Configuration Examples

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.

In router Abbott (Figure 134), the phone is connected to voice port 2/0/0, using the router-slot/voice-slot/VIC-portnumbering 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.
