To view the total number of COMMUNITY attributes found, use the show ip bgp summary command.
The text line above the route table states the number of COMMUNITY attributes found.
The show ip bgp community command without any parameters lists BGP routes with at least one

The following describes the show ip bgp community command shown in the following example.
Field Description
Network Displays the destination network prefix of each BGP route.
Next Hop Displays the next hop address of the BGP router. If 0.0.0.0 is listed in this column,

LocPrf Displays the BGP LOCAL_PREF attribute for the route.
Weight Displays the route’s weight.
Path Lists all the ASs the route passed through to reach the destination network.
