interchassis redundancy with SSO do not work

bastien.migette · ‎10-13-2009

Hi, I'm trying to configure high available VPN, for studying purpose.

Here the topology I use:

All the routers can ping each other.

I set this configuration on IAR1 and IAR2:

!

redundancy inter-device

scheme standby HSRPSYNC

!

redundancy

!

ipc zone default

association 1

no shutdown

protocol sctp

local-port 5000

local-ip 10.254.3.2

retransmit-timeout 300 10000

path-retransmit 10

assoc-retransmit 10

remote-port 5000

remote-ip 10.254.3.1

!

but nothing happens, even if I set debug ipc all, debug redundancy status and debug redundancy inter-chassis.

doing show ipc status give me 0 RX/Tx for all values

IAR2#sh redundancy inter-device

Redundancy inter-device state: RF_INTERDEV_STATE_PC_NO_HSRP

Scheme: Standby

Groupname: HSRPSYNC Group State: Init

Peer present: RF_INTERDEV_PEER_COMM

Security: Not configured

IAR2#sh standby bri

P indicates configured to preempt.

|

Interface Grp Prio P State Active Standby Virtual IP

Fa0/1 0 100 Active local 10.254.3.1 10.254.3.254

IAR2#

I use IOS 12.4-25b on a 7200 router

Any clues ?

Many thanks

I hope you don't have the exact same config on both, maybe you forgot to change :

local-ip 10.254.3.2

remote-ip 10.254.3.1

to

local-ip 10.254.3.1

remote-ip 10.254.3.2

on the other router ?

Yes, I parsed only one, but I set the correct IP addresses.
