The output shows that Router D has only one route 192.168.64.0/18 to AS 65106.
After the above configurations, ping the hosts on subnets 192.168.64.0/24, 192.168.74.0/24
and 192.168.99.0/24 from Router D. The ping operations succeed.
BGP community configuration
Network requirements
As shown in Figure 77, EBGP runs between Router B and Router A, and between Router B and Router C.
Configure No_Export community attribute on Router A to make routes from AS 10 not advertised by AS
20 to any other AS.
