How to Conﬁgure mrouted

When the mrouted daemon starts, it automatically reads the default conﬁguration ﬁle /etc/mrouted.conf. You can override the default conﬁguration ﬁle by specifying an alternate ﬁle while invoking mrouted. See “Starting mrouted” on page 36 for more information. If you change the /etc/mrouted.conf ﬁle while mrouted is running, issue the following command to reread the conﬁguration ﬁle:

kill -HUP

By default, mrouted automatically conﬁgures itself to forward on all multicast-capable interfaces, excluding the loopback interface that has the IFF_MULTICAST ﬂag set. Therefore, you do not need to explicitly conﬁgure mrouted, unless you need to conﬁgure tunnel links, change the default operating parameters, or disable multicast routing over a speciﬁc physical interface.

Conﬁguration Commands

You can deﬁne the conﬁguration commands in the /etc/mrouted.conf conﬁguration ﬁle. mrouted supports ﬁve conﬁguration commands: phyint, tunnel, cache_lifetime, pruning, and name. One or more options are associated with each command.

The syntax of each command is as follows:

phyint local-addr[disable] [metric m] [threshold t] [rate_lim it b]

[boundary (boundary-namescoped-addr/mask-len)] [altnet network/mask-len]

tunnel local-addrremote-addr[metric m] [threshold t] [rate_l imit b]

[boundary (boundary-namescoped-addr/mask-len)]

cache_lifetime ct

pruning off/on

name boundary-name scoped-addr/mask-len
