What I did
Improve the speed of
show vrf
commandHow I did it
It would get interface information from configDB each time for each vrf in
vrfs
, and if the amount of vrf is large, the command will take much time.Therefore, it will reduce the execution time to let it just get interface information once, and using it with all vrf.
How to verify it
Previous command output (if the output of a command-line utility has changed)
New command output (if the output of a command-line utility has changed)
