Hi,=20
After recent discussions on the list, I've been thinking about the affects
of multiple BGP feeds to the overall resilience of Internet connectivity
for my organisation.=C2=A0 So originally when I looked at the design
proposals, there was a provision in there for four connections with the
same Internet provider.=C2=A0 Thinking about it and with the valuable input=
of
members on this list, it was obvious that multiple connections from the
same provider defeated the aim of providing resilience.=20
So having come to the decision to use two providers and BGP peer with
both, I'm wondering how much more resilience I would get by peering
with=C2=A0more than two=C2=A0providers.=C2=A0 So will it significantly incr=
ease my
resilience by peering with three providers for example, as both of the
upstreams I choose will be multihomed to other providers.=C2=A0 Especially =
as
I am only looking at peering out of the UK.=20
Hope the above makes sense.=20
