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

[Ankit Agrawal]

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 :)
