  Subject: Hub Paradise Project - General Deployment


  Hi:

  The following is another in a series of new initiatives by the UEN =
Engineering and Operations Departments to standardize our router =
configurations and enhance system performance.  The information below =
was provided during the "Hub Paradise" trial in the USU Hub area by Pete =
Kruckenberg and has been adapted for this general deployment =
announcement... =20

  The next installment of the UEN Hub Paradise project will start =
Tuesday August 7, 2001 at 6:00PM (detailed schedule is included below). =
There is a potential it will break some sites or groups of users.  I =
realize that is short notice, but we would like to squeeze this change =
in before school starts.=20

  In this pilot, we will be using some of the capabilities we have now =
that we are a classless IP network. This means we can reduce route table =
sizes by aggregating multiple route announcements into a single "super =
announcement".

  This focus of this initiative will be on reducing route table sizes at =
the edge devices, at the hub, and from the hub to the UEN core. In the =
USU pilot conducted earlier this week Pete projected a 60-95% reduction =
in the size of routing tables at the edge.  The measured benefit after =
the changes were implemented was a reduction in routing table size of =
approx. 90% (from 155 to 13 routes).  With smaller routing tables, this =
will also reduce router memory requirements.

  From the hub to the edge devices, we will be limiting routes sent to =
just the 'default' routes. We will also be removing the 'ip =
default-network' statement from the router, as the default network is =
already tagged in the routing protocol and the configuration command is =
unnecessary. This will not interfere with intra-district routing or =
district/hub redundancy routing (in fact, it'll make it easier to do).

  While we have spent an inordinate amount of time checking and =
re-checking our planned changes, it is possible that we might mess =
something up on this test. That's why we're starting at 6:00PM, to give =
plenty of time to check connectivity after the changes are made. And, as =
usual, we will be available Tuesday to work on specific problems that =
might crop up or after hours on the NOC on-call pager.

  Possible problems would present themselves in an entire site or an =
entire block of servers/users (within the same address block) not being =
able to get to the Internet or UEN services, or be reachable from the =
Internet and UEN. Problems should be very obvious (which is good and =
bad).

  When problems are reported, we need to know the IP addresses of the =
user and the site they are trying to reach to diagnose the problem. =
Report all problems to the NOC at 801-585-7440.

  All changes should be complete by 10:00PM, if you'd like to get a =
head-start on checking things before the start of business the following =
day. If there are specific checks you would like us to run, send me an =
email with a list of the sites and services and we will check them for =
you. We will on a district-by-district basis following the =
implementation of these changes report on the impact to sites within =
each district we used as performance benchmarks.  If you would like us =
to evaulate the impact on a speecific site within your district, please =
forward that information to me.

  There are no specific changes necessary for you to make on elementary =
school routers.

  General Deployment Schedule:
  Dixie/NUES/CEU - Tuesday August 7th
  DATC/UVSC - Wednesday August 8th
  SLCC - Thursday August 9th
  SUU/Snow/Snow South - Friday August 10th
  San Juan/Moab/Roosevelt - Monday August 13th

  6:00 P.M. Apply distribute list changes to core and hub devices
  3:00 A.M the following day CiscoWorks will apply the following =
clean-up changes to edge devices in the respective hub area and =
exceptions cleaned up manually by 9:00 a.m.

  Router Clean-up Changes:
  Security issues:
   no service udp-small-servers
   no service tcp-small-servers
   no ip http server
   no ip finger

  Network:
   no ip default-network 205.124.253.0
   (some default-networks are different IP's, and will have to
   be cleaned up manually)

   router eigrp 205
    no auto-summary

  As always, call me or email with your questions or concerns.
