R0106-HP MSR Router Series MPLS Command Reference(V7)

MPLS OAM commands
bfd discriminator
Use bfd discriminator to configure local and remote discriminators for the BFD session used to verify PW
connectivity.
Use undo bfd discriminator to restore the default.
Syntax
bfd discriminator local local-id remote remote-id
undo bfd discriminator
Default
No local or remote discriminators are configured for the BFD session used to verify PW connectivity. The
system automatically assigns local and remote discriminators to the BFD session.
Views
Cross-connect PW view, cross-connect backup PW view
Predefined user roles
network-admin
Parameters
local local-id: Specifies the local discriminator value for the BFD session. The following matrix shows the
value ranges for the local-id argument:
Hardware Value ran
g
e
MSR2000 1 to 32
MSR3000 1 to 512
MSR4000 1 to 1024
remote remote-id: Specifies the remote discriminator value for the BFD session, in the range of 1 to
4294967295.
Usage guidelines
A BFD session for PW connectivity verification can be established in one the following modes:
• Static mode—Manually specify the local and remote discriminator values by using the bfd
discriminator command. You must specify the discriminators on both the local and remote PEs.
Make sure the local discriminator and remote discriminator on the local PE are the same as the
remote discriminator and local discriminator on the remote PE. Otherwise, the BFD session cannot
be established for the PW.
• Dynamic mode—If you do not specify local and remote discriminators, the system automatically
runs MPLS ping to negotiate the discriminator values.
