maximum-prefix
Configures maximum-prefix support in peer-group level templates. This support applies for both IPv4 and IPv6 address families.
Syntax
maximum-prefix 1-4294967295 {1-100 | warning-only}
Parameters
● 1-4294967295 - Maximum number of prefix limit.
● 1-100 - Percentage threshold value at which to generate an warning message. The default value is
75.
● warning-only - Specify warning-only to generate a warning message when limit is exceeded.
Default None.
Command Mode TEMPLATE ADDRESS FAMILY LEVEL
Usage
Information
Configures maximum prefix for a specific template. This configuration is applied to all BGP peers when
inheriting this template.
NOTE: Only the system administer (sysadmin) role is allowed to manage this configuration.
Example
MAA-S4048T-X01-7445(config-router-template)# address-family ipv4 unicast
MAA-S4048T-X01-7445(config-router-bgp-template-af)# maximum-prefix 10 50
warning-only
MAA-S4048T-X01-7445(config-router-template)# address-family ipv6 unicast
MAA-S4048T-X01-7445(config-router-bgp-template-af)# maximum-prefix 20 100

neighbor
Creates a remote IP or unnumbered peer and enters Neighbor Configuration mode.
Syntax
neighbor {ip-address | interface interface-type | unnumbered-auto}
Parameters
● ip-address—Enter the IPv4 or IPv6 address of the neighbor.
● interface interface-type—Enter the interface that connects to an unnumbered neighbor.
● unnumbered-auto—Configure one or more BGP auto unnumbered neighbors.
Default Not configured
Command Mode CONFIG-ROUTER-BGP
Usage
Information
Create a remote peer with the BGP neighbor.
If you configure an unnumbered interface using the interface, or unnumbered-auto options,
ensure that the interface is in Layer 3 mode. Also, enable Router Advertisement globally or on required
interfaces using the ipv6 nd send-ra command. If you do not enable Router Advertisement, the BGP
neighborship does not form. Dell EMC networking recommends configuring the minimum and maximum
advertisement intervals as 3 s and 4 s, respectively.
NOTE: You cannot configure the default VLAN as the connecting interface for an unnumbered
neighbor.
NOTE: To configure these settings for a nondefault VRF instance, you must first enter the ROUTER-
CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name
command.
