You can also use route maps to change this and other BGP attributes. For example, you can include the
following command in a route map to specify the next hop address:
Change WEIGHT attribute
Use the following command in CONFIGURATION ROUTER BGP mode to change the how the WEIGHT
attribute is used.
Use the
show config command in CONFIGURATION ROUTER BGP mode or the show running-config
bgp
command in EXEC Privilege mode to view BGP configuration.
You can also use route maps to change this and other BGP attributes. For example, you can include the
following command in a route map to specify the next hop address:
Enable 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.
Use the following command in the CONFIGURATION ROUTER BGP mode to allow more than one path.
The
show ip bgp network command includes multipath information for that network.
