I think you will find (1) at the top of the list (i.e simplicity taking the ruling position) shortly followed by 4B , in many cases the provider will give the customer a private ASN (even the same private ASN) to make network management simpler. Dave > On 17 Jun 2015, at 09:33, Matjaz Straus

also , let's not forget the folk using RFC4577 (OSPFv2) because customer wants an OSPF network and needs the providers network to participate in the routing. I have come across some of this stuff , and I would have given it third place, possibly a tie with the folk using iBGP because they either

I'd say static routing for single homed deployments and BGP for dual homed. Anything else only if there's a very specific requirement. Whilst there are other options it doesn't mean you have to use or make all of them available. Keep in mind that someone will have to maintain/support that network.

Depends on your segment. In the larger enterprises many of them run EIGRP and need you to run it, this is (was) a pain as if your edge device wasn't Cisco you ended up having to put a layer of Cisco 26/36 devices to do redistribution. I've seen OSPF plenty of times also. Only one on that list I

Yes we have this scenario also but unfortunately it doesn't cover every use case (esp on fast failover and/or mixed carrier setups). Cheers, Neil Sent from my iPhone On 18 Jun 2015, at 10:01, Alistair C mailto:uk...@imf2000.org>> wrote: On 18 June 2015 at 02:01, Neil J. McRae mailto:n...@dom
