Usage guidelines
When you execute the display bgp routing-table flap-info ipv4 unicast command:
• If the network-address, mask, and mask-length arguments are not specified, the command displays
flap statistics of all BGP IPv4 unicast routes for the public network or the specified VPN.
• If only the network-address argument is specified, the system ANDs the network address with the
mask of a route. If the result matches the network address of the route, the command displays flap
statistics of the route.
