DESCRIPTION
"This textual convention represents the tunnel identifier
of a P-tunnel.
The size of the identifier depends on the address family
(IPv4 or IPv6) and the value of the corresponding
L2L3VpnMcastProviderTunnelType object.
The corresponding L2L3VpnMcastProviderTunnelType object
represents the type of the tunneling technology used
to establish the P-tunnel.
The size of the identifier for each tunneling technology
is summarized below.

A L2L3VpnMcastProviderTunnelType object of value
noTunnelId(0) indicates that the corresponding
Provider Multicast Service Interface (PMSI) Tunnel
attribute does not have tunnel information.
The value of the corresponding L2L3VpnMcastProviderTunnelId
object will be a string of length zero.
When the L2L3VpnMcastProviderTunnelType object is of value
rsvpP2mp(1), the corresponding Tunnel Identifier is composed of
Extended Tunnel ID (4 octets in IPv4, 16 octets in IPv6),
Reserved (2 octets), Tunnel ID (2 octets), and
P2MP ID (4 octets).
The size of the corresponding L2L3VpnMcastProviderTunnelId
object will be 12 octets in IPv4 and 24 octets in IPv6.
When the L2L3VpnMcastProviderTunnelType object is of value
ldpP2mp(2), the corresponding Tunnel Identifier is P2MP
Forwarding Equivalence Class (FEC) Element [RFC6388].
The size of the corresponding L2L3VpnMcastProviderTunnelId
object will be 17 octets in IPv4 and 29 octets in IPv6
When the L2L3VpnMcastProviderTunnelType object is of value
pimSsm(3), PimAsm(4), or PimBidir(5), the corresponding
Tunnel Identifier is composed of the source IP address
and the group IP address.
The size of the corresponding L2L3VpnMcastProviderTunnelId
object will be 8 octets in IPv4 and 32 octets in IPv6.
When the L2L3VpnMcastProviderTunnelType object is of value
ingressReplication(6), the Tunnel Identifier is
the unicast tunnel endpoint IP address of the local PE.
The size of the corresponding L2L3VpnMcastProviderTunnelId
object is 4 octets in IPv4 and 16 octets in IPv6.
When the L2L3VpnMcastProviderTunnelType object is of value
ldpMp2mp(7), the Tunnel Identifier is MP2MP FEC Element
[RFC6388].
