Switch Redundancy

Two Stack Configuration — Example
Switch Redundancy
The ISIS | 7500 switch Configuration E file (found in the ISIS software kit), outlines the redundant APN switch
configuration; see
“Configuration E” on page 98. This is a highly recommended and common configuration in an
ISIS environment. In this configuration VRRP, VRRP-E, HSRP or GLBP (depending on the switch vendor and
firmware version) is used between the redundant ISIS VLANs, while a routing protocol like RIP or OSPF is used
on the uplink to the “House” network. For specific configuration examples by protocol see
“Redundant Switch
Configurations” on page 17
