# Test MPLS encap/decap and forwarding using INET6 as encapsulated protocol
|
|
# Setup four routers connected like this: R1---R2---R3---R4--
|
|
# Goal is to be able to ping from R1 the outermost interface of R4
|
|
# Disable net.inet[6].ip[6].forwarding, enable net.mpls.forwarding
|
|
# Use IPv6 between R1-R2-R3 and IPv4 between R3-R4
|
|
# As we use IPv4 on last link we should use only expl.null there
|
|
# because implicit null will assume IPv4 (as the next-hop)
|
|
# But we can use impl null on R2-R1 link because stack will correctly
|
|
# guess IPv6 (from next-hop)
|
|
# Add route on R1 in order to encapsulate into MPLS the IP6 packets with
|
|
# destination equal to R4 right hand side interface
|
|
# Add MPLS routes on R2 in order to forward frames belonging to that FEC to R3
|
|
# Add MPLS expl.null route on R3 for that FEC, pointing to R4
|
|
# Do the same for the reverse direction (R4 to R1)
|
|
# ping6 from R1 to R4 right hand side interface
