Configuring Layer 3 Redundancy with HSRP
Describing Routing Issues
Identifying the Router Redundancy Process
Describing HSRP
An HSRP group consists of the following:
- Active router
- Standby router
- Virtual router
- Other routers
HSRP active and standby routers send hello messages to the multicast address 224.0.0.2 using UDP port 1985.
Identifying HSRP Operations
Describing HSRP States
Describing HSRP Configuration Commands
Optimizing HSRP
Describing HSRP Optimization Options
These options can be configured to optimize HSRP:
- Standby Priority
- Standby Preempt
- Message Timers
- Interface Tracking
interface vlan 10
ip address 10.0.0.2 255.255.255.0
standby 1 ip 10.0.0.1
standby 1 priority 150
standby 1 preempt
standby 1 preempt delay minimum 180
standby 1 track GigabitEthernet 0/1 50
standby 1 timers msec 200 msec 750 |
interface vlan 10
ip address 10.0.0.3 255.255.255.0
standby 1 ip 10.0.0.1
