Services Using SDP with an LDP IPv6 FEC

The SDP of type LDP with far-end and tunnel-farend options using IPv6 addresses is supported.
Note that the addresses need not be of the same family (IPv6 or IPv4) for the SDP configuration to
be allowed. The user can have an SDP with an IPv4 (or IPv6) control plane for the T-LDP session
and an IPv6 (or IPv4) LDP FEC as the tunnel.
Because IPv6 LSP is only supported with LDP, the use of a far-end IPv6 address will not be
allowed with a BGP or RSVP/MPLS LSP. In addition, the CLI will not allow an SDP with a
combination of an IPv6 LDP LSP and an IPv4 LSP of a different control plane. As a result, the
following commands are blocked within the SDP configuration context when the far-end is an
IPv6 address:
•
•
•
SDP admin groups are not supported with an SDP using an LDP IPv6 FEC, and the attempt to
assign them is blocked in CLI.
Services which use LDP control plane (such as T-LDP VPLS and R-VPLS, VLL, and IES/VPRN
spoke interface) will have the spoke-SDP (PW) signaled with an IPv6 T-LDP session when the
far-end option is configured to an IPv6 address. The spoke-SDP for these services binds by
default to an SDP that uses a LDP IPv6 FEC, which prefix matches the far end address. The
spoke-SDP can use a different LDP IPv6 FEC or a LDP IPv4 FEC as the tunnel by configuring the
tunnel-far-end option. In addition, the IPv6 PW control word is supported with both data plane
packets and VCCV OAM packets. Hash label is also supported with the above services, including
the signaling and negotiation of hash label support using T-LDP (Flow sub-TLV) with the LDP
IPv6 control plane. Finally, network domains are supported in VPLS.

Mirror Services and Lawful Intercept

The user can configure a spoke-SDP bound to an LDP IPv6 LSP to forward mirrored packets from
a mirror source to a remote mirror destination. In the configuration of the mirror destination
service at the destination node, the remote-source command must use a spoke-SDP with a VC-ID
that matches the one that is configured in the mirror destination service at the mirror source node.
The far-end option will not be supported with an IPv6 address.
This also applies to the configuration of the mirror destination for a LI source.

Configuration at mirror source node

Use the following syntax to configure at the mirror source node. Note that:
