Re: RFC 4591 and RFC 4349: DLCI at egress LCCE

Javi,

Because the "port mode" does not have granularity/visibility into the
DLCI level.

Thanks,

Subject: [L2tpext] RFC 4591 and RFC 4349: DLCI at egress LCCE

+ Frame Relay traffic transported in a "virtual circuit-to-virtual 
circuit" mode by L2TPv3 FRPW: Due to local significance of the DLCI, the

egress LCCE re-writes the DLCI.

     RFC 4591 (L2TPv3 FRPW), clause 5
     The Frame Relay frame is transported in its entirety, including the

DLCI ...  The egress LCCE re-writes the DLCI...

+ Frame Relay traffic transported in a "port" mode by L2TPv3 HDLCoPW 
(RFC 4349): It's not mentioned any DLCI modification at the egress LCCE.

Why is it not necessary here (similarly, DLCI significance is local)?
