you got to see this guy... http://www.youtube.com/watch?v=9UNDhQOTLiw&feature=relmfu
he's got some great tubes on switching... if you are becoming comfortable with fhrp (first hop redundancy protocols) hsrp, et al, then you're gonna love this guy... remember all of this so called advanced stuff has it's roots in etherchannel and first hop redundancy... it can always be related back with analogies...ccnp switch talks a lot about high availablity, which is marketing idiot-speak for redundancy... it all had to come from somewhere

fhrp...
hsrp (hot standby routing ptotocol) and glbp (gateway load balancing protocol) as well as vrrp (virtual router redundancy protocol) are first hop redundancy protocols... hsrp and glbp are cisco proprietary while vrrp is open standard...
the protocol belongs protecting the gateway from failure... the gateway is the first hop... it is essentially a virtual router (logical) as backup to the physical gateway, the next hop... since it protects the gateway it belongs with the gateway...
this has been my dilemma... in most every document i have looked at the placement of the virtual ip has been on the interface, the hardware, the gateway...
that interface, that gateway, may very well be an svi...
dsw1#sh int vlan 10
Vlan10 is up, line protocol is up
Hardware is EtherSVI, address is 000f.8ffe.0980 (bia 000f.8ffe.0980)
for me, it has been vital to recognize these protocols for what they are... first hop protocols... or as is glaringly stated by glbp; gateway...
sometimes i do get ahead of myself...
