Each row entry represents a session that is protected by a bypass tunnel associated with the RSVP protocol running in a virtual router. Entries in this table cannot be created and deleted via SNMP SET operations. An entry in this table is created by the agent when an RSVP session is associated with a bypass tunnel that can protect it. The entry is destroyed when the association is removed, which happens when either the session itself goes down or the bypass tunnel that is protecting it goes down.
