Check whether the hop-count of most inner message is equal to 0
Extract RFC3315 about relay message and hop-count :
20.1.1. Relaying a Message from a Client
If the relay agent received the message to be relayed from a client,
the relay agent places a global or site-scoped address with a prefix
assigned to the link on which the client should be assigned an
address in the link-address field. This address will be used by the
server to determine the link from which the client should be assigned
an address and other configuration information. The hop-count in the
Relay-forward message is set to 0.
20.3. Construction of Relay-reply Messages
A server uses a Relay-reply message to return a response to a client
if the original message from the client was relayed to the server in
a Relay-forward message or to send a Reconfigure message to a client
if the server does not have an address it can use to send the message
directly to the client.
A response to the client MUST be relayed through the same relay
agents as the original client message. The server causes this to
happen by creating a Relay-reply message that includes a Relay
Message option containing the message for the next relay agent in the
return path to the client. The contained Relay-reply message
contains another Relay Message option to be sent to the next relay
agent, and so on. The server must record the contents of the
peer-address fields in the received message so it can construct the
appropriate Relay-reply message carrying the response from the
server.
For example, if client C sent a message that was relayed by relay
agent A to relay agent B and then to the server, the server would
send the following Relay-Reply message to relay agent B:
msg-type: RELAY-REPLY
hop-count: 1
link-address: 0
peer-address: A
Relay Message option, containing:
msg-type: RELAY-REPLY
hop-count: 0
link-address: address from link to which C is attached
peer-address: C
Relay Message option: <response from server>
