• Distribute List - The access list that filters the routes to be redistributed by the destination protocol. Displays 0 when not configured. • Redistribute - Redistribute among other VLANs in the domain. Displaying the Route Redistribution Summary Using CLI Commands For information about the CLI command that performs this function, see the following chapter in the CLI Reference Guide: • OSPF Commands The following table summarizes the equivalent CLI commands for this feature. Table 9-18. OSPF Route Redistribution Summary Command CLI Command show ip ospf Description Displays OSPF route redistribution summary data. BOOTP/DHCP Relay Agent BootP/DHCP Relay Agent enables BootP/DHCP clients and servers to exchange BootP/DHCP messages across different subnets. The relay agent receives the requests from the clients, and checks the valid hops and giaddr fields. If the number of hops is greater than the configured, the agent assumes the packet is looped through the agents and discards the packet. If giaddr field is zero the agent must fill in this field with the IP address of the interface on which the request was received. The agent unicasts the valid packets to the next configured destination. The server responds with a unicast BOOTREPLY addressed to the relay agent closest to the client as indicated by giaddr field. Upon reception of the BOOTREPLY from the server, the agent forwards this reply as broadcast or unicast on the interface form where the BOOTREQUEST was arrived. This interface can be identified by giaddr field. T he PowerConnect 8024/8024F DHCP component also supports DHCP relay agent options to identify the source circuit when customers are connected to the Internet with high-speed modem. The relay agent inserts these options when forwarding the request to the server and removes them when sending the reply to the clients. If an interface has more than one IP address, the relay agent should use the primary IP address configured as its relay agent IP address. The BOOTP/DHCP Relay Agent menu page contains links to web pages that configure and display BOOTP/DHCP relay agent. To display this page, click Routing →BOOTP/DHCP Relay Agent in the tree view. Following are the web pages accessible from this menu page: • BOOTP/DHCP Relay Agent Configuration BOOTP/DHCP Relay Agent Configuration Use the BOOTP/DHCP Relay Agent Configuration page to configure and display a BOOTP/DHCP relay agent. 536 Configuring Routing

Displaying the Route Redistribution Summary Using CLI Commands
For information about the CLI command that performs this function, see the following chapter in the
CLI Reference Guide:
OSPF Commands
The following table summarizes the equivalent CLI commands for this feature.
BOOTP/DHCP Relay Agent
BootP/DHCP Relay Agent enables BootP/DHCP clients and servers to exchange BootP/DHCP messages
across different subnets. The relay agent receives the requests from the clients, and checks the valid hops
and giaddr fields. If the number of hops is greater than the configured, the agent assumes the packet is
looped through the agents and discards the packet. If giaddr field is zero the agent must fill in this field
with the IP address of the interface on which the request was received. The agent unicasts the valid
packets to the next configured destination. The server responds with a unicast BOOTREPLY addressed
to the relay agent closest to the client as indicated by giaddr field. Upon reception of the BOOTREPLY
from the server, the agent forwards this reply as broadcast or unicast on the interface form where the
BOOTREQUEST was arrived. This interface can be identified by giaddr field.
T he PowerConnect 8024/8024F DHCP component also supports DHCP relay agent options to identify
the source circuit when customers are connected to the Internet with high-speed modem. The relay
agent inserts these options when forwarding the request to the server and removes them when sending
the reply to the clients.
If an interface has more than one IP address, the relay agent should use the primary IP address
configured as its relay agent IP address.
The
BOOTP/DHCP Relay Agent
menu page contains links to web pages that configure and display
BOOTP/DHCP relay agent. To display this page, click
