Configuring mrouted

A

phyint

 command must precede a

tunnel

 command. All the

phyint

and

tunnel

 command options must be placed on a single line except for

the

boundary

 and

altnet

 options, which can begin on a separate line.

The

metric

is the cost, or overhead, associated with sending a datagram

on the given interface or tunnel, and is used primarily to influence the
choice of routes over which the datagram is forwarded; the larger the
value, the higher the cost. You must keep metrics as small as possible,
because

mrouted

cannot route along paths with metrics greater than 31.

In general, use a

metric

 value of 1 for all links unless you are

specifically attempting to force traffic to take another route. In this case,
the metric of the alternate path should be the sum of the metrics on the
primary path + 1. The default

metric

 value is 1.

The

threshold

 is the minimum IP time-to-live (TTL) required for a

multicast datagram to be forwarded to a given interface or tunnel. It
controls the scope of multicast datagrams. If the TTL value in the
datagram is less than the

threshold

 value, the datagram is dropped; if

the TTL is greater than or equal to the

threshold

 value, the packet is

forwarded. The default

threshold

 value is 1.
