-v: Displays detailed response information.
ipv4 dest-addr mask-length: Specifies the LDP Ipv4 destination address and the
mask. The mask-length argument ranges from 0 to 32.
destination-ip-addr-header: Specifies the IP header destination address for the

Description Use the
ping lsp command to check the validity and reachability of an LSP.
Example # Ping a specified address by send five packets.
