily use static routing. However, I plan to expand quickly and don''t wish to spend the better part of my life maintaining static routes. INTERNET | --------- Gateway | - LAN 172.16.1.x | - LINK 192.168.1.1 --------- |<----wifi --------- router 2 | -LAN 172.16.2.x | -Link 192.168.1.2 ---------

Hello all, Some time before Christmas, a project was started. The task was to enhance an existing LiveCD solution with User-mode Linux. A number of requirements was stated, where the greatest challenge was to fit 10 virtual routers within an old no-name PC with only 256MB Ram. And the solution must still be run from a LiveCD. Thanks to Xen, the task was possible to complete. -But, what does it

Can someone point me for good VRRPD (rfc2338) implementation on linux. Some stable and live project Thanks _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

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

Well, this is a major pain in the ass. I got realtime static working for sip.conf. 'Great!' I thought. That was until I realised I couldn't use it. Our Asterisk systems are using OSPF and listen on interface lo:1. Asterisk doesn't like to use an interface name for it's bindaddr setting, so you have to put the IP address of lo:1 in there. If you put in 0.0.0.0, it seems to

What shorewall rules would be required to allow the OSPF routing protocol to pass fw<->loc? Any suggestions would be appreciated. Ben

Hello guys, Sorry to bothering you. I had a small network with one ISP and firewall. eth1 -> Is connected to my ISP eth0 + eth0.1 , eth0.2 and etc are my local networks. All my network accesses internet via eth1. My routing table looks like the following : 213.194.242.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 10.123.20.0 0.0.0.0 255.255.255.0 U 0

Hi, I just set up tinc between two hosts (for now). All seems to work fine, but now I run in to a routing issue: I gave both of my vpn routers an IP in the 172.16.100.0/24 range, and used the Subnet-directive to inform tinc of this. This works fine, I can ping both hosts from both sides of the vpn. Ofcourse both vpn routers give access to other subnets, but they don't know the IP-ranges
