• Advertises label bindings for FEC 10.2.1.0/24 to the LDP peer with the LSR ID 4.4.4.9.

• Does not advertise label bindings of other segments to any peers.

bfd enable

Description

Use the bfd enable command to enable BFD to check the connectivity of the LSPs of the specified FEC.

Use the undo bfd enable command to disable BFD for the LSPs of the specified FEC.

By default, BFD is not configured for connectivity check of LSPs.

You need to enable LSP verification by using the mpls lspv command before executing the bfd enable

command.

The BFD session parameters are those configured on the loopback interface whose IP address is

configured as the MPLS LSR ID. The BFD packets will use the MPLS LSR ID as the source address.

Therefore, before enabling BFD for an LSP, configure an IP address for the loopback interface and

configure the MPLS LSR ID as the IP address of the loopback interface. You can also configure BFD

session parameters for the loopback interface as needed.

Syntax

bfd enable destination-address mask-length [ nexthop nexthop-address [ discriminator local local-id

remote remote-id ] ]

undo bfd enable destination-address mask-length [ nexthop nexthop-address ]

Default level

2: System level

Parameters

destination-address: Specifies the destination address of the FEC.

mask-length: Specifies the destination address mask of the FEC, ranging from 0 to 32.

nexthop nexthop-address: Specifies the next hop address of the FEC. If you specify the FEC next hop, the

BFD inspects the specified LSP. If you do not specify it, the BFD detects all LSPs for the FEC.

discriminator: Specifies the discriminator values of the BFD session.

local local-id: Specifies the local discriminator value of the BFD session. The value ranges from 1 to 32.

remote remote-id: Specifies the remote discriminator value of the BFD session. The value ranges from 1 to

4,294,967,295.
