Here is the config. How did you understand that is interrupted switched?
interface GigabitEthernet1/0/0
bandwidth 10000000
ip address x.x.x.x.x. no ip redirects
no ip proxy-arp
ip ospf message-digest-key 5 md5 7 xxxxxxxxxxxxxx
no ip mroute-cache
load-interval 30
negotiation auto
no cdp enable
standby 40 ip x.x.x.x
standby 40 priority 120
standby 40 preempt
