we use various terms defined there like "node", "router", "host"
however, making this reference explicit is probably uncommon in IETF drafts (readers are supposed to know this already) - just wanted to check with the authors.
We are agreeing that we should have glossary entries for "node" "router and "host". And we should probably call it "Terminology" rather than "Glossary" since that's more common in IETF documents.
