Description

Check the operability of MPLS segment routing label-switched path (LSP) connections added by ospf protocol. Type Ctrl+c to interrupt a ping mpls segment routing ospf command.

Options

algorithm algorithm-id (Optional) Specify the flexible algorithm identifier. The range of values is 0 through 255. The default value is 0 which means no algorithm is configured. The algorithm-id in conjunction with the prefix is used to distinguish labelled SR paths.

count `count`	(Optional) Number of ping requests to send. If `count` is not specified, five ping requests are sent. The range of values is `1` through `1,000,000`. The default value is `5`.
destination `address`	(Optional) Specify an address other than the default (`127.0.0.1/32`) for the ping echo requests. The address can be anything within the `127/8` subnet.
detail	(Optional) Display detailed information about the echo requests sent and received.
exp `forwarding-class`	(Optional) Value of the forwarding class for the MPLS ping packets.
`fec`	Ping an LDP-signaled LSP using the forwarding equivalence class (FEC) prefix and length.
instance `routing-instance-name`	(Optional) Allows you to ping a combination of the routing instance and forwarding equivalence class (FEC) associated with an LSP.
logical-system (all \| `logical-system-name`)	(Optional) Perform this operation on all logical systems or on the specified logical system.
p2mp root-addr `ip-address` lsp-id `identifier`	(Optional) Ping the end points of a point-to-multipoint LSP. Enter the IP address of the point-to-multipoint LSP root and the ID number of the point-to-multipoint LSP.
size `bytes`	(Optional) Size of the LSP ping request packet (`88` through `65468` bytes). Packets are 4-byte aligned. For example, If you enter a size of 89, 90, 91, or 92, the router or switch uses a size value of 92 bytes. If you enter a packet size that is smaller than the minimum size, an error message is displayed reminding you of the 88-byte minimum.
source `source-address`	(Optional) IP address of the outgoing interface. This address is sent in the IP source address field of the ping request. If this option is not specified, the default address is usually the loopback interface (`lo.0`).
stitched-protocol	(Optional) Protocol stitched on intermediate node.
sweep	(Optional) Automatically determine the size of the maximum transmission unit (MTU).

Output Fields

When you enter this command, you are provided feedback on the status of your request. An exclamation point (!) indicates that an echo reply was received. A period (.) indicates that an echo reply was not received within the timeout period. An x indicates that an echo reply was received with an error code. Packets with error codes are not counted in the received packets count. They are accounted for separately.

Sample Output
