Enabling the IP router alert option
NOTE
The set-router-alert-option command is supported only for NetIron XMR and NetIron MLX devices.
The set-router-alert-option command sets the IP router alert option for MPLS BFD packets sent
from the ingress device to the egress device. Brocade devices support the IP router alert option as
defined in RFC 2113. To enable router alert option, enter the following command under the LSP
BFD configuration.
Brocade(config)# router mpls
Brocade(config-mpls)# lsp blue
Brocade(config-mpls-lsp-blue)# bfd
Brocade(config-mpls-lsp-blue-bfd)#set-router-alert-option
Syntax: [no] set-router-alert-option
By default, the router alert option is disabled.
The router alert option configuration is only displayed when BFD is enabled for LSP. This example
shows the router option enabled for LSP blue.
