ps examine the design in the attachment;sw1 connected to sw2 via stack &sw1 connected to ds1 also sw2 connected to ds2.(ds1-ds2 running hsrp).this a good physical link or what?what is ur suggestion?this will work proprly?
this very basic hsrp config will provide the following:
* provides primary routing for VLAN 15
* provides backup routing for VLAN 10
* provides primary routing for VLAN 10
* provides backup routing for VLAN 15
you should also look into HSRP Tracking to track specific interfaces for up/down so HSRP can adjust accordingly. (document link previously provided)
i also like to set priorities on all hsrp groups above the default 100. (kind of a failsafe incase someone else adds an hsrp config to a specific group without setting a priority; keeps the new hsrp addition from becoming active accidentally)
i also like to keep hsrp priorities 5 points apart. so if you use Tracking (recommended) the hsrp priorities will not become the same as they would if they were 10 points apart. (tracking by default lowers the tracked interface HSRP priority by 10 when tracking discovers a down interface)
any further input from others on hsrp best practices is welcome.
