Good times! We are starting to play around with VMware SRM and they "virtual" subnets that supposedly have to be able migrate from site to site in case of a failure of the local hardware (or software). Seems like to do that I'd have to run a software router on a VM that would redistribute the "virtual" subnet into the physical routing domain. does any one have any suggestions for a software router? I'm running EIGRP on the net, so I guess nothing will speak that, so I'd have to redistribute OSPF. Any OSPF software router software suggestion would be much appreciated. Or if anyone had implemented "floating" subnets, any other suggestions or what to look out for would be also much appreciated. Thank all in advance, -- Andrey Khomyakov [khomyakov.andrey@gmail.com]
Really not core network related as it never touches a wire, let alone the core, but try www.xorp.org. Andrew On 06/01/2010 04:50 PM, Andrey Khomyakov wrote:

Mikrotik would fit the bill.

Vyatta has a VMWare image. Have used and is pretty good. http://www.vyatta.org community edition or http://www.vyatta.com commercial supported. Mike

I second Vyatta. I've played with it quite a bit and found it to be extremely functional. Ernest On Tue, Jun 1, 2010 at 4:50 PM, Andrey Khomyakov <khomyakov.andrey@gmail.com

Standard OS + quagga, openbgpd, or other. Vyatta should be great, if you are able to compile the vmx drivers for it.
Hopefully you are not planning to forward high-PPS traffic through a single VM; vNICs are potentially a serious bottleneck in that scenario. If traffic is not trivial, I would suggest using third-party next-hop routing, that is, with VM-based routers removed from forwarding path, by acting as route server, or announcing as next-hop another (real) third-party router's IP instead one of its own IPs (requiring all 3 routers to share a subnet). Or investigate layer 2 extension of an upstream subnet via L2TPv3 pseudo-wire service, or Cisco OTV, etc.... then design failover scenario to not require a VM involvement. Another thought is OSPF /32 host advertisements on some 'beacon' VM(s), with tracked routes for 'virtual subnet' selection, instead of a "router" VM. Those are some vague thoughts... I'm just saying, almost anything, other than having a VM forward packets for subnets, if it is avoidable, even tunnelling -- on a non-VM router... :) -- -J
