Configuring CSM VLANs

This section describes how to create a fault-tolerant HSRP secure-mode configuration. To create a

nonsecure-mode configuration, enter the commands described with these exceptions:

•Assign the same IP address to both the server-side and the client-side VLANs.

•Do not use the alias command to assign a default gateway for the server-side VLAN.

Step 1 Configure VLANs on HSRP FT1 as follows:

ip slb mode csm
ip slb vlan 136 client
ip address 10.6.0.245 255.255.0.0
gateway 10.6.0.1
ip slb vlan 272 server
ip address 10.5.0.2 255.255.0.0
alias 10.5.0.1 255.255.0.0
ip slb vlan 71 ft
ip slb ft group 88 vlan 71
priority 30
preempt
interface Vlan136
ip address 10.6.0.2 255.255.0.0
standby 1 priority 100 preempt
standby 1 ip 10.6.0.1
standby 1 track Fa3/6 10

Step 2 Configure VLANs on HSRP FT2 as follows:

ip slb mode csm
ip slb vlan 136 client
ip address 10.6.0.246 255.255.0.0
gateway 10.6.0.1
ip slb vlan 272 server
ip address 10.5.0.3 255.255.0.0
alias 10.5.0.1 255.255.0.0
ip slb vlan 71 ft
ip slb ft group 88 vlan 71
priority 20
preempt
interface Vlan136
ip address 10.6.0.3 255.255.0.0
standby 1 priority 100 preempt
standby 1 ip 10.6.0.1
standby 1 track Fa3/6 10

Note To allow tracking to work, preempt must be ON.
