Reference Guide

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.
Example
OS10(conf-router-bgp-10)# log-neighbor-changes
Supported
Releases
10.3.0E or later
maximum-paths
Configures the maximum number of equal-cost paths for load sharing.
Syntax maximum-paths [ebgp number | ibgp number] maxpaths
Parameters
● ebgp—Enable multipath support for external BGP routes.
● ibgp—Enable multipath support for internal BGP routes.
● number—Enter the number of parallel paths, from 1 to 64.
Default 64 paths
Command Mode ROUTER-BGP
Usage
Information
Dell EMC recommends not using multipath and add path simultaneously in a route reflector. To recompute
the best path, use the clear ip bgp * command. The no version of this command resets the value to
the default
NOTE: To configure these settings for a non default 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.
Example (EBGP)
OS10(conf-router-bgp-2)# maximum-paths ebgp 2 maxpaths
Example (IBGP)
OS10(conf-router-bgp-2)# maximum-paths ibgp 4 maxpaths
Supported
Releases
10.3.0E or later
maximum-prefix
Configures the maximum number of prefixes allowed from a peer.
Syntax
maximum-prefix {number [threshold] [warning]}
Parameters
● number—Enter a maximum prefix number, from 1 to 4294967295.
● threshold—(Optional) Enter a threshold percentage, from 1 to 100
● warning-only — (Optional) Enter to set the router to send a log message (warning) when the
maximum limit is exceeded. If you do not set this parameter, the router stops peering when the
maximum prefixes limit exceeds.
Default 75% threshold
Command Mode ROUTER-BGP-NEIGHBOR-AF
Usage
Information
If you configure this command and the neighbor receives more prefixes than the configuration allows, the
neighbor goes down. To view the prefix information, use the show ip bgp summary command output.
The neighbor remains down until you use the clear ip bgp command for the neighbor or the peer
group to which the neighbor belongs. The no version of this command resets the value to the default.
