ESRP Examples

This section provides examples of ESRP configurations.

Single Domain Using Layer 2 and Layer 3 Redundancy

The example shown in Figure 48
perform Layer 2 switching for ESRP domain esrp1 and VLAN Sales. The edge switches are dual-homed
to the BlackDiamond 10808 switches. The BlackDiamond 10808 switches perform Layer 2 switching
between the edge switches and Layer 3 routing to the outside world. Each edge switch is dual-homed
using active ports to two BlackDiamond 10808 switches. ESRP is enabled on each BlackDiamond 10808
switch for the ESRP domain esrp1 that interconnects to the edge switches. Each BlackDiamond 10808
switch has the VLAN Sales configured using the identical IP address. The BlackDiamond 10808 switches
then connect to the routed enterprise normally, using the desired routing protocol (for example, RIP or
OSPF).
