>    Proper functioning of [RFC1191] path Maximum Transmission Unit (MTU)
>    discovery requires that IP routers have knowledge of the MTU for each
>    link to which they are connected.  As MPLS progresses, [RFC3988]
>    specifies some extensions to LDP in support of LDP LSP MTU discovery.
>    For the LSP created using Border Gateway Protocol (BGP) [RFC3107], it
>    does not have the ability to signal the path MTU to the ingress Label
>    Switching Router (LSR).  In the absence of this functionality, the
>    MTU for the BGP LSP must be statically configured by network
>    operators or by equivalent off-line mechanisms.
