BGP Configuration Overview

To configure the device as a node in a BGP network:

  1. Configure network interfaces. See the Junos OS Interfaces Configuration Guide for Security Devices PDF Document.
  2. Configure point-to-point peering sessions. See Example: Configuring External BGP Point-to-Point Peer Sessions.
  3. Configure IBGP sessions between peers. See Example: Configuring Internal BGP Peer Sessions.
  4. Configure a routing policy to advertise the BGP routes.
  5. (Optional) Configure route reflector clusters. See Example: Configuring a Route Reflector.
  6. (Optional) Subdivide autonomous systems (ASs). See Example: Configuring BGP Confederations.
  7. (Optional) Assign a router ID to each routing device running BGP.
  8. (Optional) Configure a local preference to direct all outbound AS traffic to a specific peer. See Example: Configuring the Local Preference Value for BGP Routes in the Junos OS Routing Protocols Configuration Guide PDF Document.
  9. (Optional) Configure routing table path selection options that define different ways to compare multiple exit discriminators (MEDs). See Configuring Routing Table Path Selection for BGP in the Junos OS Routing Protocols Configuration Guide PDF Document.
