Example of Viewing Configured Prefix Lists (ROUTER OSPF mode)
To view the configuration, use the
show config
command in ROUTER OSPF mode, or the
show running-
config ospf
command in EXEC mode.
Dell(conf-router_ospf)#show config

ACL Resequencing
ACL resequencing allows you to re-number the rules and remarks in an access or prefix list.
The placement of rules within the list is critical because packets are matched against rules in sequential order.
To order new rules using the current numbering scheme, use resequencing whenever there is no
opportunity.
For example, the following table contains some rules that are numbered in increments of 1. You cannot place
new rules between these packets, so apply resequencing to create numbering space, as shown in the second
table. In the same example, apply resequencing if more than two rules must be placed between rules 7 and
10.
You can resequence IPv4 and IPv6 ACLs, prefixes, and MAC ACLs. No CAM writes happen as a result of
resequencing, so there is no packet loss; the behavior is similar Hot-lock ACLs.
NOTE: ACL resequencing does not affect the rules, remarks, or order in which they are applied.
Resequencing merely renumbers the rules so that you can place new rules within the list as needed.
