Cisco Cisco CRS-X Multishelf System Release Notes
Auto-IP
In ring topology, when a device is inserted into the ring, the neighboring node interfaces require manual reconfiguration. The auto-IP
feature addresses the problem of manually reconfiguring nodes during insertion, deletion, and movement of nodes within the ring.
The auto-IP feature automatically provides IP addresses to the nodes inserted into the ring.

MPLS Static
The MPLS Static feature introduces ability to statically allocate MPLS label resources and provision static label switched paths
(LSPs). MPLS static feature allows a user to:
(LSPs). MPLS static feature allows a user to:
• Enable MPLS feature on a interface
• Assign a label to a prefix or a VRF
• Create a MPLS LSP
For information on MPLS Static configuration, refer Implementing MPLS Static module in Cisco IOS XR MPLS Configuration Guide
for the Cisco CRS Router. For information on the commands used for MPLS Static configuration, refer MPLS Static Commands
module in Cisco IOS XR MPLS Command Reference for the Cisco CRS Router.

Carrier-Supporting-Carrier Support for MPLS LDP
The carrier-supporting-carrier (CSC) support for MPLS LDP feature enables MPLS label distribution protocol (LDP) to provide
carrier-supporting-carrier (CSC) support for Layer 3 Virtual Private Networks. To support LDP as label distribution protocol between
PE-CE devices in an MPLS CSC L3VPN, LDP is required to operate in multiple VRF contexts. To support multiple VRFs, the LDP
configuration model is be extended to allow VRF sub-mode and per-VRF configuration.

MPLS TE Extended Admin Groups
The MPLS TE extended admin groups (EAG) configuration assigns EAG/AG name to bit-position and associates affinity-names
with TE links. The configuration extends to assign names, up to 256, to TE links over the selected interface and assigns 32 names
per attribute-set and index.

MPLS TE IPv6 Autoroute
The MPLS TE IPv6 Autoroute feature enables the use of IPv4 MPLS TE tunnels for IPv6 routing. The routing protocol IGP (IS-IS)
considers the IPv4 MPLS TE tunnel for IPv6 routing path calculation only if the tunnel is advertised to carry IPv6 traffic. To advertise
the tunnel, either IPv6 autoroute announce (AA) configuration or IPv6 forwarding adjacency (FA) configuration should be made on
the tunnel. Also, the IPv6 has to be enabled on the tunnel so that the tunnel can handle IPv6 traffic.
