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 &quot...

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 | | | | |------OSPF-----| |---OSPF-----|...

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 the routes involves connecting over a wireless bridge (which can't be set to routed mode) and the other connects over a routed w...

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

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 our side...

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 --------- |<----wifi --------- router 3 | -LAN 172.16.3.x | -Link 192.168.1.3 --------- OSPF seems to work however when connected to the LAN on either router 2 or 3 I get periodic time outs. It looks like the routers keep trying to elect a new chief and the little indians are getting extremely confused. Does anyone know what would be causing this and how I might avoid it. I tested it on...

...rmation about having redundant, automatic failover routers and pretty much decided on VRRP for the IP address failover mechanism. I am having a bit of a problem sorting out what will work best for automatic routing propagation between the two units and have been looking at the possibility of using OSPF to accomplish this to avoid having to enter routes into two different routers. Would OSPF work well for this? Are there better options? Thanks for any info, Shane McKinley

Hi all, I am currently trying to emulate a satellite link, via Netem, on a testbed which is OSPF-enabled. I''d like to set up a Netem box between two routers. Since all routing between routers is dynamic, I''m wondering how to set up OSPF on my Netem box? Could someone indicate me if it is feasible and give me some guidelines to possibly do so? Thanks in advance, Vincent....

...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. Copy of configuration with logs in attached file. Please, help! Andrew.

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 VLAN (5). Quagga - zebra, bgpd, ospfd (on LAN A) UCARP provides a virtual IP address for the gate...

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 (has 3 subnets...

...uld have an idea about this. Thanks in advance ! Best, -----Forwarded Message----- Hi There, I''m new to quagga and to dynamic routing in general, so please forgive me if my question are foobar. I''m trying to setup a linux router (Fedora Core 2, kernel 2.6.5) with Quagga & OSPF. Our linux router is also a firewall, doing advanced policy routing (eg, it''s having multiple routing tables, other than ''main''; all used for specific purposes.) This linux router is directly connected to a CISCO router, doing ospf. In order to use OSPF routes on the...

Hello All, Ive been doing more and more research on trying to setup a cluster/load balancer for Asterisk. All the Asterisk boxes would be using a config that is the same between them all (via a DB), but we want one location to point the phones to, and from there that machine/device will send it to a Asterisk server so the call can be processed. I know you cant balance the whole call, ie: once the

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 listen on the first interface it finds, probably eth0. You can't do that with OSPF because it...

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 dr...

...had a BGP AS#, but I don''t. Is it possible to arrange ''private'' peering arrangements so I could download the BGP views each ISP had without needing a public AS# (don''t tell me I should get one -- it probably won''t happen). Am I correct in assuming that OSPF (which I currently have installed) is the best way to handle route distribution within the network (#2 above)? Is there a ''good'' way to configure it with as few rules as possible? I''m going to send this to the Zebra list as well once I find my address book entry for the...

After installing Zebra for ripd to get win2k routes I am getting this May 20 23:24:20 ns1 kernel: Shorewall:net2all:DROP:IN=eth0 OUT= MAC= SRC=64.42.53.202 DST=64.42.53.207 LEN=92 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=520 DPT=520 LEN=72 May 20 23:25:25 ns1 last message repeated 3 times I am new to zebra, so I am assuming that this is broadcasting to windoz for routes weird !!!

...itching to the backup line should work automatically. There are link networks between the linux box and the DSL modem and between the linux box and the base (subscriber is acting as a bridge). We control all the equipment, including the cisco. So I thought I''d use quagga and build a small OSPF or RIP between the linux box and the cisco where the linux box announces the target net. The wireless route would have higher priority because of the higher line speed. But how do I set the "default route" on the box? I don''t want to redistribute BGP into OSPF on the cisco, it k...

I''ve got a linux router pushing 600-1000 pppoe connections through it. I''m getting a screen error "Neighbor Table Overflow" after this box has been up for between 1 week and 1 month. When this is happening, routing slows to a crawl if at all. Then dies. I''ve added: # Added to stop "neighbor table overflow" messages in the kernel
