Dynamic routing?

[ela002]

Hi,

Is it possible to add quagga for BGP support?

It's rarely used thing, so it would not be added to the firmware. You may need to compile it yourself.

Hi Oleg,

Maybe you can give me a hint?

I have the following scenario I would need your help with:

ADSL router (M) with 2 APs (Asus A1, A2) hanging off.
For Internet Backup I have a 3G router (Asus A3) connected to (M).

All LAN devices on same subnet. See drawing attached.

In the case of (M) going down I want to have added a patch cable from (A3) to
(A1) and (A2) and resp. routing.

meaning if Link A3<->M is down, then Links A3<->A1 and A3<->A2 to be activated.

How can I achieve that? quagga (RIP or OSPF..?) and how so? Thanks and best regards.

or can I use a second peer with the Asus wl-500gp to switch between two links -in the event of one link down- as I think this works for Cisco routers? Thanks for any help or advice!

I think I recall from reading the specifications of the wl-500g that it supports dynamic routing (rip-1, rip-2). in what sense is this realised in the router? I can't see that it is accessible via the Web interface, nor do I see any commands or daemons when logged into a shell account. I am running firmware 1.9.2.7-5a.

I'd really like to get dynamic routing up and running, is it perhaps available through any additional packages?

[Oleg]

I'm wonder, why do you need this.
Anyway, it's no longer supported since 1.8.x.x firmware.

I'm using several of these routers to connect me to an ADSL Internet connection via two wireless hops. A lot of the equipment will therefore be located at a couple of different neighbours within 3 km. Should anything happen with this equipment, some cables get unplugged, the neighbours shut down the system and go on a vacation, it would be neat with a dynamic routing function that realised that the ideal Internet connection has gone down and reroute traffic through another router connected to my phoneline as a backup.

To separate the LANs at the different neighbours I will set up in the boxes in router mode and apply a packet filtering rules to isolate traffic within the different sub LANs from the Internet traffic that is allowed to pass through.

Regarding this I have another question: it seems that the DHCP server in the router is within a service called dnsmasq with an appropriate config file. Is it possible to configure this to supply IP addresses from different subnets to different interfaces?

Also, is it possible to set the IP address individually of all three interfaces eth0,eth0.1, and eth1?

Well, this setup is not so easy to manage. Your neighbours should also run routing daemons, as otherwise packets destined to you will not be able to reach your host.

sure, read dnsmasq manual.

sure.

anyway, the stock firmware is not suitable for this things, consider using openwrt instead. it has quagga as well.

I know that the setup isn't easy to manage, that's what makes it fun I will be using wl-500gx devices at all three locations, so I was planning on running the routing daemon on all of them.

Is openwrt is the same firmware that runs on the Linksys units? If so, have a easily installable on the Asus devices? And what is quagga?

Thanks for the input, it's very much appreciated.
