Command History
Usage Guidelines Use the show ip rsvp high-availability database command to display information about the entries in
the read and write databases.
Use the sho
w ip rsvp high-availability database lsp command to display loose hop information. A
loose hop expansion can be performed on a router when the router processes the explicit router object
(ERO) for an incoming path message. After the router removes all local IP addresses from the incoming
ERO, it finds the next hop. If the ERO specifies that the next hop is loose instead of strict, the router
consults the TE topology database and routing to determine the next hop and output interface to forward
the path message. The result of the calculation is a list of hops; that list is placed in the outgoing ERO
and checkpointed with the LSP data as the loose hop information.
Use the sho
w ip rsvp high-availability database lsp-head command on a headend router only. On other
routers, this command gives no information.
