Usage Guidelines

Usage Scenario

The display bgp paths command displays the path attributes of BGP stored in the system.

BGP usually has a large number of path attributes. The display bgp paths command displays a lot of BGP path information for viewing. After configuring as-regular-expression, the display bgp paths command displays only the path attributes of BGP that match as-regular-expression. For details on a regular expression, see Filtering Output Information Based on the Regular Expression in "CLI Overview" in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - Basic Configuration.

Precautions

BGP has a number of address families and the path attributes of BGP in each address family is stored independently. By default, the display bgp paths command displays only the path attributes of BGP in the IPv4 unicast address family. The path attributes of BGP in other address families can be displayed by specifying address family parameters.
