VLAN Features
The Cisco uBR7200 Series support the following VLAN feature:
• HSRP over ISL in Virtual LAN Configurations, page 1-126
HSRP over ISL in Virtual LAN Configurations
Inter-Switch Link protocol (ISL) is a Cisco protocol for interconnecting multiple switches and
maintaining VLAN information as traffic goes between switches. ISL provides VLAN capabilities while
maintaining full wire speed performance on Fast Ethernet links in full- or half-duplex mode. ISL
operates in a point-to-point environment and will support up to 1000 VLANs. You can define virtually
as many logical networks as are necessary for your environment.
For configuration information for Hot Standby Router Protocol (HSRP) over Inter-Switch Link (ISL)
protocol, refer to these documents on Cisco.com:
• “Configuring Routing Between VLANs with Inter-Switch Link Encapsulation” chapter in the Cisco
