IES-1248-51V User’s Guide
453
A domain represents an ISP. Each domain is defined by (and dominates) the VLAN
that are in it and has its own routing table and ARP table. As a result, two or more
VLANs in different domains can use the same IP subnet, and one network can
support multiple ISPs.
VLANs in IP bridges are exclusive. They can be in at most one domain. In addition,
VLANs in IP bridges share the same VLAN space as regular VLANs, so VLANs in IP
bridges must have different VLAN IDs than regular VLANs.
Table 174 IP Bridge Domain Commands
COMMAND DESCRIPTION P
adsl ipbpvc domain set
<domain-name>
Creates the domain with the specified name. H/H
adsl ipbpvc domain show
[<domain-name>]
Displays the settings for the specified domain and the
VLAN that are in the domain.
M/L
adsl ipbpvc domain delete
<domain-name>
Deletes the specified domain. You have to remove the
VLAN that are in the domain first.
H/H
adsl ipbpvc domain dhcpvlan
enable <domain-name> <vlan-
id>
This setting has no effect on DHCP packets that come from
VLANs where the IES-1248-51V’s DHCP relay settings are
active. (See Chapter 54 on page 393. The DHCP relay
settings take precedence over the IP bridge DHCP VLAN
setting.)
This command specifies the VLAN where the domain’s
DHCP server is located. The VLAN must already be in the
domain. The IES-1248-51V forwards subscribers’ DHCP
packets to the selected VLAN and changes the source MAC
address to the IES-1248-51V’s MAC address.
The IES-1248-51V still adds whatever Option 82
information is specified for the VLAN in the DHCP relay
settings. (See Chapter 54 on page 393.)
