DVMRP
Routing Table
Viewing the
DVMRP Cache
Your system records DVMRP route information in a table that you can
access from the management interface. Your system learns source-based
route information from neighboring DVMRP routers and also advertises
routes that it learns to its neighbors. The routing table does not consider
group membership or prune messages. It simply records path information
it has learned on its own or from other routers, including:
Subnetworks from which IP multicast traffic originates
Upstream routers (gateway) from which the system should expect to
receive traffic from origin subnetworks
Index number of the interface (parent) that is connected to the
upstream router
Outgoing interfaces (children) on which it could forward traffic if
group members exist.
The system may never receive process IP multicast traffic from the sources
listed in the routing table. Receipt of IP multicast traffic depends on
whether group members exist on directly-attached subnetworks or on
subnetworks from downstream routers.
See the Command Reference Guide for definitions of the fields of
information and symbols used in the DVMRP route display.
Your system records information about the IP multicast group traffic it has
processed. You can see this information in the DVMRP cache.
To display the DVMRP cache, the system prompts you to enter:
A multicast source address
A multicast group address
This process limits the cache table to displaying information for one
source-group pair at a time. To display cache information for all
source-group pairs, enter
See the Command Reference Guide for definitions of the fields of
information and symbols used in cache display.
