Ok, here's a strawman.  Let's discuss this further on the msdp WG
mailing list.

  Bill

P.S. Are there good MIB-writing tools?  I wrote this by hand with a lot
of cutting and pasting.

- ---
- --- Issues:
- --- .  Are there more global MSDP configuration items?
- --- .  Is there a useful way to manage MSDP with no SA caching?
- ---    Should the msdpPeerTable contain "last SA received from this peer"?
- --- .  should msdpPeerMsgsSent & msdpPeerMsgsReceived be reset when

- --- .  It's not clear if the presnece of both msdpSACacheGroupMaskLen and
- ---    msdpSACacheSourceMaskLen will cause strange walk order.
