[Nfd-dev] Changing the MTU size

[Aboodi Ahed Hussein Ali]

Hi,

I am trying to change the MTU size for the ethernet multicast face (remote=ether://[01:00:5e:00:17:aa]) to 127 but  I am not sure how to do that.

I have tried to change the MTU of the multicast face with the below command, but I got "Error 406 when creating face: Cannot create multicast Ethernet faces"
The command: nfdc face create remote ether://[01:00:5e:00:17:aa] local dev://ens33 mtu 127

I have also tried to change the "MAX_NDN_PACKET_SIZE = 127" in the "~/ndn-cxx/ndn-cxx/encoding/tlv.hpp" but I get a fatal exception, "encodes into 413 octets, exceeding the implementation limit of 127 octets, when I run the "nfd-start".

Could you please advise me on how to change it.

Thank you,
Ahed
