Concept Guide

• Sets weight for the route.
CONFIG-ROUTE-MAP mode
set weight weight
weight: the range is from 0 to 65535.
NOTE: The weight assigned using the set weight command under route map conguration override the weight
assigned using the neighbor weight command.
Example conguration for changing the WEIGHT attribute
DellEMC# configure terminal
DellEMC(conf)# router bgp 400
DellEMC(conf-router_bgp)# neighbor 10.10.10.1 remote-as 500
DellEMC(conf-router_bgp)# neighbor 10.10.10.1 weight 150
DellEMC(conf-router_bgp)# exit
In the above conguration example, the weight attribute for routes received from the neighbor 10.10.10.1 is set to 150.
To view BGP conguration, use the show config command in CONFIGURATION ROUTER BGP mode or the show running-
config bgp command in EXEC Privilege mode.
Enabling Multipath
By default, the software allows one path to a destination. You can enable multipath to allow up to 64 parallel paths to a destination.
You can congure the maximum number of parallel routes (multipath support) to a destination in BGP.
NOTE
: Dell EMC Networking recommends not using multipath and add path simultaneously in a route reector.
To allow more than one path, use the following command.
• Enable multiple parallel paths.
CONFIG-ROUTER-BGP mode
maximum-paths {ebgp | ibgp} number
Congure the following parameters:
– ebgp: Enable multipath support for external BGP routes.
– ibgp: Enable multipath support for internal BGP routes.
– number: Maximum number of parallel paths. The range is from 2 to 64.
Example conguration for enabling multipath
DellEMC# configure terminal
DellEMC(conf)# router bgp 400
DellEMC(conf-router_bgp)# maximum-paths ibgp 5
DellEMC(conf-router_bgp)# exit
In the above example conguration, the maximum number of parallel internal BGP routes is set to 5, so that only 5 routes can be installed in
a routing table.
The show ip bgp network command includes multipath information for that network.
