I have setup one IPv6 6to4 tunnel between two routers.The tunnel seems to be up and running and I'm able to ping from Router R1 to R2 as well.
However,I would like mirror the WAN port to see the packet structure in wireshark. I don't have a L2/l3 managed switch with me now.How can I mirror the WAN port traffic to one of the port in router itself? say (WAN) FE4 to (LAN)FE0?
