(Sup #2/MSFC #2). Sup #1 is active and Sup #2 is in standby mode in both switches. High availability
is enabled on the supervisor engines. The supervisor engines automatically perform image and
configuration synchronization; you must manually synchronize the images and configurations on the
MSFCs.

VLAN 21 (odd-numbered VLANs)—Configure MSFC #1 in Switch S2 as the primary HSRP router

(priority 110) and configure MSFC #2 as the standby router (priority 109).
Load sharing is achieved by having the even-numbered VLANs routed by Switch S1 and the
odd-numbered VLANs by Switch S2. In a complete switch failure, the remaining switch would service
both even and odd VLANs.
You can achieve further load sharing by using MSFC #2 in Switch S1 as the primary HSRP router for
VLAN 12 and MSFC #2 as the primary HSRP router in Switch S2 for VLAN 23 (see
