How to schedule a router configuration

hugh2_nguyen · ‎09-29-2009

Hi,

I'm using 2800's and 3800's routers running OSPFv3 IPv4 address family and I would like to schedule an interface configuration so that it would take effect at a certain hour.

For example, I would like to crank up OSPF cost of interface f0/0 at 2300 hours(11PM) using static cost command:

int f0/0 "ospfv3 instance 64 cost 3000"

And at 0600 hours (6AM), I would like to undo the static ospf cost so that dynamic cost would be set by OSPF protocol:

int f0/0 "no ospfv3 instance 64 cost 3000"

Would you please give some advice on how to schedule the configuration. Thanks.

Hugh

You could use the Embedded Event MAnager for this. An applet like the following would work:

event manager applet ospf-cost-inc

event timer cron cron-entry "0 23 * * *"

action 1.0 cli command "enable"

action 2.0 cli command "config t"

action 3.0 cli command "int fa0/0"

action 4.0 cli command "ospfv3 instance 64 cost 3000"

action 5.0 cli command "end"

event manager applet ospf-cost-dec

event timer cron cron-entry "0 6 * * *"

action 1.0 cli command "enable"

action 2.0 cli command "config t"

action 3.0 cli command "int fa0/0"

action 4.0 cli command "no ospfv3 instance 64 cost 3000"

action 5.0 cli command "end"

Mr. Clarke,

Thanks very much. This should work for my routers.
