Juniper JUNOSE 11.2.X BGP AND MPLS User Manual

Monitoring BGP Routes with Matching AS Paths and AS-Path Access Lists
Purpose Display all routes whose AS-path matches the specified AS-path access list. Report
whether the indirect next hop of a route is unreachable; if not, display the IGP cost to the
indirect next hop.
The show ip bgp filter-list and show bgp ipv6 filter-list commands display similar
information.
Action To display all routes whose AS-path matches the specified AS-path access list:
