Hi All
I have following setup :
FR------s0/0/0.401 R4 ------- s0/0/1
In the event of failure of link to FR cloud ; i want s0/0/1 on R4 to come up .
I give :
Rack1R4(config-subif)#do sh run int s0/0/0.401
Building configuration...
Current configuration : 222 bytes
!
interface Serial0/0/0.401 point-to-point
backup delay 0 60 <====
backup interface Serial0/0/1 <====
ip address 148.1.0.4 255.255.255.0
no ip split-horizon
snmp trap link-status
frame-relay interface-dlci 401
end
My issue is :
1) To test the backup config ; I gave " no frame-rel dlci " under
s0/0/0.401 . As expected my backup interface came up .
*Jul 25 06:12:36.463: BACKUP(Serial0/0/0.401): event = primary
interface went down
*Jul 25 06:12:36.463: BACKUP(Serial0/0/0.401): changed state to
"waiting to backup"
*Jul 25 06:12:36.467: BACKUP(Serial0/0/0.401): event = timer expired on primary
*Jul 25 06:12:36.467: BACKUP(Serial0/0/0.401): secondary interface
(Serial0/0/1) made active
*Jul 25 06:12:36.467: BACKUP(Serial0/0/0.401): changed state to "backup mode"
2) But If I shutdown the s0/0/0.401 interface ; I expect the backup
interface to come up . But it does not .
Is there something I am missing . I get s0/0/1 to go to "standby /
disabled " state .
Please guide
Thnx
Gaurav Madan.
