Hi WG and authors,
I have read this document and have some questions.
In section 2.1 and 2.2, it says “An Anycast SID or BGP PeerSID MUST NOT appear
in segment list preceding a Replication SID.”
I don’t know BGP PeerSID very well, but for anycast SID, I think it may be
useful and suitable to appear in seg list preceding a Replication SID.
Can you please explain the two things and why MUST NOT ?
In Section 2.1, it says below:
There MAY be SIDs after the
Replication SID in the segment list of a packet.
These SIDs are used
to provide additional context for processing a
packet locally at the
node where the Replication SID is the Active
Segment. The processing
of SIDs following the Replication SID MUST NOT
forward the SR-MPLS
packet to another node.
In Section 2.2, it says below:
There MAY be SIDs after the Replication
SID in the SRH of a packet. These SIDs are used
to provide
additional context for processing a packet
locally at the node where
the Replication SID is the Active Segment. The
processing of SIDs
following the Replication SID MUST NOT forward
the SRv6 packet to
some other node. The restrictions described in
this paragraph apply
to both un-compressed and compressed SRv6
encapsulation.
I feel hard to understand how the SIDs after the Replication SID are used. Does
it mean a “VPN SID” or something like that ?
Thanks
Jingrong
