2. Select the route redistribution entry that you want to delete.
3. Click Delete.
CLI Commands To delete an IP redistribute list entry, use the following CLI commands:
■ To delete an entry that redistributes routes to RIP, (configure
router:rip)
no redistribute {ospf | local | static}
■ To delete an entry that redistributes routes to OSPF, (configure
router:ospf)
no redistribute {rip | local | static}
IP Multicast
IP Multicast enables a single host to distribute information to multiple
recipients. To do this, multicast protocols use class D IP addresses to
specify specific multicast groups to which information is sent. The class D
IP address used by multicast routing protocols, ranges from 224.0.0.1 to
224.0.0.255. The class D IP addresses available for general use are
224.0.1.0 to 239.255.255.255.
In addition, IP multicasting distributes information to multicast groups in
two specific ways:
■ Multicast Forwarding - allows a switch to forward multicast
traffic from the local multicast server to group members on directly
attached subnetworks. If a multicast packet is forwarded to multiple
interfaces on one VLAN, only one Forwarding Entry is added on the
VLAN for the packet. One copy of the packet is sent to the VLAN.
To configure interfaces for multicast forwarding select Internet
Group Management Protocol (IGMP) for the multicast protocol.
* Note: Interfaces configured for IGMP forwarding will not be able to
participate in multicast sessions distributed through DVMRP
Routing.
■ Multicast Routing - allows a switch to deliver multicast traffic
between neighboring routers and across the network using Distance
Vector Multicast Routing Protocol (DVMRP).To configure
interfaces for multicast routing select DVMRP for multicast
protocol on all interfaces that are part of a multicast network.Since
IGMP is required on all interfaces that have multicast clients, IGMP
is enabled automatically on all interfaces configured for DVMRP.
* Note: You must globally enable IP multicast routing in order to
successfully configure IGMP or DVMRP. See “Routing
Function” earlier in this chapter for instructions on enabling IP
multicast routing.
