Naming Convention
IP Addressing
Routing Protocol
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
IP Addressing
 Structured IP addressing design to enable IP
address summarization
 Public IP: temporarily using ITB: 167.205.128/18
 /23 for Advanced POPs
 /24 for Medium & Basic POPs
 Address allocation
Links
Loopbacks
Hosts
IP Addressing Example
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
AS Number
Use private AS number for All POPs
Those who has public AS number may use
their AS number
Private AS number: 64512 – 65535
 INHERENT Backbone: 65001-650032
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
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
