xStack® DGS-3620 Series Layer 3 Managed Stackable Gigabit Switch CLI Reference Guide DGS-3620-28SC:admin# create ip prefix_list 1 Command: create ip prefix_list 1 Success. DGS-3620-28SC:admin# 42-2 config ip prefix_list Description This command defines the rule entry for an IP route prefix list. A prefix list can have multiple rule entries; each is represented by a sequence number. The rule with the lower sequence number will be evaluated first. If the sequence number is not specified for the defined rule entry, the sequence number will be automatically given. The automatically given sequence number will be a multiple of 5. Therefore, if the defined rule is the first rule in the prefix list, the automatically given sequence number will be 5. If the defined rule is not the first rule in the prefix list, the sequence number will be the number that is a multiple of 5 and larger than the largest sequence number of an existing rule in the prefix list. A prefix list consists of an IP address and a bit mask. The bit mask is entered as a number from 1 to 32. An implicit denial is applied to traffic that does not match any prefix list entry. The IP route prefix list rule entry is defined to either permit or deny specific routes. Prefix lists are configured to match an exact prefix length or a prefix range. The prefix list is processed using an exact match when neither the ge nor le keyword is entered. If only the ge value is entered, the range is the value entered for the ge ge-length argument to a full 32-bit length. If only the le value is entered, the range is from the value entered for the network/length argument to the le le-length argument. If both the ge ge-length and le le-length keywords and arguments are entered, the range falls between the values used for the ge-length and le-length arguments. The following formula is a restriction for the specified ge-length and le-length. network/length < ge ge-length < le le-length
