INHERENT Backbone

Layer 3 Network Design 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
