IP Unicast Commands
rtlookup
rtlookup [<ip address> | <hostname>]
Description
Performs a look-up in the route table to determine the best route to reach an IP address or host.
Syntax Description
Default
N/A.
Usage Guidelines
The output of the
rtlookup
command has been enhanced to include information about MPLS LSPs
associated with the routes. The flags field displayed by this command has been enhanced to indicate the
presence of MPLS next hops. An uppercase
L
indicates the presence of a direct LSP next hop for the
route. A lowercase
l
indicates the presence of an indirect LSP next hope for the route.
An optional
mpls
keyword has been added to the
rtlookup
command. When the
mpls
keyword is
specified, the information displayed is modified; some of the information normally displayed is
omitted, and the LSP endpoint and outgoing MPLS label are displayed instead. The LSP endpoint is the
IP address/prefix of the FEC associated with the LSP. The LSP endpoint matches the destination for
direct LSPs and is a 32-bit prefix address of a proxy router for indirect LSPs.
Example
The following command performs a look up in the route table to determine the best way to reach the
specified hostname:
rtlookup berkeley.edu
