Hi, Do we allow unidirectional tunnels ?
router A------------------->------------------router B dual stack dual stack A tunnel is configured on A with: IPv4 source @ = Av4 IPv4 destination @ = Bv4 There is not a configured tunnel on B with A as destination. When a packet is received by B from A (IPv6 packet encapsulated in IPv4), do we need to check whether or not a tunnel is configured from B to A (after decapsulation) before forwarding the packet to the IPv6 next hop? Kind regards, Christophe.
