Configuring RSVP-TE
The configuration example, shown in Figure 5-2, creates primary and secondary LSP
between the node Glasgow and and the node Birmingham. The steps specifically create
an LSP between Glasgow and Birmingham based on an explicitly routed path via
London with bandwidth, and setup and hold priority profile requirements. A secondary
path is also created which, in the event of failure of a link or node on the primary path,
activates the secondary path for the LSP. This path is Glasgow, Birmingham via
Liverpool.
An initial step of adding RSVP-TE to a VLAN must be carried out for all VLANs
over which the user wishes RSVP-TE LSPs to be signaled. This is a one-time
operation.
The following commands add RSVP signaling capabilities to the specified VLANs:
config mpls add vlan gla-lon rsvp-te
config mpls add vlan gla-liv rsvp-te
The following commands create an LSP profile named Glasgow-Birmingham-pro. LSPs
that use the Glasgow-Birmingham-pro profile are signaled with a reserved bandwidth
of 10 Mbps and an LSP setup and hold priority of 5.
config mpls rsvp-te add profile Glasgow-Birmingham-pro bandwidth 10m
setup-priority 5 hold-priority 5
The following commands define the primary and secondary paths between Glasgow
and Birmingham. The paths are defined such that they originate from a loopback VLAN
called loop and terminate at the endpoint 4.0.0.0.
config mpls rsvp-te add path Glasgow-Birmingham-pri-path 4.0.0.0 from loop
config mpls rsvp-te add path Glasgow-Birmingham-sec-path 4.0.0.0 from loop
The following commands loosely pin each path to an LSR, such that each path takes a
different route to the endpoint 4.0.0.0. Path Glasgow-Birmingham-pri-path is routed
through LSR 1.0.0.0 and path Glasgow-Birmingham-sec-path is routed through LSR
5.0.0.0.
config mpls rsvp-te path Glasgow-Birmingham-pri-path add ero ipaddress
1.0.0.0 strict
config mpls rsvp-te path Glasgow-Birmingham-sec-path add ero ipaddress
5.0.0.0 strict
