Tried to configure IPSec site to site VPN on two catalysts 6506 and no luck. IOS seems to support it but VPN Tunnel will not come up.
Debugging crypto ipsec gives me:
ipsec_input_classify, ret = FIB_FEATURE_NOERROR
crypto_engine_select_crypto_engine: can't handle any more
Sa_req is NULL
Do Catalysts 6500 series support IPSec VPN w/o installing VPNSM or VPN SPA ?
