      We had exatly same problem with 12.1.1.11.<br>
      <br>
      We use 12.1.1.11 on SE600 that works only as BGP - no problems at
      all.<br>
      However, on other (listed below) - we had the same f..up as with
      12.1.1.9...<br>
      <br>
      Very, very nasty, no log information, no crash, just randomaticall
      disabled forwarding (even ARP works !)<br>

      I want to warn against SEOS 12.1.1.9...
      <br>
      <br>
      Our config looks more/less like that:
      <br>
      <br>
      - BGP
      <br>
      - IPTV
      <br>
      - BRAS (clips/pppoe)
      <br>
      - other supplementary contexts
      <br>
      <br>
      2x 4x10G (PPA3) cards.
      <br>
      LAGs:
      <br>
      1/2 + 2/2
      <br>
      1/3 + 2/3
      <br>
      1/4 + 2/4
      <br>
      <br>
      ports 1/1 and 2/1 work as single ports (some services do not work
      on LAG)
      <br>
      <br>
      ---------
      <br>
      <br>
      2 times within 48 hours we had a sitiuation, that one of cards
      just stopeed forwarding packages.
      <br>
      No worning, no crash. All BGP sessions remained UP, BFD UP, but
      forwarding didn't work or worked randomatically.
      <br>
      This caused affection of non working BGP routes from other
      routers, so all our autonomous system was OUT for a while.
      <br>
      <br>
      We had to make emergency downgrade to previous release -
      12.1.1.7p1
      <br>
      <br>
      Perhaps in other configurations you should see no problems like
      that, but just to keep you informed - there could be some
      problems.
      <br>
      <br>

      <br>
      Marcin Kuczera
