Configuration
Procedure
You need to enable IP multicast routing features only if network users
require access to IP multicast application traffic from local or remote
sources.
To activate IP multicast routing and filtering capabilities in your system,
follow this general procedure:
1 Configure VLANs and IP routing interfaces on the system. See Chapter 9
for more information about VLANs. See Chapter 11 for more information
about IP routing.
2 Ensure that IGMP snooping and querying functions are enabled on the
system.
For general information about IGMP, see "How IGMP Supports
IP Multicast" earlier in this chapter.
For information about configuring IGMP functions on your system, see
"Configuring IGMP Options" later in this chapter.
3 Enable DVMRP on each interface that is to perform IP multicast routing.
You can modify the default TTL threshold and DVMRP metric values that
the system assigns to each interface.
For general information about DVMRP see "How DVMRP Supports
IP Multicast" earlier in this chapter.
For information about configuring DVMRP, see "Configuring DVMRP
Interfaces" later in this chapter.
4 If your network requires a multicast tunnel and if your system is going to
serve as one or more tunnel endpoints, configure the tunnels now. You
can configure up to 8 tunnels per system. Remember to configure the
tunnels on the remote systems as well.
See "Configuring DVMRP Tunnels" later in this chapter.
5 Configure a default route on an interface (if applicable to your network).
See "Configuring DVMRP Default Routes" later in this chapter.
