1. A Campus Design Example Agricultural University IP design - 2001
Supported protocols – IPV4, IPV6
Intranet – No
Internal is modeled after Internet
which scales.

3. Clean API
Who owns what and who is responsible
Topology
Simple, easy to maintain even in
daytime, redundant if possible
Economy
Expand when there is need or a
good opportunity
Standard
Design based on standards. Benefit
from market competion. Avoid
propitary solutions. Make this more
than words

4. Routing.
BGP4 peering with ISP's
OSPFV2 internal
Router discovery with servers, hosts
OSPFV3 (IPv6)
Strategi
IP-numbers, AS-numbers
Address map
LIR?
Net security
Distributed. Only few central filters

5. Local peering
With other University and companies.
Local cooperation.
Host. Moving all towards DHCP
Collaboration,
Own planning, own staff is running the network
Own competence – No consultants
