Catalyst 3750 static route update delay


When I update or remove a static route on the catalyst 3750, it takes somewhere between 1-10 minutes before the route becomes active on the workstations.

Is there a process that runs every x minutes which updates the table or am I just not seeing it? I would like to get the table updated right away.

running IOS (C3750-IPBASEK9-M), Version 12.2(25)SEB

thanks in advance - have a good weekend..

If you can verify the route is in the 3750s' route table, and the clients are usign the 3750 as the default gateway, then it's worth checking the cleint's route table...

If they're Windows do a

route print

And look for any references to the route (or supernets of the route) you've just added...

Changing the route on the 3750 should not take that long. It is instant on the switch side. Issue the command show ip route and check if the static route is installed in the routing table,

If you want to trigger an the update directly also you can issue the command " clear ip route *" This will flush the table and build it again.

Please rate if I could help,
