SIP User's Manual 10. Network
Each interface must have its own address space. Two interfaces may not share the same
address space, or even part of it. The IP address should be configured as a dotted-decimal
notation.
For IPv4 interfaces, the prefix length values range from 0 to 30.
OAMP Interface Address when Booting using BootP/DHCP: When booting using
BootP/DHCP protocols, an IP address is obtained from the server. This address is used as
the OAMP address for this session, overriding the address configured using the Multiple
Interface table. The address specified for OAMP applications in the table becomes
available when booting from flash again. This allows the device to operate with a temporary
address for initial management and configuration while retaining the address to be used for
deployment.
10.3.1.1.2.2 Gateway Column
This column defines a default gateway for each interface. A default gateway can be defined
for each interface. When traffic is sent from this interface to an unknown destination (i.e.,
not in the same subnet and not defined for any static routing rule), it is forwarded to this
default gateway. The default gateway's address must be on the same subnet as the
interface address. A separate routing table allows configuring additional static routing rules.
See 'Configuring the IP Routing Table on page 118 for more details.
Note: In the example below, the default gateway (200.200.85.1) is available for the
applications allowed on that Interface #1. Outgoing management traffic
(originating on Interface #0) is never directed to this default gateway.

A separate routing table allows configuring static routing rules. Configuring the following
routing enables OAMP applications to access peers on subnet 17.17.0.0 through the
gateway 192.168.0.1.

10.3.1.1.2.3 VLAN ID Column
This column defines the VLAN ID for each interface. This column must hold a unique value
for each interface of the same address family.
