    DMVPN hub & spoke topology; latest 12.3T IOS releases

    1. test hub powered up
    2. test spoke powered up
    3. IPSEC GRE tunnel establishes
    4. NHRP information exchanged
    5. EIGRP adjacency established
    6. hub powered off
    7. EIGRP adjacancey lost as expected
    8. hub powered back up
    9. EIGRP adjacency is not re-restablish
    10. spoke sends NHRP registration packet at 60 second intervals
    11. hub discards NHRP packet with message
    " %CRYPTO-4-RECVD_PKT_INV_SPI: decaps: rec'd IPSEC packet has invalid
    spi for destaddr=12.0.1.1, prot=50, spi=0xA0B93D34(2696494388),
    srcaddr=14.0.1.1 "

    issuing the command clear cry session or power cycling the spoke
    router,
    allows EIGRP adjacency to be re-established


    a) has anyonne encountered this type of porblem with DMVPN ???
    b) any viable solutions or workaround ???
