Volume 4-Layer 3 Configurations / Chapter 30-Border Gateway Protocol (BGP) Available Customizing Options for BGP Peers BGP Configuration commands Command no bgp default ipv4-unicast neighbor {IP-ADDRESS | PEER-GROUP-NAME} remote-as AS-NUMBER neighbor {IP-ADDRESS | PEER-GROUP-NAME} description TEXT address-family ipv4 [unicast] neighbor {IP-ADDRESS | PEER-GROUP-NAME} route-map MAP-NAME {in|out} neighbor {IP-ADDRESS | PEER-GROUP-NAME} advertisement-interval SECONDS neighbor {IP-ADDRESS | PEER-GROUP-NAME} shutdown Explanation the bgp default command enables the IP version 4 (IPv4) unicast address family for all neighbors. This affects the BGP global configuration. The no form of the command to disable this function. Use this command to add an entry to the Border Gateway Protocol (BGP) neighbor table. Use the no form of this command to remove an entry from the table. Use this command to associate a text description with a neighbor. Use the no form of the command to remove the description. Use this command to enter address family configuration mode to configure a routing session using standard IP Version 4 address prefixes. Use the no form of this command to remove the IPv4 address family configuration from the running configuration. Use this command to apply a route map to incoming or outgoing routes. Use the no form of the command to remove the route map. Use this command to set the minimum interval between each transmission of Border Gateway Protocol (BGP) routing updates. Use the no form of the command to return to the default configuration. Use this command to disable a neighbor or peer group. Use the no form of this command to reenable a neighbor or peer group. Configuration Examples The following example shows you how to enter address family configuration mode for the IP Version 4 address family: dgs-6600:2>enable dgs-6600:15#configure terminal dgs-6600:15(config)#router bgp 65100 dgs-6600:15(config-router)#address-family ipv4 dgs-6600:15(config-router-af)# Creating BGP Aggregate Entries Use the aggregate-address command to configure BGP aggregate entries. Aggregates are used to minimize the size of routing tables. Aggregation combines the characteristics of several different routes and advertises a single route. The aggregate-address command creates an aggregate entry in the BGP routing table if any more-specific BGP routes are available in the specified range. Using the summary-only parameter advertises the prefix only, suppressing the more-specific routes to all neighbors. DGS-6600 Configuration Guide 297

BGP Configuration commands

Available Customizing Options for BGP Peers
Configuration Examples
The following example shows you how to enter address family configuration mode for the IP Version 4 address
family:
Creating BGP Aggregate Entries
Use the
aggregate-address
command to configure BGP aggregate entries.
Aggregates are used to minimize the size of routing tables. Aggregation combines the
characteristics of several different routes and advertises a single route. The aggregate-address
command creates an aggregate entry in the BGP routing table if any more-specific BGP routes are
available in the specified range. Using the
summary-only
parameter advertises the prefix only,
suppressing the more-specific routes to all neighbors.
Command
Explanation
no bgp default ipv4-unicast
the bgp default command enables the IP version 4
(IPv4) unicast address family for all neighbors.
This affects the BGP global configuration. The no
form of the command to disable this function.
neighbor
{IP-ADDRESS | PEER-GROUP-NAME}
remote-as
AS-NUMBER
Use this command to add an entry to the Border
Gateway Protocol (BGP) neighbor table. Use the
no form of this command to remove an entry from
the table.
neighbor {
IP-ADDRESS
|
PEER-GROUP-NAME
}
description
TEXT
Use this command to associate a text description
with a neighbor. Use the no form of the command
to remove the description.
address-family ipv4 [unicast]
Use this command to enter address family
configuration mode to configure a routing session
using standard IP Version 4 address prefixes. Use
the no form of this command to remove the IPv4
address family configuration from the running
configuration.
neighbor {
IP-ADDRESS |
PEER-GROUP-NAME
}
route-map
MAP-NAME
{in|out}
Use this command to apply a route map to
incoming or outgoing routes. Use the no form of
the command to remove the route map.
neighbor {
IP-ADDRESS
|
PEER-GROUP-NAME
}
advertisement-interval
SECONDS
Use this command to set the minimum interval
between each transmission of Border Gateway
Protocol (BGP) routing updates. Use the no form
of the command to return to the default
configuration.
neighbor {
IP-ADDRESS |
PEER-GROUP-NAME
}
shutdown
Use this command to disable a neighbor or peer
group. Use the no form of this command to re-
enable a neighbor or peer group.
