Modifying The Ecmp Group Threshold; Bgp Multipath Operation With Link Bankwidth - Dell C9000 Series Networking Configuration Manual

Modifying the ECMP Group Threshold

You can customize the threshold percentage for monitoring ECMP group bundles.
To customize the ECMP group bundle threshold and to view the changes, use the following commands.
• Modify the threshold for monitoring ECMP group bundles.
CONFIGURATION mode
link-bundle-distribution trigger-threshold {percent}
The range is from 1 to 90%.
The default is 60%.
• Display details for an ECMP group bundle.
EXEC mode
show link-bundle-distribution ecmp-group ecmp-group-id
The range is from 1 to 64.
Viewing an ECMP Group
NOTE: An ecmp-group index is generated automatically for each unique ecmp-group when you
configure multipath routes to the same network. The system can generate a maximum of 512 unique
ecmp-groups. The ecmp-group indices are generated in even numbers (0, 2, 4, 6... 1022) and are for
information only.
You can configure ecmp-group with id 2 for link bundle monitoring. This ecmp-group is different from
the ecmp-group index 2 that is created by configuring routes and is automatically generated. These two
ecmp-groups are not related in any way.

BGP Multipath Operation with Link
Bankwidth
BGP Link Bandwidth (LB) is a way to tell BGP to load-share in an unequal or weighted fashion.
LB is an optional, non-transitive Extended Community that indicates the cost of the (external) link in bytes per
second. LB is similar to the MED attribute and cannot extend beyond the neighboring AS.
