PIM Sparse-Mode (PIM-SM) | 677Figure 30-3. Viewing the PIM Multicast Routing TableConfigurable S,G Expiry TimersBy default S, G entries expire in 210 seconds. You can configure a global expiry time (for all (S,G) entries)or configure a expiry time for a particular entry. If both are configured, the ACL supercedes the globalconfiguration for the specified entries.When an expiry time created, deleted, or updated, the changes are applied when the keep alive timerrefreshes.To configure a global expiry time:Configure the expiry time for a particular (S,G) entry:Task Command Command ModeEnable global expiry timer for S, G entriesRange 211-86400 secondsDefault: 210ip pim sparse-modesg-expiry-timer secondsCONFIGURATIONStep Task Command Syntax Command Mode1 Create an Extended ACL ip access-list extended access-list-name CONFIGURATION2 Specify the source and groupto which the timer will beapplied using extended ACLswith permit rules only.[seq sequence-number] permit ipsource-address/mask | any | hostsource-address} {destination-address/mask |any | host destination-address}CONFIG-EXT-NACLFTOS#show ip pim tibPIM Multicast Routing TableFlags: D - Dense, S - Sparse, C - Connected, L - Local, P - Pruned,R - RP-bit set, F - Register flag, T - SPT-bit set, J - Join SPT,Timers: Uptime/ExpiresInterface state: Interface, next-Hop, State/Mode(*, 192.1.2.1), uptime 00:29:36, expires 00:03:26, RP 10.87.2.6, flags: SCJIncoming interface: GigabitEthernet 4/12, RPF neighbor 10.87.3.5Outgoing interface list:GigabitEthernet 4/11GigabitEthernet 7/13(10.87.31.5, 192.1.2.1), uptime 00:01:24, expires 00:02:26, flags: FTIncoming interface: GigabitEthernet 7/11, RPF neighbor 0.0.0.0Outgoing interface list:GigabitEthernet 4/11GigabitEthernet 4/12GigabitEthernet 7/13--More--
