hi Zalion0 ,
just to add one more thing ,one i check the site to site vpn configuration between the two controllers ,i can see the below :
(WW-CTRLR-BCKUP) #show crypto-local ipsec-map
Crypto Map Template"default-psk-redundant-master-ipsecmap" 9999
IKE Version: 1

however when i try to display the preshared key for that vpn ,i got nothing :
(WW-CTRLR-BCKUP) #show crypto-local isakmp key
ISAKMP Local Pre-Shared keys configured for ANY FQDN
-----------------------------------------------------
Key Representation
--- --------------
ISAKMP Local Pre-Shared keys configured by FQDN

FQDN of the host Key Representation

ISAKMP Local Pre-Shared keys configured by Address

---------------------- ------------------ --- --------------
ISAKMP Global Pre-Shared keys configured by Address

so i really not sure what to do now ,will configuring new preshared key using the localip command will overwrite the prehared key configured between the two controller and solve the connectivity issue ? thank you in advance for your answer
