Multi-Protocol Label Switching (MPLS) Label Switched Path (LSP) Ping
and Traceroute mechanisms are commonly used to detect and isolate
data plane failures in all MPLS LSPs including Pseudowire (PW) LSPs.
The PW LSP Ping and Traceroute elements, however, are not specified
for IPv6 address usage.
Specifically, the Pseudowire FEC sub-TLVs for the Target FEC Stack in
the LSP Ping and Traceroute mechanism are implicitly defined only for
IPv4 Provider Edge (PEs) routers, and are not applicable for the case
where PEs use IPv6 addresses. There is, additionally, a degree of
potential ambiguity in the specification of these sub-TLVs since the
address family is not explicitly specified but it is to be inferred
from the sub-TLV length.
This document updates RFC4379 to explicitly constraint these existing
PW FEC sub-TLVs for IPv4 LDP sessions, and extends Pseudowire LSP
Ping to the IPv6 scenario where an IPv6 LDP session is used to signal
the Pseudowire (i.e., where the Sender's and Receiver's IP addresses
are IPv6 addresses.) This is done by defining two new LSP Ping sub-
TLVs for IPv6 Pseudowire FECs.
