Mam taki o to przypadek: |R1|--- |SW1|---|SW2|---|R2|
Siec LAN bardzo prosta, jeden VLAN i wszytko niemal "na default". Pomiedzy R1 a R2 wlaczone jest HSRP w podstawej konfiguracji:
Kod: Zaznacz cały
R1
ip address 10.151.1.2 255.255.0.0
standby 12 ip 10.151.1.1
standby 12 preempt
R2
ip address 10.151.1.3 255.255.0.0
standby 12 ip 10.151.1.1
standby 12 priority 95
Kod: Zaznacz cały
R1
GigabitEthernet0/0 - Group 12
State is Active
11 state changes, last state change 5d19h
Virtual IP address is 10.151.1.1
Active virtual MAC address is 0000.0c07.ac0c
Local virtual MAC address is 0000.0c07.ac0c (v1 default)
Hello time 3 sec, hold time 10 sec
Next hello sent in 1.904 secs
Preemption enabled
Active router is local
Standby router is unknown
Priority 99 (configured 99)
R2
FastEthernet0 - Group 12
State is Standby
53 state changes, last state change 00:45:25
Virtual IP address is 10.151.1.1
Active virtual MAC address is 0000.0c07.ac0c
Local virtual MAC address is 0000.0c07.ac0c (default)
Hello time 3 sec, hold time 10 sec
Next hello sent in 1.412 secs
Preemption enabled
Active router is 10.151.1.2, priority 99 (expires in 8.680 sec)
Standby router is local
- debug standby wyglada w ten sposob ze HSRP hello nie docieraja do R1 od R2. Na R2 widac pakiety in/out, a na R1 tylko out plus dodatkowa linijka czegos co moze byc bledem
