Hi authors,

 I have some questions about this draft:

1、How to check all the RBs'MC-LAG-GROUP-RBRIDGES tlvs are received by 
remote RBs?

2、If the MC-LAG-GROUP-RBRIDGES tlvs of one member are lost, the remote RB 
how to install the MAC tabel will have issues.

3、Section 5.5, load balance on remote RB, does the fib on the hardware 
only install one entry?Then how to differ the flip-flop if it can be 
randomly selected.

4、As shown in Figure 3.1, RB1/RB2/RB3 learn the MAC of H1-4, if each RB 
in the same MC-LAG has to advertise the MC-LAG-GROUP-MAC tlv, 
   it seems unnecessary and adds the difficulty of RB4's control plane 
processing; alternatively, we could let only one RB advertises the 
MC-LAG-GROUP-MAC tlv, 
   as described in question 2, how to install the MAC table arises. 

Thanks&BR.
