【多选题】Router R1 and R2 are both configured for HSRP.  Which two statements about the HSRP priorities  of these two routers are true？（）
A.
To assign the HSRP router priority in a standby group， the standby group-number priority  priority-value global configuration command must be used.
B.
The default priority of a router is zero （0）.
C.
The no standby priority command assigns a priority of 100 to the router.
D.
Assuming that preempting has also been configured， the router with the lowest priority in an  HSRP group would become the active router.
E.
When two routers in an HSRP standby group are configured with identical priorities， the router  with the highest configured IP address will become the active router.
