Removing the HSRP Hello and Hold Timers
To remove the manual timer settings and return the settings to the default values for HSRP group 3, use the
following command:
no standby 3 timers
Configuring a Clear−Text Password for HSRP Authentication
You can specify a clear−text password for the HSRP authentication string for the interface. All interfaces in
the HSRP group use the same authentication string. The syntax is as follow:
standby <HSRP group> authentication <password>
To set the password book1 for HSRP group 3, use the following command:
standby 3 authentication book1
Configuring Two RSFC Interfaces as One HSRP Group
Now that you have learned the commands, let’s look at an example. This project shows how to configure two
RSFC interfaces as part of HSRP group 200 using all the required and optional commands I’ve discussed.
Notice that on both route processors, the same virtual IP address is used for both groups.
Here is the configuration of the first RSFC for the HSRP standby group 200:
HSN_5KRSFC#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
HSN_5KRSFC(config)#interface vlan200
HSN_5KRSFC(config−if)#standby 200 ip 68.187.1.1
HSN_5KRSFC(config−if)#standby 200 priority 150
HSN_5KRSFC(config−if)#standby 200 preempt
HSN_5KRSFC(config−if)#standby 200 timers 5 15
HSN_5KRSFC(config−if)#standby 200 authentication password
HSN_5KRSFC(config−if)#^Z
HSN_5KRSFC#
The following is the configuration of the second RSFC. The priority setting here is lower than that of the first
RSFC; thus the first RSFC is the active route processor (default gateway), and this RSFC is the standby route
processor for the group:
HSN_KRSFC2#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
HSN_5KRSFC2(config)#interface vlan200
HSN_5KRSFC2(config−if)#standby 200 ip 68.187.1.1
HSN_5KRSFC2(config−if)#standby 200 priority 100
HSN_5KRSFC2(config−if)#standby 200 preempt
HSN_5KRSFC2(config��if)#standby 200 timers 5 15
HSN_5KRSFC2(config−if)#standby 200 authentication password
HSN_5KRSFC2(config−if)#^Z
HSN_5KRSFC#
Here’s what happened:
