Hi,
Please forgive my insufficient knowledge about MVPN,
but I need some advice to answer the MIB doctor's
questions (attached in the end of this mail)
on L2L3-VPN-MCAST-{TC-MIB, MIB}.
a) Format and examples of Tunnel Identifier in PMSI Tunnel Attribute
L2L3-VPN-MCAST-TC-MIB provides a textual convention
(L2L3VpnMcastProviderTunnelId) representing
the Tunnel Identifier of a P-tunnel.
a-1) I would like to know if there is any preferred format
when a Tunnel Identifier is printed.
a-2) In the case that there is no preferred format,
the MIB doctor request us to show some actual
examples of the Tunnel Identifier.
Is there any good reference to see the actual examples?
b) Required information to identify a particular P-tunnel
l2L3VpnMcastPmsiTunnelAttributeTable defined in L2L3-VPN-MCAST-MIB
is a table to provide P-tunnel information.
Currently the index of this table is composed of
information objects representing Flags, Tunnel Type,
MPLS Label, and Tunnel Indentifier in
delivered in PMSI Tunnel Attribute.
I think the index must be composed only of minimal
objects to identify a particular P-tunnel.
Thus, Tunnel Type and Tunnel Indentifier are required
for the index as described in Sec. 7.4.1.1 of RFC6513,
but Flags is not required.
b-1) How about MPLS Label? Is it required to be included in the index?
I hope that someone could give me some help.
Thanks in advance,
