nodes is through a VRF. This non-default VRF is supported only for GMPLS signaling; whereas the MPLS-TE
signaling continues to support only the default VRF.
Configuring GMPLS RSVP VRF Signaling: An example
This example shows how to configure RSVP VRF signaling for GMPLS:
configure
rsvp
signalling out-of-band vrf vrf1
!
Here, vrf1 is the name of the VRF which is used to signal GMPLS-UNI. If this configuration is absent, the
signaling for GMPLS tunnels occurs in the default VRF itself.
Restrictions for GMPLS RSVP VRF Signaling
The support for GMPLS - RSVP VRF Signaling is subjected to these restrictions:
•
RSVP authentication is not supported when signaling in non-default VRF.
•
RSVP graceful restart is not supported for non-default VRF neighbors. This is not supported for
GMPLS-UNI either.
•
The IP addresses used for GMPLS-UNI must not overlap with the IP addresses used in the default VRF.
DWDM Transponder Integration
A GMPLS UNI based solution preserves all the advantages of the integration of the DWDM transponder into
the router blade. These advantages include:
•
improved CAPEX and OPEX models
•
component, space and power savings
•
improved IP availability through pro-active protection.
How to Implement GMPLS UNI
A new submode is introduced under the main TE submode to enable GMPLS UNI and to contain GMPLS
UNI configuration.
To implement GMPLS UNI, follow these procedures:
Configuring TE for GMPLS UNI
TE configuration specific to packet tunnels does not affect GMPLS UNI tunnels.
To implement TE configuration for GMPLS UNI, follow these procedures:
Enabling GMPLS UNI Submode
Perform this task to enable GMPLS UNI configuration submode and to configure GMPLS UNI tunnels.
