Switches with redundant Layer3 support

Please review the following configuration we're planning to install and say if it would be Layer3 redundand on level of master switches:

routers [CISCO RTR #1]<--->[CISCO RTR #2]

= routers have uplink internet connectivity + connected to each other and to appropriate master switches

master [3400cl #1]<--->[3400cl #2]

= master switches are connected together via 10GbE

cabinets [2650/2848] ... [2650/2848]

= switches in cabinets connected to both master switch (in other words, having 2 uplinks)

The 3400cl switches will run XRRP to provide redundancy to the servers.

We will run OSPF between the cisco routers and the 3400cl switches, with the cisco routers distributing a default route down to the L3 switches and the switches distributing the attached sub-nets to the cisco routers. Should we be OK with this level of inter-operability?

Re: Switches with redundant Layer3 support

Without knowing any details, it looks good in theory. If not already done, read through the advanced traffic mgt guide section on xrrp before implementing...
