Voice Multicasting over an Ethernet LAN
Figure 134 shows the simplest configuration for voice multicasting over an Ethernet LAN. Two routers
are connected to each other over the Ethernet LAN. One E&M phone is connected to each router.
Figure 134 Voice Multicasting over a LAN
In router Abbott (Figure 134), the phone is connected to voice port 2/0/0, using the
router-slot/voice-slot/VIC-port numbering convention. This router is configured as in the following
example:
hostname Abbott
!
ip multicast-routing
!
voice class permanent 1
signal timing oos timeout disabled
signal keepalive 65535
!
interface Vif1
ip address 1.1.1.1 255.0.0.0
ip pim sparse-dense-mode
!
interface Ethernet0/0
ip address 3.3.3.1 255.0.0.0
ip pim sparse-dense-mode
!
ip route 2.0.0.0 255.0.0.0 3.3.3.2
!
voice-port 2/0/0
voice-class permanent 1
connection trunk 111
operation 4-wire
!
dial-peer voice 1 voip
destination-pattern 111
session protocol multicast
session target ipv4:237.111.0.111:22222
!
Note The connection-trunk connection type is a point-to-point connection, similar to a tie-line on a PBX
network. All voice traffic—including signaling—placed at one end is immediately transferred to the
other.
Note The E&M voice port must be configured for four-wire operation.
