With the support of AS range filtering, we need to print the configuration
accordingly.
Before :
# bgpd -dnv
[...]
deny from any AS 0
deny from any AS 0
deny from any AS 65535
deny from any AS 0
deny from any AS 0
deny from any AS 0
deny from any AS 4294967295
After :
# bgpd -dnv
[...]
deny from any AS 64496 - 64496
deny from any AS 64512 - 64512
deny from any AS 65535
deny from any AS 65536 - 65536
deny from any AS 65552 - 65552
deny from any AS 4200000000 - 4200000000
deny from any AS 4294967295
