Syntax: show ip dvmrp [vrf vrf-name] mcache
The vrf option allows you to display DVMRP Multicast cache information for the VRF instance
identified by the vrf-name variable
The display shows the following information
TABLE 26 Output from the show ip dvmrp mcache command
Field Description
Total entries in mcache Shows the total number of PIM mcache entries
Uptime Shows the entry uptime
Rate Shows the Rate at which packets are ingressing for this entry
upstream neighbor Shows the upstream neighbor for the Source/RP based on the type of
entry. For (*,G) it shows the upstream neighbor towards the RP. For (S,G)
entries it shows the upstream neighbor towards the source.
Flags Flags Represent Entry flags in hex format in the braces. And indicates
the meaning of the flags set in abbreviated string whose explanations
are as below. Only shows the flags which are set.
SM - Shows If the entry is created by PIM Sparse Mode
DM - Shows If DM mode entry is enabled
SSM - Shows If the SSM mode entry is enabled
RPT - Shows If the entry is on the Rendezvous Point (RP)
SPT - Shows If the entry is on the source tree
LSRC - Shows If the source is in a directly-connected interface
LRcv - Shows If the receiver is directly connected to the router
REG - if the data registration is in progress
L2REG - if the source is directly connected to the router
REGSUPP - if the register suppression timer is running
RegProbe
HW - Shows If the candidate for hardware forwarding is enabled
FAST - Shows If the resources are allocated for hardware forwarding
TAG - Shows If there is a need for allocating entries from the replication
table
MSDPADV - Shows If RP is responsible for the source and must be
advertised to its peers.
NEEDRTE - Shows If there is no route to the source and RP is available
LEAF - Shows If DVMRP is enabled
PRUNE - Shows If PIM DM Prune to upstream is required
RP Show the IP address of the RP.
fast ports Shows forwarding port mask.
AgeSltMsk Shows the slot number on which MP expects ingress traffic.
FID, MVID Shows the resources that are allocated for forwarding the entry.
RegPkt Shows Count of Packets forwarded due to the Register decapsulation.
