Sending a peer-down followed by a peer-up seems reasonable to me.
Changing these requires a new OPEN message to neighbors, so everything
is going to bounce anyway.

Yours?

Subject: [GROW] BMP loc-rib Peer-Type behavior

Authors,

In section 4.1, we define a new peer type to cover the loc-rib.  This is
mostly a pointer to section 4.2 of RFC 7854.

My question is with regards to Peer AS and Peer BGP ID:

If either of those fields are altered on the router, what is the expected
behavior in BMP?

I have opinions, but would like to see yours. :-)
