(<source>, <group>) The comma-separated values in parentheses is a source-group pair.
The <source> is the PIM source for the multicast <group>. For example, the following entry
means source 209.157.24.162 for group 239.255.162.1:
(209.157.24.162,239.255.162.1)
If the <source> value is * (asterisk), this cache entry uses the RP path. The * value means
“all sources”.
If the <source> is a specific source address, this cache entry uses the SPT path.
RP<ip-addr> Indicates the RP for the group for this cache entry.
NOTE: The RP address appears only if the RPT flag is set to 1 and the SPT flag is set to 0
(see below).
forward port The port through which the Layer 3 Switch reaches the source.
Count The number of packets forwarded using this cache entry.
Sparse Mode Indicates whether the cache entry is for regular PIM (dense mode) or PIM Sparse. This flag
can have one of the following values:
• 0 – The entry is not for PIM Sparse (and is therefore for the dense mode of PIM).
• 1– The entry is for PIM Sparse.
