[AusNOG] powerful routers in core/edge routing/switching

[McDonald Richards]

You're right – some times it's not enough, but I don't think that is the case for the majority of people who are carrying a full BGP table. If you can afford all that connectivity and caching, you can probably afford to buy a router that is suitable to support it all (provided all the afore mentioned caching and connectivity is actually a requirement of the business).

Sometimes default route is not enough and you do need to be aware of full routing table, including local peering to have optimum routing both from cost and user experience perspective. This is especially the case when you are not running a single IP feed from one or two providers but infact have several transit links and peering/caching services.

Of course there are ways to overcome these issues, but then as you said, you end up in a web of network that only you can understand and support and its beyond documentation.

What has port density, capacity or throughput got to do with routing?

Why do people with networks in a single geographic region, even if multi-homed, need to run default-fee? You know you can use a default route and a routing subset to achieve both redundancy and faster convergence?

I'm pretty happy with the current generation of hardware and where it sits price-wise. There have been a lot of good suggestions in the thread so I won't throw anymore in.There are cheaper and smarter ways to do things, but with smarts comes the risk that nobody else can support your tangled web of network magic.

The problem is routing has lagged far behind switching in terms of port density, capacity, throughput etc. Obviously a switching engine is peanuts compared to a routing engine, but it is exaggerated by the massive amounts of features they put in routing engines.

Seems to me we almost need a new breed of edge routers, ones that just talk BGP to other providers, and the current edge can stay as they are handling fancy things like MPLS which is really more of an internal routing, therefore switching, feature. Or not :)
