Configuration Procedure

ONFIGURATION
Establish the path by using the signaling protocol RSVP-TE or CR-LDP.
■
To form a TEDB, you must configure the IGP TE extension for the nodes on the
network to send TE LSAs. If the IGP TE extension is not configured, the CR-LSP is
created based on IGP routing rather than computed by CSPF.
Before making the configuration, do the following:
Configure static routing or an IGP protocol to make sure that all LSRs are
■
reachable.
Configure MPLS basic capabilities.
■
Configure MPLS TE basic capabilities.
■
Configuring an MPLS TE tunnel using a dynamic signaling protocol involves these
tasks:

Configuring MPLS TE properties for a link
Follow these steps to configure MPLS TE properties for a link:
To do...
Enter system view
Enter interface view of
MPLS TE link
Configure maximum link
bandwidth
Configure maximum
reservable bandwidth of the
MPLS TE link
Configuring OSPF TE
Configure OSPF TE if the routing protocol is OSPF and a dynamic signaling
protocol is used for MPLS TE tunnel setup.
