Configuring interVLAN routing on the Catalyst 4224 is identical to configuring
interVLAN routing on the Catalyst 6000 with an MSFC. Configuring an interface
for WAN routing is consistent with other Cisco IOS platforms. The following
sample shows a configuration for interVLAN routing.
interface Vlan 160
description Voice VLAN
ip address 10.6.1.1 255.255.255.0
interface Vlan 60
description Data VLAN
ip address 10.60.1.1 255.255.255.0
interface Serial1/0
ip address 160.3.1.2 255.255.255.0
The Catalyst 4224 supports standard IGP routing protocols such as RIP, Interior
Gateway Routing Protocol (IGRP), Enhanced Interior Gateway Routing Protocol
(EIGRP), and open shortest path first (OSPF). It also supports multicast routing
for PIM dense mode, sparse mode, and sparse-dense mode.
In a centralized Cisco CallManager deployment model, the DHCP server would
probably be located across the WAN link. You should include an ip helper
command on the voice VLAN interface that points to the DHCP server so that the
IP phone can obtain the IP address and the TFTP server address. The following
sample configuration shows a configuration for ip helper-address on the voice
VLAN:
interface Vlan 160
description Voice VLAN
ip address 10.6.1.1 255.255.255.0
ip helper-address 172.20.73.14
As an alternative, you could use the Cisco IOS DHCP server capabilities on the
Catalyst 4224. The following sample configuration shows a configuration for the
DHCP configuration options.
C4224_SF(config)# ip dhcp pool SF
C4224_SF(dhcp-config)# ?
