3. Layer 3 Network Design Naming Convention IP Addressing
Routing Protocol

4. Naming Convention IBRX..Xyy & IBSX..Xyy
IBR/S: INHERENT Backbone Router/Switch
X..X: University/location nickname where device located
E.g.: IBRDIKTI01 & IBSDIKTI01
IDRX..Xyy, IDSX..Xyy, IARX..Xyy & IASX..Xyy
D: Distribution
A: Access
FQDN for INHERENT

5. IP Addressing
Structured IP addressing design to enable IP address summarization
Public IP: temporarily using ITB: /18
/23 for Advanced POPs
/24 for Medium & Basic POPs
Address allocation
Links
Loopbacks
Hosts

6. IP Addressing Example

7. Routing Protocol De-centralized Management
All 32 POPs will be independent
Each University has an equal authority
Each of 32 routers uses its own AS number
Routing:
EBGP
OSPF for WAN links & Loopback only

8. AS Number Use private AS number for All POPs
Those who has public AS number may use their AS number
Private AS number: – 65535
INHERENT Backbone:

9. BGP Policies
Each University must only advertise its own public IPs into INHERENT
Each University must only except other universities public IPs from INHERENT
Each University must set BGP Policy to choose INHERENT for traffic between universities
Weight
Local Preference

10. BGP Policies, Cont.
Each University must not advertise other universities public IPs to the internet
Universities use his own AS number must aware to remove the private AS number when advertise routing to Internet
Inside INHERENT let normal BGP process choose the path
