Example
In the following example, the router is configured to reject routes received
from neighbor 172.20.1.1 with an AS path that indicates the route originates
in or passes through AS 100.

console(config)# ip as-path access-list 1 deny ^100$
console(config)# router bgp 1
console(config-router)# neighbor 172.20.1.1 remote-as 200
console(config-router)# neighbor 172.20.1.1 filter-list 1 in
ip bgp-community new-format

community new-format command. To display BGP standard communities as
32-bit integers, use the no form of this command.

User Guidelines
RFC 1997 specifies that the first two bytes of a community number are
considered to be an autonomous system number. The new format displays a
community number as the ASN followed by a 16-bit AS-specific number.
Example
console(config)#ip bgp-community new-format
