Administrator Guide

In the above example configuration, a route-map named route1 is created with a clause to set the specified local preference
value, which is 140.
To view the BGP configuration, use the show config command in CONFIGURATION ROUTER BGP mode. To view a route-
map configuration, use the show route-map command in EXEC Privilege mode.
Configuring the local System or a Different System to be the Next Hop for
BGP-Learned Routes
You can configure the local router or a different router as the next hop for BGP-learned routes.
To change how the NEXT_HOP attribute is used, enter the first command. To view the BGP configuration, use the show
config command in CONFIGURATION ROUTER BGP mode or the show running-config bgp command in EXEC
Privilege mode.
You can also use route maps to change this and other BGP attributes. For example, you can include the second command in a
route map to specify the next hop address.
● Disable next hop processing and configure the router (route reflector) as the next hop for a BGP neighbor.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | ipv6-address | peer-group-name} next-hop-self [all]
If you do not use the all keyword, the next hop of only eBGP-learned routes is updated by the route reflector. If you use
the all keyword, the next hop of both eBGP- and iBGP-learned routes are updated by the route reflector.
● Sets the next hop address.
CONFIG-ROUTE-MAP mode
set next-hop ip-address
If the set next-hop command is applied on the out-bound interface using a route map, it takes precedence over the
neighbor next-hop-self command.
Changing the WEIGHT Attribute
To change how the WEIGHT attribute is used, enter the first command. You can also use route maps to change this and other
BGP attributes. For example, you can include the second command in a route map to specify the next hop address.
● Assign a weight to the neighbor connection.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | ipv6-address | peer-group-name} weight weight
weight: the range is from 0 to 65535. The default is 0.
● 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 configuration override the weight
assigned using the neighbor weight command.
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 configuration example, the weight attribute for routes received from the neighbor 10.10.10.1 is set to 150.
To view BGP configuration, use the show config command in CONFIGURATION ROUTER BGP mode or the show
running-config bgp command in EXEC Privilege mode.
