MTU Considerations" + + Before activating a GRE tunnel and periodically thereafter, the GRE + ingress node MUST verify the tunnel's ability to carry a 1280-octet + IPv6 payload packet from ingress to egress, without fragmenting the + payload. Having executed those procedures, the GRE ingress node MUST + activate or deactivate the tunnel accordingly. + + Implementation details regarding the above-mentioned verification + procedures are beyond the scope of this document. However, a GRE + ingress node can verify tunnel capabilities by sending a 1280-octet + IPv6 packet addressed to itself through the tunnel under test. \ No newline at end of file -- cgit v1.2.3
