  1. Indonesian Higher EducationNetwork Backbone

  2. INHERENT Backbone

  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: 167.205.128/18 • /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: 64512 – 65535 • INHERENT Backbone: 65001-650032

  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
