i need to deploy otv on ASR 1004on IOS XE Release 3S.
the problem is that my WAN interface must run GRE tunnel with MTU 1400.
the application sending 1500 Byte - so, the GRE interface need to fragment the traffic.
i understand that there is otv restriction: OTV sets the Don’t Fragment (DF) bit in the IP header for all OTV control and data packets so that the core cannot fragment these packets.
is that means it will not work ?
is tere another option ?
