I have two Layer 3 HP procurve switches with spanning tree enabled and with multiple spanning tree instances enabled, the two switches are also with vrrp and provide gateway redundancy which works fine.
I need to connect the two procurve switches to a Cisco layer 3 core switch which links the site to a remote site.
1) What do i have to do to make the hp spanning tree work with the cisco switch spanning tree?
2) Sine all the switches are doing routing and acting also as a router are they also blocking broadcasts ? is so shall i use the ip helper address command if yes why and how?
