The link object has name  /org/openmhealth/<user-id>, and a delegation /ndn/edu/ucla(it is ucla router's routable prefix), and it is signed by a cert /org/openmhealth/KEY/<user-id>/...., which is signed by ndnfit trust anchor, a second trust anchor on the testbed.

as I looked the picture in Haitao's original message, a further and related issue is that we should have one router's name (UCLA CS router) as the *prefix* of another router (e.g. /ndn/edu/ucla/remap) -- this confuses forwarding.
By the same token, if "/ndn/edu/ucla/" is configured as name for "region", then the same name must not be used again to name a router.
