Changing the NEXT_HOP Attribute
You can change how the NEXT_HOP attribute is used.
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 as the next hop for a BGP neighbor.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | peer-group-name} next-hop-self
• Sets the next hop address.
CONFIG-ROUTE-MAP mode
set next-hop ip-address
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.
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.
