Users 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 congure the router (route reector) 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 reector. If you use the all
keyword, the next hop of both eBGP- and iBGP-learned routes are updated by the route reector.
• 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 conguration, 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 reector.
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)
