hello,
i´m wondering how the router calculates the transport mtu of a tunnel-interface? what doesi t exactly mean?
Router#show interfaces tunnel 309
Tunnel301 is up, line protocol is up
Hardware is Tunnel
MTU 17867 bytes, BW 100 Kbit/sec, DLY 50000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation TUNNEL, loopback not set
Keepalive not set
Tunnel protocol/transport IPSEC/IP
Tunnel TTL 255
Tunnel transport MTU 1505 bytes
Tunnel transmit bandwidth 8000 (kbps)
Tunnel receive bandwidth 8000 (kbps)
