Since we're on the topic of IPv6, I wanted to gauge the current attitude of
the ops. community toward its deployment. We're seeing a lot more interest
from our enterprise clients in using v6, especially as things like VoIP and
PDAs consume their address pools, and NAT gets in the way of
This is impressive. It's very nice to see a carrier providing this level of
technical analysis to customers after an outage. Many carriers would be
embaressed or try to gloss over what has happened. Sprintlink, in the old
days, was also very good about this. Customers really appreciate honesty

It depends a lot on your topgraphy. For example, if you have a specific
city/region aggregation center, your redundant boarder routers for that
city are probably also RRs. Those boarders peer with your boarders in
other cities as well as your intra-region routers.

Yup. I like using OSPF to set up the mesh to the loopbacks and then ibgp

Running two routing protocols is too much of a hassle. I think I would
rather use static routes, and synchronize routers using rsync, diff, and
patch. Our NOC has several 286s running Xenix that could act as servers
for this.
This would eliminate the hassle of running OSPF, ISIS, or RIP.

Ralph, they are talking about running BGP as an IGP, not if they are going
to run BGP at all. Most large carriers run BGP everywhere. They also run an
IGP for next-hop reachability within their networks (loopbacks, interface

Ralph,
Okay, no one ever said an IBGP mesh was bad. We were all upset
by the mention of an IGP distributed into an EGP. Let's do a little math
here. The formula for IBGP sessions goes as follows.
n*(n-1)/2
2=1
3=3
4=6
5=10
So you've only got 4 routers? That's fine, 6 sessions is not

Every time you see one of us mention ISIS or OSPF, all it has to do
