5.4.9 Services Using SDP with an LDP IPv6 FEC

The 7705 SAR supports SDPs of type LDP with far-end options using IPv6
addresses. 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 is
not allowed with a BGP or RSVP/MPLS LSP. In addition, the CLI does 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 in 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 that use the LDP control plane (such as T-LDP VPLS and R-VPLS, VLL,
and IES/VPRN spoke interface) have the spoke SDP (PW) signaled with an IPv6
T-LDP session when the far-end option is configured to an IPv6 address. By default,
the spoke SDP for these services binds to an SDP that uses an LDP IPv6 FEC that
matches the prefix of the far end address.
In addition, the IPv6 PW control word is supported with 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.

5.4.10 Mirror Services

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 VC-ID that is configured in the
mirror destination service at the mirror source node. The far-end option is not
supported with an IPv6 address.
