we have GRE tunnel between data center and remote site on AT & T link in which IP MTU 1476 is configured in tunnel interface at remote site while and no Ip tcp adjust-mss command. And on data center end tunnel is configured with Ip tcp adjust-mss 1436.
so two question here.
1. does mtu and tcp adjust command required at both side of tunnel ?
2. what is difference between both command ?
thanks for help in advance.
As I said I believe that it is best to have both commands together. But I do not believe that it creates problems to have only one at each end. I view these commands as complementary - they both work to address the same problem in different ways. One at each end is ok. I view both together as even better.
