● mutlipath-relax — Enter to include prefixes received from different AS paths during multipath
calculation.
Default Enabled
Command Mode ROUTER-BGP
Usage
Information
To enable load-balancing across different EBGP peers, configure the mutlipath-relax option. If you
configure both ignore or multipath-relax options simultaneously, a system-generated error
message appears. The no version of this command disables configuration.
NOTE: To configure these settings for a nondefault VRF instance, first enter the ROUTER-CONFIG-
VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter ROUTER BGP VRF mode using the vrf vrf-name
command.
Example
OS10(conf-router-bgp-10)# bestpath as-path multipath-relax
