Chapter 34 Configuring MPLS, MPLS VPN, MPLS OAM, and EoMPLS
Configuring MPLS OAM and IP SLAs MPLS
This is an example of configuring an LSP traceroute:
Switch#
traceroute mpls ipv4 10.131.159.251/32 destination 127.0.0.1 127.0.0.2 1 ttl5
Using LSP Ping for Pseudowire (AToM VCCV)
Entering the ping mpls pseudowire privileged EXEC command invokes the functionality of MPLS
VCCV, which is the ability to inject traffic control into an AToM virtual circuit and have it intercepted
by the remote provider edge router instead of being passed to the attachment circuits for switching. The
command requires you to enter the egress provider edge IP address and a virtual-circuit identifier.
Beginning in privileged EXEC mode, follow these steps to configure LSP ping over pseudowire:

Configure LSP ping over pseudowire. The keywords have these
meanings:
•
ipv4-address—Specify the IPv4 address of the peer.
•
vc-id—Specify virtual-circuit identification number. The range is
from 1 to 4294967295.
•
(Optional) destination start-address [end-address
[increment]]—Enter the destination 127 network address or address
range with increment.
•
(Optional) exp exp-bits—Specify the MPLS experimental-field
value in the MPLS header. The range is from 0 to 7. The default is 0.
•
(Optional) interval ms—Specify the time in milliseconds between
successive MPLS echo requests. The range is from 0 to 3600000;
the default is 0.
•
(Optional) pad pattern—Specify that the pad TLV is used to fill the
datagram so that the MPLS echo request is the specified size.
•
(Optional) repeat count—Specify the number of times to resend the
packet. The range is from 1 to 2147483647. The default is 1. If you
do not enter the repeat keyword, the same packet is sent 5 times.
•
(Optional) reply dscp dscp-value—Specify a specific class of
service (CoS) in an echo reply by providing a differentiated services
code point (DSCP) value.
•
(Optional) reply mode {ipv4 | router-alert}—Specify the reply
mode for the echo request packet. Enter ipv4 to reply with an IPv4
packet (the default) or router-alert to reply with an IPv4 UPD
packet with router alert. Router alert is type 2 AToM VCCV.
•
(Optional) revision—Enter the IEFT MPLS ping draft revision
number as 1, 2, or 3.
•
(Optional) size packet-size—Specify the size of the packet with the
label stack imposed as the number of bytes in each ping. The range
is from 40 to 18024. The default is 100.
•
(Optional) sweep minimum maximum size-increment —Send a
number of packets of different sizes.
