Hi Pavlin, others,

At the core of our network we've got a Cisco Catalyst 6513 chassis with dual
supervisor engines which take care of L2, management, etc. One supervisor is
active, while the other waits for a failure. 

Each supervisor engine has it's own router, and to enable automatic failover
for our L3 networks, we've deployed HSRP (Hot Standby Router Protocol),
which also allows us to run both routers in an active-active arrangement,
with automatic failover if a fault occurs.

Cheers,
Hefin
