N/A

Default

Enabled

Configuration Mode

config

History

3.1.0000

Example

switch (config) # ib sm connect-roots

Related Commands

show ib sm connect-roots

Notes

  • This command is relevant only for ‘updn’ and ‘ftree’ algorithm (refer to ‘ib sm routing-engines’ command)

  • This option enforces routing engines (up/down and fat-tree) to make connectivity between root switches and in this way to be fully IBA complaint. This may violate the “deadlock-free” status of the algorithm. Hence, it is recommended to use the command carefully.
