   o  tunnel encap: This can be an encap representing an IP tunnel or
      MPLS tunnel or others as defined in this document.  An optional
      egress interface can be specified to indicate which interface to
      send the packet out on.  The egress interface is useful when the
      network device contains Ethernet interfaces and one needs to
      perform address resolution for the IP packet.
 
I don¹t think an egress interface should be part of the tunnel encap. The
egress interface and optionally a nbr address should be in a separate chain
member.

NB> Removed.


 

<mpls-header> ::= (<mpls-label-operation> ...)
<mpls-label-operation> ::= (<MPLS_PUSH> <MPLS_LABEL> [<S_BIT>]
                            [<TOS_VALUE>] [<TTL_VALUE>]) |
                            (<MPLS_POP> [<TTL_ACTION>])
 
<mpls-header> is part of <tunnel-encap> - so <MPLS_POP> does not make sense?
 

NB> There was no easy place to put the POP operation. One option would have
been to define <tunnel-decap>.

 

Zzh> I think that option is better.

 

Will add <tunnel-decap>

Thanks
Nitin
