Chapter 38: Trunk Group/Failover

Redundant connections are often required between Secure Routers and the switches to which they
connect. The following diagram illustrates Ethernet redundancy between a Secure Router 1000 Series
and a Layer 3 switch using failover on the Secure Router and a trunk group configuration on the switch.

Configuration Details

• Secure Router Ethernet 0 and 1 are connected to ports 1 and 2 of a trunk group configured
switch.
• The trunk group is configured with three IP addresses and a single MAC address. One
IP address is utilized for WAN connectivity; the second address provides for
communication between the switch and Secure Router Ethernet 0. For this configuration,
a third IP address is utilized for the failover path.
• The Secure Router 1000 Series is configured for failover on E0. When E0 loses link
conectivity, it will failover to E1 and continue to pass traffic. When E0 recovers, traffic will
be switched back.
• To manage the Secure Router 1000 Series from the switch during normal mode, ping,
telnet, or SNMP to the Ethernet 0 IP address; during failover mode, ping, telnet, or SNMP
to the Ethernet 1 IP address.
