BGP Configuration Overview
To configure the device as a node in a BGP network:
- Configure network interfaces. See the Junos OS Interfaces Configuration Guide for Security Devices.
- Configure point-to-point peering sessions. See Example: Configuring External BGP Point-to-Point Peer Sessions.
- Configure IBGP sessions between peers. See Example: Configuring Internal BGP Peer Sessions.
- Configure a routing policy to advertise the BGP routes.
- (Optional) Configure route reflector clusters. See Example: Configuring a Route Reflector.
- (Optional) Subdivide autonomous systems (ASs). See Example: Configuring BGP Confederations.
- (Optional) Assign a router ID to each routing device running BGP.
- (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.
- (Optional) Configure routing table path selection options that define different ways to compare multiple exit discriminators (MEDs). See Understanding BGP Path Selection in the Junos OS Routing Protocols Configuration Guide.
