Configuring MPLS LDP IS-IS Synchronization

This task explains how to enable Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP)
IS-IS synchronization. MPLS LDP synchronization can be enabled for an address family under interface
configuration mode. Only IPv4 unicast address family is supported. This task is optional.
SUMMARY STEPS
1. configure
2. router isis instance-id
3. interface type interface-path-id
4. address-family ipv4 unicast
5. mpls ldp sync [ level { 1 | 2 }]
6. commit
Purpose
(Optional) Configures the maximum number of parallel paths
allowed in a routing table.
(Optional) Defines the administrative distance assigned to routes
discovered by the IS-IS protocol.
(Optional) Configures an IS-IS instance with an attached bit in the
Level 1 LSP.

Configuring MPLS LDP IS-IS Synchronization
• This example specifies an IPv6 prefix, and the command
must be in the form documented in RFC 2373 in which the
address is specified in hexadecimal using 16-bit values
between colons.
• Note that IPv6 prefixes must be configured only in the IPv6
router address family configuration submode, and IPv4
prefixes in the IPv4 router address family configuration
submode.
• A different administrative distance may be applied for IPv4
and IPv6.
