IP Access Control Lists (ACL), Prefix Lists, and Route-maps | 157Figure 8-17. Command Example: show config in the ROUTER RIP ModeTo apply a filter to routes in OSPF, use either of the following commands in the ROUTER OSPF mode:To view the configuration, use the show config command in the ROUTER OSPF mode (Figure 241) or theshow running-config ospf command in the EXEC mode.Figure 8-18. Command Example: show config in ROUTER OSPF ModeACL ResequencingResequencing an ACL or Prefix List is supported on platform eACL Resequencing allows you to re-number the rules and remarks in an access or prefix list. Theplacement of rules within the list is critical because packets are matched against rules in sequential order.Use Resequencing whenever there is no longer an opportunity to order new rules as desired using currentnumbering scheme.For example, Table 8-3 contains some rules that are numbered in increments of 1. No new rules can beplaced between these, so apply resequencing to create numbering space, as shown in Table 8-4. In thesame example, apply resequencing if more than two rules must be placed between rules 7 and 10.Command Syntax Command Mode Purposerouter ospf CONFIGURATION Enter OSPF modedistribute-list prefix-list-name in[interface]CONFIG-ROUTER-OSPF Apply a configured prefix list to incomingroutes.
