Service Manual

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
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 | 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 configuration, 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 16 parallel
paths to a destination.
NOTE
: Dell Networking recommends not using multipath and add path simultaneously in a route
reflector.
To allow more than one path, use the following command.
The show ip bgp network command includes multipath information for that network.
