ip multicast dvmrp cacheDisplay 519
inVif Interface that receives incoming IP multicast traffic from
the spanning tree for the source, subnetwork, and group
listed on the left.
The interface is presented as an index number and either
an
I or a T precedes the index number. An I precedes a
routing interface index number. A T precedes a tunnel
index number.
A P after the index number indicates that a prune
message has been sent to an upstream router.
The entry may appear if the system is not able to
build the cache entry correctly. This temporary condition
corrects itself quickly.
outVif Interfaces to which traffic from the inVif is being
forwarded.
Each interface is presented as an index number and either
an
I or a T precedes each index number. An I precedes
a routing interface index number. A T precedes a tunnel
index number.
A p after an index number indicates that the upstream
router has pruned this branch of the delivery tree and no
multicast packets are being forwarded through this local
interface. Eventually this entry disappears from the cache
display.
Either no entry or appears in this column if the
system is not able to build the cache entry correctly. This
temporary condition corrects itself quickly.
Ports Physical ports that correspond to the interfaces that are
listed in the outVifs field. The Ports field shows a dash (--)
when there are no outgoing interfaces and when the
outgoing interfaces are tunnels.
