maximum-paths (IPv6 Address Family
Configuration)
Use this command to limit the number of ECMP next hops in IPv6 routes
from external peers.
Syntax
maximum-paths number-of-paths
no maximum-paths
• number-of-paths—The maximum number of next hops in a BGP route.
The range is from 1 to 32 unless the platform or SDM template further
restricts the range.
Default Configuration
BGP advertises a single next hop by default.
Command Mode
IPv6 Address Family Configuration
User Guidelines
Paths are considered for ECMP when their attributes are the same (local
preference, AS path, origin, MED, peer type and IGP distance). When BGP
uses multiple paths in an ECMP route, BGP still selects one path as the best
path and advertises only that path to its peers.
The following ranges are supported:
• N40xx—1-4
• N30xx—1-16
• N20xx—1-1
Command History
Introduced in version 6.2.0.1 firmware.
