for pppoe, decrease the MTU size, something like 1450

my initial config is mtu 1492 - with the help of this forum
and now
i follow your mtu 1450
and still persist popping up the "Vi2 PPP: Outbound cdp packet dropped, NCP not negotiated"
can you give a range for mtu so i can change it easily wihout doubt..
ofc the range from your expertise and i just follow your range
