Display PIM Multicast Information

You can view the component ID, the multicast group address used by the listed RP, the network address for the source of the multicast routing information, and a summary of the mroute information.

1. Enable PIM globally.

   SEFOS# configure terminal
   SEFOS(config)# set ip pim enable
   

2. Enter Interface Configuration mode for the interface.

   SEFOS(config)# interface vlan 5
   

3. Associate the VLAN interface with the PIM component.

   SEFOS(config-if)# ip pim componentId 1
   

4. Specify how often (in seconds) the switch sends PIM messages to the interface.

   SEFOS(config-if)# ip pim query-interval 60
   SEFOS(config-if)# exit
   SEFOS(config)#
   

5. Set the RP by either selecting the RP with BSR, or by enabling a static RP.
   • To enable RP using BSR:
     1. Configure the BSR.

        SEFOS(config)# interface vlan 5
        SEFOS(config-if)# ip pim bsr-candidate 30
        SEFOS(config-if)# exit
        

     2. Configure the rp-candidate.

        SEFOS(config)# ip pim component 1
        SEFOS(pim-comp)# rp-candidate holdtime 30
        SEFOS(pim-comp)# rp-candidate rp-address 224.1.0.0 255.255.0.0 	10.1.0.1
        SEFOS(pim-comp)# exit
        

   • Alternatively, to enable static RP, use these steps:
     1. Enable static-rp.

        SEFOS(config)# interface vlan 5
        SEFOS(config)# set ip pim static-rp enable
        SEFOS(config)# ip pim component 1
        

     2. Configure the PIM component and the RP information.

        SEFOS(config)# ip pim component 1
        SEFOS(pim-comp)# rp-static rp-address 224.1.0.0 255.255.0.0 10.1.0.1
        SEFOS(pim-comp)# exit
        

6. Enable IGMP.

   SEFOS(config)# set ip igmp enable
   SEFOS(config)# interface vlan 5
   SEFOS(config-if)# set ip igmp enable
   SEFOS(config-if)# end
   

   Send the IGMP v2 report with a source IP of 10.1.0.10.

7. View the mroute table.

   SEFOS# show ip pim mroute
    
   IP Multicast Routing Table
   --------------------------
   Route Flags S: SPT Bit W: Wild Card Bit R: RPT Bit
   Timers: Uptime/Expires
   Interface State: Interface, State/Mode
    
   PIM Multicast Routing Table For Component 1
   (*, 224.1.0.0) ,00:03:53/--- ,RP : 10.1.0.1
     Incoming Interface : Vlan5 ,RPF nbr : NULL ,Route Flags : WR
     Outgoing InterfaceList :
       Vlan5, Forwarding/Sparse ,00:03:53/---
   

   Alternatively, you can view the mroute table for specific component.

   SEFOS# show ip pim mroute 1 summary

     Outgoing InterfaceList :
       Vlan5, Forwarding/Sparse ,00:03:53/---
   

   Or, you can also view the mroute table for a specific group.

   SEFOS# show ip pim mroute 224.1.0.0 summary

8. Send the multicast data on VLAN 2 to populate the (S,G) entry.
