Cisco CRS Series - Configuring Mldp User Interface (Opaque Types) Using the Routing Policy

mLDP FECs for filtering, create a new RPL policy (specific for mLDP FECs) with the necessary show and
configuration commands.) An mLDP FEC consists of 3 tuples: a tree type, root node address, and the opaque
encoding, which uniquely identifies the mLDP LSP. An opaque encoding has a different TLV encoding
associated with it. For each of the different opaque TLV, a unique RPL policy is to be created since the
information in the mLDP opaque encoding is different.
The implementation of mLDP FEC based RPL filter is done in both RPL and LDP components.
•
mLDP FEC
The mLDP FEC Route Policy Filtering is a combination of a root node and opaque types.
◦
Root Node:
Filtering is allowed only at the root node in combination with opaque types.
◦
Opaque Types:
The following are the opaque types allowed to create the Route Policies.
◦
IPV4 In-band type
◦
IPV6 In-band type
◦
VPNv4 In-band type
◦
VPNv6 In-band type
◦
MDT Rosen model (VPN-ID) type
◦
Global ID type
◦
Static ID type
◦
Recursive FEC type
◦
VPN Recursive FEC type
•
mLDP Label Mapping Filtering:
Label mapping filtering is supported either in inbound or outbound directions, based on the user
preference. All default policies applicable in the neighborhood are supported by Label Mapping Filtering.
•
mLDP Feature Filtering:
The RPL policy allows selective features to be enabled, applies to the following feature configuration
commands:
◦
MoFRR
◦
Make Before Break
◦
Recursive FEC
Configuring mLDP User Interface (Opaque Types) Using the Routing Policy
Perform this task to configure the LDP user interface using the route policy to filter Label Mappings and
selectively apply the configuration features. LDP interface can be configured using the various available
mLDP opaque parameters like the Global ID, IPv4, IPv6, MDT, Recursive, Recursive RD, Static ID, VPNv4,
and VPNv6.
