[j-nsp] Filter odd and even ip address in JUNOS

[Kae Hsu]

I got the answer from user guide,
It is allowed to use wildcard bits style address in filter filter:

{master}[edit firewall family inet filter test]
cn at LAB-M40e# show
/* Filter source IP address with odd host number in 192.168.10.0/24 */
term 1 {
     from {
         source-address {
             192.168.10.1/0.0.0.254;
         }
     }
}
/* Filter source IP address with even host number in 192.168.10.0/24 */
term 2 {
     from {
         source-address {
             192.168.10.0/0.0.0.254;
         }
     }
}

{master}[edit firewall family inet filter test]
cn at LAB-M40e#
