• Fragments
• DSCP field
Note:
The fragment criteria is used for non-initial fragments only. You cannot specify TCP/UDP
ports or ICMP code/type for a rule when using the
fragment
command.
Use IP wildcards to specify a range of source or destination IP addresses. The zero bits in the
wildcard correspond to bits in the IP address that remain fixed. The one bits in the wildcard
correspond to bits in the IP address that can vary. Note that this is the opposite of how bits are
used in a subnet mask.
Note:
When you use destination and source ports in a PBR rule, policy-based routing does not
catch fragments.
Note:
It is recommended to leave a gap between rule numbers, in order to leave room for inserting
additional rules at a later time. For example, ip-rule 10, ip-rule 20, ip-rule 30.
