Example: Configuring BGP for CLNS VPNs
This example shows how to create a BGP group for CLNS VPNs, define the BGP peer neighbor address for the group, and define the family.
Requirements
Before you begin, configure the network interfaces.
See the Junos OS Interfaces Configuration Guide for Security Devices 
.
Overview
In this example, you create the BGP group called pedge-pedge, define the BGP peer neighbor address for the group as 10.255.245.215, and define the BGP family.
Configuration
CLI Quick Configuration
To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, and then copy and paste the commands into the CLI at the [edit] hierarchy level.
Step-by-Step Procedure
The following example requires you to navigate various
levels in the configuration hierarchy. For information about navigating
the CLI, see Using the CLI Editor in Configuration Mode in the Junos OS CLI User Guide .
To configure BGP for CLNS VPNs:
- Configure the BGP group and define the BGP peer neighbor
address.[edit protocols bgp]user@host# set group pedge-pedge neighbor 10.255.245.213
- Define the family.[edit protocols bgp]user@host# set family iso-vpn unicast
- If you are done configuring the device, commit the configuration.[edit]user@host# commit
Verification
Confirm that the configuration is working properly.
Verifying the Neighbor Status
Purpose
Display information about the BGP peer.
Action
From operational mode, run the show bgp neighbor 10.255.245.213 command. Look for iso-vpn-unicast in the output.
