The MPLS WG Archive[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index][Thread Index][Author Index][Subject Index] How Egress ATM-LSR/FR-LSR distinguishes IPv4 and IPv6 packets?
Hello, How Egress ATM-LSR/FR-LSR distinguishes IPv4 and IPv6 packets? In the case of Generic Label, RFC 3032 "MPLS Label Stack Encoding" specifies IPv4 Explicit NULL (0) and IPv6 Explicit NULL (2). RFC3034 (MPLS on FR) and RFC 3035 (MPLS using ATM VC Switching) doesn't talk about the similarly to identify Network Layer. When Egress ATM-LSR receives an MPLS packet, how it can identify the packet is IPv4 packet or IPv6? Could some one point me to the document/rfc where I can find the answer? Excuse me if this is a repeated question. I checked in the archive, couldn't find the answer to the following question. Thanks in Advance Naren --------------------~~~~~----------------------- Narendra Reddy Byrapuram Mail: ByrapuramN@netscout.com
