Delete the VRRP priority and preemption delay configuration on VLANIF 20 of
CORE1.

As service traffic increases, the link between CORE1 and the egress router
has high bandwidth utilization, whereas the link between CORE2 and the
egress router is idle, wasting resources and lowering reliability. To effectively
use the two links, you can configure load balancing on CORE1 and CORE2
so that CORE1 function as the master in some VLANs while CORE2 function
as the master in the other VLANs. The two links then load balance traffic from
all VLANs, effectively using network resources. Configure CORE1 to still
function as the master in VLAN 10, and change the priority of CORE2 so that
CORE2 functions as the master in VLAN 20.
b. Configure load balancing.
Configure CORE2 as the master in VLAN 20 and set the preemption delay to 20s.
