Examples:

In the following example, the Ver/Mode column displays "SD" when configured in Sparse-Dense Mode (SDM).

vyatta@R2:~$ show ip pim interface 
Address          Interface           VIFindex Ver/   Nbr    DR         DR
                                              Mode   Count  Prior
10.0.0.3         dp0s7              1        v2/SD   1      1          10.0.0.3
10.0.2.3         dp0s8              2        v2/SD   0      1          10.0.2.3
10.0.23.3        dp0s9              0        v2/SD   1      1          10.0.23.7
2.2.2.2          lo1                 4        v2/S   0      1          2.2.2.2

In this example, the Mode field shows Sparse-Dense when configured as SDM.

vyatta@R2:~$ show ip pim interface detail
