Enable PIM Neighbor Recognition

Enable PIM in the switches so they exchange the PIM hello message and become neighbors with other switches.

This example enables PIM in SEFOS1 and SEFOS2.

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 in the first switch (in this example, SEFOS 1).

   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. Enable the interconnect between the switches.

   SEFOS(config)# interface extreme-ethernet 0/3
   SEFOS(config-if)# no shut
   SEFOS(config-if)# exit
   

6. Associate the VLAN interface with the PIM component in the second switch (in this example, SEFOS 2).

   SEFOS# configure terminal
   SEFOS(config)# set ip pim enable
   SEFOS(config)# interface vlan 5
   SEFOS(config-if)# ip pim componentId 1
   

7. Specify how often (in seconds) PIM messages are sent on the interface.

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

8. Enable the interconnect between the two switches.

   SEFOS(config)# interface extreme-ethernet 0/3
   SEFOS(config-if)# no shut
   SEFOS(config-if)# exit
   SEFOS(config) #
   

9. View the neighbor.

   In SEFOS1:

   SEFOS# show ip pim neighbor 
    
   Neighbour      IfName/Idx Uptime/Expiry Ver DRPri   CompId 
   Address                                                    
   ---------      ---------- ------------- --- -----   ------ 
   10.1.0.2       Vlan5/33   00:00:19/84    v2    1      1        
    
   SEFOS# show ip pim neighbor vlan 5
    
   Neighbour      IfName/Idx Uptime/Expiry Ver DRPri   CompId 
   Address                                                    
   ---------      ---------- ------------- --- -----   ------ 
   10.1.0.2       Vlan5/33   00:00:19/84    v2    1      1 
   

   In SEFOS2:

   SEFOS# show ip pim neighbor 
    
   Neighbour      IfName/Idx Uptime/Expiry Ver DRPri   CompId 
   Address                         
   ---------      ---------- ------------- --- -----   ------ 
   10.1.0.1       Vlan5/33   00:00:19/84   v2    1     1        
    
   SEFOS# show ip pim neighbor vlan 5
    
   Neighbour      IfName/Idx Uptime/Expiry Ver DRPri   CompId 
   Address                                                    
   ---------      ---------- ------------- --- -----   ------
