[LARTC] What failover solution for advanced router ?

[LARTC] What failover solution for advanced router ?

[Tomasz Wrona]

Hello,

 Could someone experienced suggest good solution for failover
 advanced router ?

 The router for which I need redundancy is quite complex:
 1) has 5 interfaces
 2) uses the same network and the other network IP aliases on some interfaces
 3) uses bunch of policy routing rules
 4) uses proxyarp feature on some interfaces
 5) uses complex iptables setup [propably not important in this issue].

 What I need to achieve is basic failover, I do not criticaly need
 transparency failover.

 I found some docs about ip_takeover with fake utility but
 propably it has too weak features [and uses old ifconfig]. Also found vrrpd tool but
 I am confused if I can really depend on it for such a "multithread" configuration.
 Finally I consider using Heartbeat with set of scripts for "manual"
 bringing up all interfaces on preconfigured spare router in case of
 primary one fails.

 I would be very gratefull for some discuss about proper solution for my
 case.
  

Regards,
tw

Tomasz,

Have you looked at keepalived?  It has a rich feature set, is actively
maintained, and can function strictly as a VRRPD.

One intelligent aspect of design allows for two routers to be in active
use each functioning as a backup for the other.

It sounds like your situation is rather complex, but I imagine with some
creativity, you could configure keepalived to your advantage.

  http://www.keepalived.org/
  http://www.keepalived.org/pdf/UserGuide.pdf

I'd recommend reading the user's guide for some ideas.  Given your
description here, I'd suggest reading section X (Case Study) very
carefully.

Good luck,

-Martin
