Setup Guide

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 congure the router (route reector) as the next hop for a BGP neighbor.
CONFIG-ROUTER-BGP mode
neighbor {ip-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 reector. If you use the all
keyword, the next hop of both eBGP- and iBGP-learned routes are updated by the route reector.
• 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 rst 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 | 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.
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 system supports one path to a destination. You can enable multipath to allow up to 16 parallel paths to a destination.
NOTE
: Dell Networking recommends not using multipath and add path simultaneously in a route reector.
To allow more than one path, use the following command.
The show ip bgp network command includes multipath information for that network.
• Enable multiple parallel paths.
CONFIG-ROUTER-BGP mode
maximum-paths {ebgp | ibgp} number
Border Gateway Protocol IPv4 (BGPv4)
