# HSRPv2

Typically implemented on Distribution Switches

```
int vlan 100
    standby version 2
  standby 100 ip 10.100.0.254
  standby 100 priority 150
  standby 100 preempt
  ip add 10.100.0.1 255.255.255.0
  ipv6 add fe08::1 link-local
  ipv6 add 2001:db8:acad:100::1/64
  standby 1006 ipv6 autoconfig
  standby 1006 priority 150
  standby 1006 preempt
```

Default prio is 100.

## Fine-Tuning

hello and hold timers

```
standby 100 timers msec 250 msec 750
```

Authentication

```
standby 100 authentication md5 key-string MySecret
```

Tracking

```
track 4 int lo0 line-protocol
int vlan 100
    standby 100 track 4 decrement 60
```

# VRRP

Make sure the Switch Database Manager is set correctly

```
sdm prefer dual-ipv4-and-ipv6 default
```

```
fhrp version vrrp v3
int vlan 100
    vrrp 100 address-family ipv4
    address 10.100.0.254
    priority 150
    exit
  vrrp 1006 address-family ipv6
    address fe80::1 primary
    priority 150
    exit
```

## Fine-Tuning

Tracking

```
track 8 int lo0 line-protocol
int vlan 100
    vrrp 100 address-family ipv4
    track 8 decrement 60
    exit
  vrrp 1006 address-family ipv6
    track 8 decrement 60
    exit
```

# GLBP

```
int vlan 100
    glbp 100 ip 10.100.0.254
  glbp 100 priority 150
  glbp 100 preempt
  glbp 1006 ipv6 fe80::1
  glbp 1006 priority 150
  glbp 1006 preempt
```

## Fine-Tuning

Authentication

```
int vlan 100
    glbp 100 authentication md5 key-string MySecret
```

Tracking

```
track 7 int lo0 line-protocol
int vlan 100
    glbp 100 weighting 110 lower 85 upper 105
  glbp 100 weighting track 7 decrement 30
```
