Configuring IP Multicasting
7-17
Parameter: Garbage Timeout
Default: 340 seconds
Range: 40 to 8000 seconds
Function: Specifies, in seconds, the duration of time that this route will be included
in routing updates without the receipt of a subsequent update indicating
that the route is reachable.
The difference between this value and the Route Expiration Timeout
value represents the duration of time that the route will be advertised as
unreachable without subsequent refreshment.
Instructions: Enter a value that is greater than the value you specified for Route
Expiration Timeout to allow for sufficient time for the route to be
advertised as unreachable.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.12.1.9
Parameter: Estimated Routes
Default: 25 routes
Range: An integer of 10 or greater
Function: Specifies the estimated number of routes.
Instructions: Enter a value that the router can use for preallocating routing tables. For
an MBone deployment, a value of 3000 or higher is recommended.
Note that routes are kept on a per-source-network basis, independent of
multicast groups. This number must include a route for every network that
is local to a circuit configured for multicasting. This is to allow the router
to utilize memory efficiently; exceeding this size during router operation
will not cause an error but may cause the router to consume more memory
than is required.
