Configuring IP Interfaces and Parameters
96 Enterasys Xpedition User Reference Manual
Border Gateway Protocol (BGP) Version 3, 4 (RFC 1267, 1771). Configuring BGP for the
XP is described in Chapter 14.
Multicast Routing Protocols
IP multicasting allows a host to send traffic to a subset of all hosts. These hosts subscribe
to group membership, thus notifying the XP of participation in a multicast transmission.
Multicast routing protocols are used to determine which routers have directly attached
hosts, as specified by IGMP, that have membership to a multicast session. Once host
memberships are determined, routers use multicast routing protocols, such as DVMRP, to
forward multicast traffic between routers.
The XP supports the following multicast routing protocols:
Distance Vector Multicast Routing Protocol (DVMRP) RFC 1075
Internet Group Management Protocol (IGMP) as described in RFC 2236
The XP also supports the latest DVMRP Version 3.0 draft specification, which includes
mtrace, Generation ID and Pruning/Grafting. Configuring multicast routing for the XP is
described in Chapter 16.
Configuring IP Interfaces and Parameters
You can configure an IP interface to a single port or to a VLAN. This section provides an
overview of configuring IP interfaces.
Interfaces on the XP are logical interfaces. Therefore, you can associate an interface with a
single port or with multiple ports:
To associate an interface with a single port, use the port option with the
interface create command.
To associate an interface with multiple ports, first create an IP VLAN and add ports to
it, then use the vlan option with the interface create command.
The interface create ip command creates and configures an IP interface. Configuration of
an IP interface can include information such as the interfaces name, IP address, netmask,
broadcast address, and so on. You can also create an interface in a disabled (down) state
instead of the default enabled (up) state.
Note: You must use either the port option or the vlan option with the interface create
command.
