IPv6 Traceroute over an MPLS network
6
Syntax: [no] ipv6 icmp mpls-response [use-lsp] [no-label-extension]
The mpls-response parameter enables the ICMPv6 traceroute response in default mode. The
feature is enabled by default and configured to use IP routing to forward ICMP messages.
The use-lsp parameter enables forwarding of ICMPv6 error messages along the LSPs configured for
the MPLS domain. By default, using configured LSPs use is disabled.
The no-label-extension parameter disables the use of label stack information in the ICMPv6 error
messages.
The no option disables the ICMPv6 traceroute response configuration. When the ICMP traceroute
feature is disabled, standard traceroute using IPv6 forwarding is used to trace a traffic path
through an MPLS domain.
NOTE
The ipv6 icmp mpls-response command supports TTL expiry for IPv6 packets only.
The output of the show ipv6 traffic command displays counts for ICMPv6 ttl-exceeded error reply
packets.
