Configuring DVMRP
Distance Vector Multicast Routing Protocol is used to route multicast traffic to nodes
which have requested a specific multicast service via IGMP. (See “DVMRP Routing
Protocol” on chapter 4.) To configure DVMRP, you must specify the routing metric,
probe interval, and neighbor router timeout.
Parameter Def ault Description
Metrics 1 hop This value is used to select the best reverse path to networks
that are connected directly to an interface on this switch.
Range: 1-31 hops
Probe
Interval
10
seconds
The interval between sending neighbor probe messages to the
multicast group address for all DVMRP routers.
Range: 5-30 seconds
Neighbor
Timeout
35
seconds
The interval to wait without hearing from a DVMRP neighbor
before declaring it dead. This is used for timing out routes, and
for setting the children and leaf flags.
Range: 10-8000 seconds
Note:
IGMP is automatically enabled / disabled along with DVMRP. (See “IGMP
Protocol” on chapter 4.)
3.6.6.2.Protocol Configuration Use the Protocol Configuration screen to globally enable or disable unicast or multicast
routing protocols for the switch.
Parameter Description
ARP Sets the aging time for dynamic ARP entries.
RIP Sets the interval at which the switch advertises known r outes,
enables or disables advertising the switch as the default router, and
enables or disables advertising static routes.
OSPF Organizes an autonomous system into normal, stub, or not so stubby
areas; configures a range of subnet addresses for which link state
advertisements can be aggregated; and configure virtual links for
areas that do not have direct physical access to the OSFP
backbone, to add redundancy, or to merge backbone areas.
Boot Relay Defines the preferred servers or the outbound subnetworks for
