Step 7: Log the BGP, IS-IS, and OSPF Adjacency Information

Purpose

The following commands log useful information about Border Gateway Protocol (BGP), Intermediate System-to-Intermediate System (IS-IS), and Open Shortest Path First (OSPF) protocols. If you have other protocols installed, such as Multiprotocol Label Switching (MPLS), Resource Reservation Protocol (RSVP), or Protocol Independent Multicast (PIM), you also might log summary information for them.

Action

To log the protocol peer information, use the following JUNOS CLI operational mode commands:

user@host> show bgp summary | save filename 

user@host> show isis adjacency brief | save filename 

user@host> show ospf neighbor brief | save filename 

Sample Output 1

user@host> show bgp summary | save test

Wrote 45 lines of output to 'test'

user@host> show bgp summary
