[j-nsp] Framing Errors

[Gordon Smith]

 Hi Paul,

 First, I'd fix up the MTU on those interfaces.
 If the base mtu is 1500, you won't fit a full frame in a dot1q 
 interface under it.
 To fix it, set the base interface mtu high & specify the mtu you want 
 at the subinterface level. e.g.

 interfaces {
     ge-1/0/0 {
         vlan-tagging;
         mtu 9192;
         unit 507 {
             vlan-id 507;
             family inet {
                 mtu 1500;
                 address x.x.x.x/29;
             }
             family inet6 {
                 address xxxx:xxxx:0:4::2/64;
             }
         }
 }
