Configuring mrouted
How to Configure mrouted
Chapter 232
You can use the phyint command to disable multicast routing on the
physical interface identified by the local IP address,
local-addr
(see
Figure 2-1), or to associate a nondefault metric or threshold with the
specified physical interface. Alternatively, you can replace the local IP
address,
local-addr
, with the interface name, such as lan0.Ifphyint is
attached to multiple IP subnets, use the altnet option to describe each
additional subnet (one altnet option for each subnet).
tunnel
You can use the tunnel command to establish a tunnel link between the
local IP address,
local-addr
, and the remote IP address,
remote-addr
(see Figure 2-1). You can also use this command to associate a nondefault
metric or threshold value with the tunnel. You can replace the local IP
address,
local-addr
, with the interface name, such as lan0. Similarly,
you can replace the remote IP address,
remote-addr
, by a host name,
but only if the host name has a single IP address associated with it.
Before you can use a tunnel, it must be set up in the mrouted
configuration files of both the mrouted routers participating in the
tunnel. mrouted 3.8 does not support the srcrt option. (It provided
backward compatibility with older versions of mrouted that implemented
IP multicast datagram encapsulation using IP source routing.)
